Industrial Robots: Future of the Automation World

Robots are the trend today and will continue to be so in the future to a very great extent in the automation industry. The ones which are utilized in plants, factories are termed as industrial robots.

An industrial robot is a manipulator which is designed in order to shift materials, parts and tools and even carry out various programmed tasks in the manufacturing as well as production settings.

They’re restructuring the manufacturing industry and very often utilized to execute duties that are dangerous and inappropriate for humans.

Why industrial robots will forever be the future of the automation world?

  1. Enhancement of Work:

The human being is all-time prone to injuries in the plant but this is not the case with industrial robots.  They’re susceptible to injuries and can perform the same work for long period with augmented quality and output.

Therefore, Industrial robots can be applicable for heavy lifting, monotonous work, working in harmful & contaminated environment and work which requires excessive levels of concentration.

Sometimes, humans have to work in environments which give out immense solvents, noise, heat, dust. These can be very much harmful to the health of the being in a long run. Hence, industrial robots will forever be the future of the automation world.

  1. Economical:

Industrial robots will forever be the future of the automation world because of economic reasons as well. As humans, we tend to charge nominal wages when working on our daily routine. But, then again, when it comes to working dangerous situations, we ask greater and expensive amounts.

But, this is not the same case with industrial robots. All one i.e. manufacturer has to do install robots whenever required in a way that they can operate continuously for 24 hours per day and get the best productivity from them.

Yes, 24 hrs. Making humans work continuously for 24hrs is also not possible in the manufacturing sectors. Because of fatigue and many other reasons, human needs breaks as well.

  1. Pliability:

Robots can be more flexible to change and faster as well. The other benefit of using a robot for any kind of application includes the quality of the resultant components has augmented.

Because of the available programmable controls, end-of-arm tooling and machine vision systems, the industrial robots can perform an extensive variety of repeatable tasks without any break and expensive wages.

Some advanced robotics also brings in flexibility and adaptability to unstable customer needs and on rising expectations for developing new products faster.

Hence, industrial robots will forever be the future of the automation world and a knight in shining armor every single time when a human gives up.


Role of Internet of Things in India’s Digital Transformation

The Internet of Things (IoT) is an all-encompassing term for a network backbone that will host billions of devices and sensors that communicate intelligently. The ‘things’ that make up the IoT range from smart phones, RFID chips, sensors built into vehicles, medical devices, buildings (basically anything that needs to be monitored) – all with a unique identity on the network and with the ability to ‘machine talk’.

This ecosystem of interconnected things and the technology that manages them is expected to have a market potential of $15 billion by 2020 in India alone. The IoT is in fact the inflection point that is expected to transform the global economy, and specifically those economies that plan around it. The Indian government believes in the tremendous opportunities that the IoT presents, and is planning a close synergy between the Digital India programme and the IoT, and has already drafted it into policy. The IoT will be part of the broadband highway that will deliver a wide range of e-governance and citizen services to all corners of the country.

Clearly, the IoT will play a major role in the transformation of India into a digital economy – as the catalyst that empowers our citizens by providing them with transparent governance and services (education, health, legal, financial and safety) at their fingertips. At the heart of this transformation will be a re-engineering and digitizing of government processes, using IT and supporting database and cloud infrastructure to simplify, improve and optimize the various government functions.

Digital India projects like Smart Cities are already going forward using the public-private partnership (PPP) model and will showcase IoT-based solutions for almost all aspects of personal and work lives of Indians. For example, smart traffic and parking solutions to address the pressing urban problem of congestion, smart buildings that automatically manage lighting and ambient temperature based on occupancy, and solid waste management using sensor and location intelligence are a few examples of IoT enabled solutions that directly improve the quality of life of citizens.

IoT-based solutions are not just for urban India; they offer rural citizens access to services that were earlier out of reach. On the premise that a well-connected nation is the first step towards a well-served nation, the first objective of the Digital India programme is providing digital infrastructure as a basic utility to all citizens, so educational, health, governance and financial services can be delivered to otherwise underserved areas.

Digital channels provide farmers and artisans the ability to directly reach extensive national and even global markets. A host of ‘localization’ technologies can help different regions communicate so language is not a barrier. Relevant information and updates are now provided in local languages and scripts. Rural India has demonstrated it is hungry for technology, and has rapidly and instinctively adopted it as quickly as it is offered.
Complementing the Digital India programme is the Make in India programme to encourage local and foreign companies to manufacture IoT infrastructure in India, to supply local and global markets. Here again lies the opportunity to engage rural India by setting up units in these areas and training the local population to take on the employment opportunities that come with it. Providing local opportunities helps stem the rural-urban migration that results in pockets of overpopulation and the associated urban problems.

The IoT is a very real network that promises to bring together the vast and varied country that we are, so we can all move forward into a digital world without losing what makes us unique both at the individual and regional levels.


Totally Integrated Automation in the Digital Enterprise

Digitalization is changing our world – and the production methods used by state-of-the-art manufacturing companies to ensure their long-term competitiveness. Customer requests are becoming more and more individualized. To be able to respond appropriately, plant operators have to shorten their time-to-market and become more efficient and flexible, while maintaining or even improving their quality. It’s no longer enough just to optimize the automation processes: digitalization offers real potential throughout the entire value chain.

Totally Integrated Automation (TIA) already offers everything needed to turn the benefits of digitalization into genuine added value. This is where the data is generated from a common base to form the digital twin. Enhanced with new discoveries, the data is fed back again into the automation level to ensure continuous optimization of production – all to ensure your competitive edge.

The Totally Integrated Automation Portal (TIA Portal) can be used to automate engineering tasks. This makes it possible to automatically generate the HMI visualization using SiVArc, and to create standard modules in the TIA Portal that can be re-used to save time. Communication uses the open TIA Portal Openness interface.

Use STEP 7 and TIA Portal to simulate and test the controller functions right at the configuration and engineering stages, with no need for real hardware. This greatly reduces the time and error rate involved in the actual commissioning process.

Data isn’t only generated by individual machines: entire production lines create data, too. With the open interface OPC UA, TIA not only lets machines share this data with each other but also enables it to be used by the enterprise IT systems or via the Cloud. Data analysis then facilitates valuable insights into how your production lines are performing.


The Future of Manufacturing

As manufacturing facilities incorporate greater levels of automation, the demand for new technologies continues to grow. Recent years have seen several trends create a shift in the way the industry operates. With 2017 nearing, it’s time to reflect on the automation trends that will influence and change manufacturing operations in 2017.

Machine Learning: Improving Accuracy at Every Phase

Promising an answer to many modern manufacturing challenges, machine learning is one area of technology that has been subject to rapid development in the last year. Machine learning describes computer science techniques that allow a machine to independently learn a task, rather than being programmed to complete that task. In the era of big data, the greatest advantages of machine learning will come to manufacturers with data-rich production lines. Using the technology, machines can derive patterns and information from existing datasets.

Potential uses include optical part sorting, automated quality control, failure detection and improved productivity and efficiency. Machine learning can improve production capacity by up to 20% and lower material consumption rates by 4%.

Modularization: Fulfilling the Need for Flexibility

Fulfilling customer demand will always be a priority for manufacturers. Changing consumer needs and habits require manufacturers to offer a wider range of products, without reducing product quality and consistency. Considering the competitive nature of today’s industry, the potential to create flexible production lines could not be more valuable. Modularization allows manufacturers to separate, connect or combine different production modules to create customized and varied products in one facility. This change requires the interconnection of industrial machinery and the implementation of intelligent control software.

SCADA: More than Data Acquisition

The integration of predictive analytics in modern SCADA software has made it easy for manufacturers to collect and archive production data and make future predictions based on this intelligence. However, SCADA systems provide much more than an insight into the lifespan of machinery. The integration of cloud computing with SCADA systems has enabled operators to control production from any location, further improving the flexibility of the plant.

As with any cloud migration, there are security concerns. However, as cloud security features become more sophisticated and SCADA providers increasingly adopt a security by design approach to their software, this concern is unlikely to deter manufacturers from embracing – and benefitting from – cloud-based SCADA.


Improving Plant Safety with Industrial Automation

From collaborative robots to machine vision, there is a smart solution to most problems with Industry 4.0. Plant safety is the latest issue which automation is tackling.

Modern components

Traditionally, robots and humans worked separately, with risk of injury reduced only by barriers such as cages and light curtains keeping the partners apart. However, a new generation of collaborative robots specifically designed to work alongside humans is becoming more commonplace in the factory environment.

Collaborative safety solutions such as ABB’s Safe Move allow for humans and robots to work simultaneously on the same task. Through features such as safe position and speed supervision, the flexibility and intuitiveness of humans is combined with the precision, strength and speed of robots. This collaboration increases safety and efficiency during both operations and maintenance.

All-seeing

Machine vision allows automated decision making based on image processing. Primarily used for automated inspections to ensure machinery is optimally running, machine vision can reduce the chance of dangerous events. One example of this is thermal imaging cameras produced by Flir, which allow for an image to be formed from infrared radiation, rather than visual light.

Process control through machine vision uses real time information about a product to improve the manufacturing process, fine tune production and ensure consistent quality control. This happens autonomously, removing the need for humans to work with hot products or in dangerous areas.

Continuous monitoring detects problems before failures occur, preventing stops in production and hazardous situations such as dangerous gases not being burnt off. Specialized technology, like Flir’s thermal cameras, can capture information the naked eye can’t

Smart systems

Machine learning, a type of artificial intelligence (AI), allows computer systems to learn without being explicitly programmed by searching data to find patterns. Any system which uses information to alter the controls of a machine can be subject to machine learning integration. If programmed correctly, machine learning allows the system to not only constantly monitor and adapt to changing conditions, it can also prevent the repetition of previously learnt unsafe scenarios.

Advances in automation technology are aiding in improving both the safety of workers and consumers, by combining the unique problem solving and flexibility of humans with the benefits of robots and automation. This is reminiscent of the collaboration between automotive and technology companies to produce driverless cars, and the resulting inspirational safety record.

 


How the Industrial Internet of Things is Changing the Manufacturing Landscape

In the last few years, manufacturers and industrial organizations around the world are starting to invest in Industrial Internet of Things (IIoT) programs and initiatives to help accelerate the era of IT-optimized smart manufacturing. As IIoT solutions providers better frame, define and create IIoT strategies, many organizations have started to look at what is possible in the age of Industry 4.0 by embracing the Internet of Things and smart manufacturing. In the United States, the number of industrial device-to-device connections is expected to rise to nearly 180 million in 2020 from approximately 50 million in 2014. In China, the rise in machine digitalization is projected to be double that of the U.S. in 2020.

How the Industrial Internet of Things is Changing the Manufacturing Landscape

According to Beth Parkinson, market development director for The Connected Enterprise, Rockwell Automation, there are now four key areas that impact IIoT adoption:

Competition – Economic and political factors are putting more competitive pressure on global companies. Business models – including the people, technology and brand proposition – are under close scrutiny to remain relevant for the long term. As industrial organizations converge their IT and OT systems, and build in more flexibility, they can more easily communicate across their enterprises and respond to market changes.

Workforce – Retirement, economic expansion and technology evolution are overwhelming companies’ ability to staff their operations. Tribal knowledge is leaving with the aging workforce, and incoming talent often lacks the necessary technology skills. Companies that take a multifaceted approach – including more intuitive machine designs, IoT-enabling technologies and advanced training – can better prepare their operations and empower employees through the workforce transformations.

Risks – Smart-manufacturing strategies like remote monitoring and BYOD tactics can create security risks. As a result, companies are starting to implement policies to address these concerns, and help maintain and strengthen system security.

Technology – The ability for an organization to collaborate across departments, including design, operation, maintenance and support is becoming more possible through the IIoT. Companies are able to connect many intelligent devices on one standard network, such as Ethernet, which allows them to capture, move and analyze data across an entire enterprise.

Flexibility – With IIoT and web technology software, the ability for organizations to install, configure and control manufacturing applications from a centralized location is finally a reality. Up until recently, only large industrial organizations could accomplish this. Now, every manufacturer, regardless of size or budget, can embrace digitalization.

Scalability – As scalability has applied to machinery, assembly lines, and conveyance, it now applies to manufacturing software. Software applications can be purchased as manufacturers need them and when production demand requires. Across a broader range of industries different configurations are continuing to expand as manufacturers recognize the value proposition. Strategic IIoT demands that organizations take a fresh look at scalable manufacturing and apply it to equipment that hasn’t traditionally been in the industrial automation mix.


How tomorrow’s plant automation systems will empower users and simplify tasks

Industrial automation systems have helped processing plants increase production value, reduce costs, improve safety, comply with environmental regulations, and more. However, as plants increase in size and complexity, there is the potential for information overload.

New automation systems will enable operators, engineers; maintenance technicians, safety teams, and management to extract context-rich data, helping them gain new levels of operational insight and simplify tasks.

Future-ready teams

Operators are challenged with more instrumentation, more data to be processed, more steps needed to assess and resolve problems, and potentially more human error. New automation systems will bridge the gap between complexity and human capability. Situational libraries based on modeling tools will help reduce response time. Pre-configured templates will improve operator effectiveness, reduce fatigue and errors, and ensure consistency with company procedures. Critical information will be accessible through mobile devices, depending on the process and safety considerations.

Systems engineers need to remedy any production problems quickly. Their environment comprises large numbers of systems, typically from different vendors, each with evolving technologies. With no time to deal with complex flow charts, ladder logic, etc., what’s needed are intuitive, easier-to-use interfaces. One approach is the use of Scientific Apparatus Manufacturer’s Association (SAMA) configuration tools, which present a more accurate representation of the relevant proportional-integral-derivative (PID) blocks and data flows. Users are reporting that SAMA intuitive modeling and dynamism can reduce engineering workloads by as much as 60%.

Project engineers need to stay on top of requirements and costs to be able to deliver upgrades on time. An automation system that decouples the configuration layer from the runtime layers enables portions of a system to be configured and tested in the cloud, speeding project delivery. In addition, cloud-based engineering and project management tools enable real-time, worldwide collaboration.

Maintenance technicians are now dealing with an unprecedented quantity of alarms, and systems from different vendors with multiple communication protocols, toolsets, and manuals. A maintenance response center – akin to an operations alarm management system – will offer dashboards and other information to help technicians determine where to drill down into procedures, as well as help synchronize work with other teams.

Safety team members are responsible for securing the plant from safety breaches and cyber-attacks. To maintain operational integrity, a modern process automation system must integrate safety. This will give the operations team enhanced information regarding where an emergency shutdown is being deployed and the safety protection levels in operation. Dashboards can then provide further context on the company’s risk profile.

Plant executives and managers need a future-ready automation solution that provides an effective perspective across the enterprise, facilitating better and faster business decisions. It should also help integrate execution of plant strategies at every level. For example, a template of the operator situational awareness library would display real-time performance against raw material or energy cost reduction objectives. In this way, new automation systems can help align everyone on the same strategic page, yielding a greater competitive advantage.

A future-proof platform

Many of the applications needed to manage the future have not yet been developed or even imagined. To accommodate them, it’s critical to build on an open, secure system platform. Adherence to common object models will ensure users can more simply incorporate applications built to open computing standards as they become available. These could include:

  • Simulation and modeling – training, online optimization, process control
  • Enterprise manufacturing intelligence – trends in production and operation
  • Corporate energy management – respond to fluctuating energy costs and supply
  • Customized SCADA – e.g. well-field, pipeline, water/wastewater
  • Enterprise asset management – diagnostics, inventory, and predictive maintenance
  • Mobile field apps – procedure guidance and reporting

A future-ready automation system will deliver tremendous competitive and protective benefits. But it will also enlighten plant personnel with the context-rich information they need to improve performance, safety, and gains – for themselves, their employers, and the consumers of their products.


Smart SCADA and Automation System in Power Plants

  1. Introduction :

The goal for any power utility is to maximize their profits and have customer satisfaction. This can be achieved through continuous 24×7 supply of power, cheap, safe and reliable power which should not damage any appliances of the customer .This can be achieved by efficient ,automated power production and distribution and having less power system breakdowns which is achieved by using SCADA systems and automated systems.

An illustration of how a utility can attain maximum profit.-15-4-2017

Fig.1 An illustration of how a utility can attain maximum profit.

  1. SCADA:

SCADA stands for supervisory control and data acquisition is a system operating with coded signals over communication channels so as to provide control of remote equipment. It is an open loop system. The supervisory system may be combined with a data acquisition system by adding the use of coded signals over communication channels to acquire information about the status of the remote equipment for display or for recording functions. SCADA system is used for real time control and monitoring of electrical network from the remote location. The components present in a SCADA system are divided into two units control room and remote station.

  1. Remote Station

Remote Station consists of sensors and actuators that are directly interfaced to the generation plant or equipment’s. The components present in a remote station are:

3.1 Remote Terminal Unit (RTU)

Remote Terminal unit acts as an interface between the field and the SCADA master (D. Bailey et al, 2003; http:// www.ndpl.com/ profile.html; Rajeev Kumar Chandra). It supports control and monitoring of digital and analog data. The RTU panels consist of a power supply card and DO cards, processor, and memory communication card. The RTU panel is powered at 48V.The digital inputs are used to provide the status of switchyard equipment and station auxiliaries. The digital outputs are used for breaker and isolator commands and relay reset commands. There are also junction boxes which are present along with the equipment in order constantly. The general specifications of RTUs are:

  • RTU has two TCP/IP Ethernet ports for communication with Master station(s) using IEC 60870-5-104.
  • Minimum 15 analog values (including 4 energy values) to be considered per energy meter
  • The RTU shall be designed to connect maximum 5 Master stations
  • RTU shall be capable of acquiring analog values through transducers having output as 4-20 mA, 0-10 mA, 0-+10 mA or +/- 5 volts using analog input modules

3.2 Bay Control Unit (BCU)

It is a De-centralized architecture. It is an interface between the field and the SCADA master;it supports the control and monitoring of digital and analog data. BCU has memory unit, DI/DO modules, processor unit, communication unit, power supply unit.

  1. Application of SCADA systems in power plants

4.1 Fault location, Isolation and Service Restoration

This function helps the utility in detecting faults in the the transmission line isolating it from the other grids in order not to affect the flow of power in the neighboring grid. SCADA systems are also responsible to restore the fault area back into service.

4.2 Load Balancing

This function distributes the system total load among the available transformers and the feeders in proportion to their capacities.

Emerging Trends Impacting Industrial Automation Control Market

  • Cloud-based supervisory control and data acquisition (SCADA) systems
  • Increased use of analytics
  • Growing use of programmable automation controllers (PACs)

These are the three biggest trends to influence the industrial automation control market from 2016 to 2020, according to a new report released by international market research company Technavio.

The report predicts these trends will result in an eight percent compound annual growth rate (CAGR) for the Asia-Pacific region, but the trends are likely to be seen globally.

SCADA Systems to See Growth in Adoption

A SCADA system is used for remote monitoring and control of industrial processes such as power generation, fabrication and refining. These systems use coded signals to communicate over channels with remote stations.

Emerging Trends Impacting Industrial Automation Control Market

These systems are predicted to see a growth in adoption due to their scalability, ease of updating and upgrading, as well as general use through the Cloud.

“Generally, SCADA systems are installed to control and monitor sensors and transmitters installed in the facility,” said Bharath Kanniappan, a lead automation analyst at Technavio. “A controller or operator sits inside the facility and controls applications with the help of a human-machine interface. The integration of cloud computing technology with SCADA systems enables operators to control applications via the Internet.”

The chance that hackers could infiltrate cloud-based SCADA systems has raised security concerns. However, this concern is believed to be an unlikely deterrent from adopting the technology, as Cloud security features become more sophisticated.

Analytical Software Will Identify and Reduce Error

Technavio’s report predicts a significant growth in the adoption of data management and analytical software for the purposes of reducing error and assisting with decision making.

The integration of predictive modeling, forecasting, optimization and statistical analysis in software such as SCADA and advanced process control (APC) has made it easier to identify and predict possible errors. In accordance with this prediction, automation vendors have reportedly started to incorporate analytics tools into SCADA and APC.

For example, sophisticated SCADA systems are used in wind and solar-powered energy generation plants.

At times, false alarms in these plants result in shutdowns that reduce efficiency and productivity. Predictive analytics can be used to identify the instance of faulty alarms, thereby raising the efficiency of SCADA systems.

Programmable Automation Controllers to Increase in Use

PAC’s combine the elements of a PC-based controller and programmable logic controllers (PLCs).

Common issues with PLCs are found in the use of ladder logic programming.

This programming language is robust, but time-consuming when compared to the easier-to-program C, C++ and C# languages used in PACs.

Emerging Trends Impacting Industrial Automation Control Market2

Additionally, ladder logic programs are unique between providers, which limits a manufacturer to a single suite of products.

Using C languages with PACs and even some PLCs, a manufacturer can allow logic controllers from different providers to communicate – this flexibility can allow for best-product purchases if one brand doesn’t meet all application requirements.

“PAC uses standard communication protocols that enable it to download and transfer information from various connected systems,” Bharath said. “The technology is more reliable than other control systems such as (DCS), in terms of scalability of production and product flexibility in automotive plants.”


Cloud in Industrial Automation

cloud in automation industryEmbedded devices are becoming increasingly interconnected to enterprises and have become the most least expensive methods to implement. Cloud architecture in automation can be a trend to stay for long, says leading experts.

So what does it mean in the context of industrial automation?

Embedded systems are increasingly being connected to networks in large and mid size enterprises and this is the most cost-effective way of implementing better methods that provide results quickly than usual. In the domain of industrial automation, the usual targets for imbibing cloud computing are manufacturing executing systems (MES) and production planning systems (PPS). There are no requirements for other discrete servers in an industrial set up where there are only few machines or especially manufacturing processes that can be operated much more efficiently when cloud is incorporated in them.

In the field of industrial automation, the incorporation of cloud services has already begun changing the way things work- for instance the architecture of IT structures are being affected as move from a fixed client server architecture  to a more distributed architecture with local as well as global intelligence is constituted.

This is also impacting machine-to-machine (M2M) communication while using embedded cloud. Data and location of intelligence- these paradigms seem to change for the better, as it looks, with the introduction of cloud.

Now, the usual questions that arise are the benefits. Why would manufacturers want to involve cloud based embedded systems in their assemblies and processes?

It is forecasted by experts that the future of cloud networks and embedded systems will be interlinked in the forthcoming days. There will be a marked rise in efficiency, mobility, business productivity and capability because of cloud computing. Costs will be lower and quality standards will be higher because cloud will enable an entire mechanism to perform along its functionalities rather than just being a “box”. The vital transition is expected to be the jump from the isolated embedded world to the new enterprise with the usage of cloud. This will involve better decision-making and also be cost efficient.

 Cloud computing in MES and PPS is already a hard core application in industrial automation. Every machine parameter needs to be properly considered, analyzed post collection. This will help in taking crucial decisions at the blink of an eye.

 How will the entire development process change with the inclusion of cloud computing?

The entire development process remains unchanged but the actual architecture changes. There are however several important points to remember:

  • Data is not local today, in a strict sense. The quality of this specific data will be having its impact on the entire process.
  • The data must be made available beyond static tag mapping.
  • Data security is crucial to keep process disruption away.
  • There needs to be a scale from discrete services to intelligent systems that will allow for the workload consolidation
  • Industrial automation is critical and hence security is the foremost consideration for the smooth running of this entire process.

So what should developers keep in mind while trying to integrate cloud services?

  • Usage of open communication systems and standards
  • Need to eliminate complex architecture
  • Essential to make sure that architecture provides enough separation to scale into cloud

Industrial Robots

Robots are the trend today and will continue to be so in the future to a very great extent in the automation industry. The ones which are utilized in plants, factories are termed as industrial robots.
An industrial robot is a manipulator which is designed in order to shift materials, parts and tools and even carry out various programmed tasks in the manufacturing as well as production settings.
They’re restructuring the manufacturing industry and very often utilized to execute duties that are dangerous and inappropriate for humans. According to a report released by market research company Forrester, by 2021 robots take up 6% of all jobs in the US including customer service representatives and taxi drivers.

1. Enhancement of Work:
The human being is all-time prone to injuries in the plant but this is not the case with industrial robots.  They’re susceptible to injuries and can perform the same work for long period with augmented quality and output.

Therefore, Industrial robots can be applicable for heavy lifting, monotonous work, working in harmful & contaminated environment and work which requires excessive levels of concentration.

Sometimes, humans have to work in environments which give out immense solvents, noise, heat, dust. These can be very much harmful to the health of the being in a long run. Hence, industrial robots will forever be the future of the automation world.

2. Economical:

Industrial robots will forever be the future of the automation world because of economic reasons as well. As humans, we tend to charge nominal wages when working on our daily routine. But, then again, when it comes to working dangerous situations, we ask greater and expensive amounts.

But, this is not the same case with industrial robots. All one i.e. manufacturer has to do install robots whenever required in a way that they can operate continuously for 24 hours per day and get the best productivity from them.

Yes, 24 hrs. Making humans work continuously for 24hrs is also not possible in the manufacturing sectors. Because of fatigue and many other reasons, human needs breaks as well.

3. Pliability:
Robots can be more flexible to change and faster as well. The other benefit of using a robot for any kind of application includes the quality of the resultant components has augmented.

Because of the available programmable controls, end-of-arm tooling and machine vision systems, the industrial robots can perform an extensive variety of repeatable tasks without any break and expensive wages.

Some advanced robotics also brings in flexibility and adaptability to unstable customer needs and on rising expectations for developing new products faster.

Hence, industrial robots will forever be the future of the automation world and a knight in shining armor every single time when a human gives up.

Machine Vision for Factory Automation

Many key tasks in the manufacture of products, including inspection, orientation, identification, and assembly, require the use of visual techniques. Human vision and response, however, can be slow and tend to be error-prone either due to boredom or fatigue. Replacing human inspection with machine vision can go far in automating factory operation, but implementers need to carefully match machine vision options with application requirements.

Nothing fabricated beats human vision for versatility, but other human weaknesses limit their productivity in a manufacturing environment. Boredom, distraction, fatigue, and sometimes even malice can degrade human performance in vision-related factory tasks such as inspection. Factory automation utilizing a machine vision system in such tasks, then, can bring many benefits. Machine vision systems can perform repetitive tasks faster and more accurately, with greater consistency over time than humans. They can reduce lab or costs, increase production yields, and eliminate costly errors associated with incomplete or incorrect assembly. They can help automatically identify and correct manufacturing problems on-line by forming part of the factory control network. The net result is greater productivity and improved customer satisfaction through the consistent delivery of quality products.

 Implementing a cost-effective machine vision system, however, is not a casual task. The selection of components and system programming must accurately reflect the application’s requirements. In addition, selection decisions need to consider more than the initial component costs. Factors such as the time required for system development, installation, and integration with the factory system, the operator training (and retraining) costs, project management, maintenance, and software upgrades and modification, all contribute to the total cost of ownership for the system and should be evaluated before investing in a specific system design

Define the Requirements

 One of the first places to begin in selecting a machine vision system for a factory automation task is to closely define the requirements. There are a number of critical questions to ask up front:

What task does the system need to perform?

Different tasks may require different vision attributes. Inspection requires an ability to examine objects in detail and evaluate the image to make pass/fail decisions. Assembly, on the other hand, requires the ability to scan an image to locate reference marks (called fiducially) and then use those marks to determine placement and orientation of parts. A machine vision system designed for the one task may not be well suited to the other.

Building a Machine Vision

 System while the answers to these operational and functional questions depend on the application, all machine vision systems for factory automation share some fundamental attributes and behaviors. Systems all have a need to image or inspect a scene or object, operating on a continuous basis at the fastest practical speed. Systems all operate by using the following steps:

  • Position the object or camera so that the camera can view the object or scene.
  • Capture an image with a camera.
  • Process the image.
  • Take action

Machine Vision for Factory Automation

Fig. A Machine vision inspection system needs a delivery vehicle as well as a means of taking action when parts fail.

A first step in developing an inspection system, then, is to determine how the parts are to be placed in front of the camera for imaging. In this example, the delivery vehicle is a conveyer belt that carries the objects past the vision system at a constant speed. Other possible delivery vehicles include a part feeder, a robotic arm, or humans placing an object in a station for off-line inspections. Choosing a delivery system can often be the hardest part of a factory automation design because delivery choice will place restrictions on the remaining system choices, including camera, lighting, sensors, and response systems.

 With the delivery system chosen, developers can determine the most appropriate method for triggering the vision system to capture the image, and triggering the response system to take action. In the case of a conveyer belt delivery vehicle, an appropriate sensor might be electronic photo-eyes that produce a signal when the object passes between them. With other delivery vehicles, sensors such as proximity switches or programmable logic controllers (PLCs) could serve. Manual triggering by a human operator is also an option.

 


HMI as the Hub

Not only are HMIs used to display machine and process data, they can also be the data concentrator for all of the plant’s automation systems (figure 1). This is true for PC-based HMIs and for HMIs running on either industry standard or proprietary embedded hardware and software systems.

HMI as the hub

Figure 1. HMIs and networks can provide local and remote connections to a variety of controllers, smart instruments, and other smart devices like motor drives. Data collected using these connections can then be distributed to mobile devices and remote PCs.

In the not too distant past, programmable logic controllers and controllers were connected using discrete I/O, proprietary communication protocols, or maybe even simple ASCII communication. In other cases, a gateway or protocol converter was used. Those days are over for most users, because modern HMIs can act as the hub for tying a variety of controllers and communication protocols together.

HMIs, from lower-cost embedded versions to higher-end PC-based ones, can communicate with many of the leading industrial controllers via dozens or even hundreds of different protocols. With these expanding capabilities, the HMI can connect to most controllers, and Ethernet is becoming the communication standard of choice.

An HMI hub likely uses multiple Ethernet-based protocols simultaneously for communication with several controllers and smart devices. Adding the smarts and programmability of the HMI improves flexibility and functionality, especially when compared to protocol converters or discrete signals.

Particularly with the power of a PC-based HMI, the number of communication ports and configurations that can be deployed is virtually unlimited. New communication paths and networks can be established by just plugging in a new communication card to the PC and activating the appropriate I/O driver in the HMI software.


Distributed Control to Offload PLC

When automation professionals hear the phrase “distributed control system” or its acronym DCS, they usually think about the huge, monolithic and expensive control systems often used in big process plants. Ironically, most distributed control systems in process plants don’t distribute control at all, but instead consolidate it into a few centralized processors.

But, when it comes to machine automation, distributed control means something else entirely. In this case, distributed control means taking a real-time control or data processing task away from the main controller and distributing it to one or more cabinet- or field-mounted controllers. The main reasons for using distributed control are to perform specialized tasks, add redundancy, improve performance and simplify programming.

distributed-control-to-offload-plc

Figure: Machines such as this metal press often require extensive control of hydraulic motion, a task better performed by a distributed controller than by the main PLC (Source: Delta Computer Systems)

Distributed controllers can be used to perform tasks not easily handled by the main controller, particularly if the main controller is a PLC, as opposed to a more powerful PAC. Safety-rated distributed controllers are perhaps the most widespread use of distributed controllers.

Instead of upgrading the main controller to a very expensive safety-rated PLC to handle hundreds of standard and a few safety I/O points, it’s often much more cost-effective to simply add a safety-rated controller to handle the safety I/O. The distributed safety-rated controller can be a simple smart relay if there are just a few points of safety I/O or a small safety-rated PLC to handle more I/O. In either case, savings can be significant as compared to using a safety-rated main controller with its hundreds of I/O points.

Another specialized task often handled by distributed controllers is motion control. Although many PLCs can in theory be programmed to control motion, it’s often more cost-effective to use one or more motion controllers to perform this custom control activity, instead of trying to make the main controller do something a bit outside its main realm of capability.

One of the benefits of using a distributed controller in place of a standard I/O device is that the distributed controller can back up the main controller if it goes down, and take over and safely shut down the process. Another benefit is offloading the main controller from tasks that can consume a significant amount of processing power. And, because control is local, it can often be much faster than with simple remote I/O, which must communicate back and forth with the main controller.

Distributed controllers can be used to enable localized, flexible distributed machine control in applications such as conveying and other material handling systems. Other possible control applications are those in which things have to happen in a certain order such as those utilizing RFID, grippers, die protection, recipes, motor speed, counting, light curtains and other components and functions.


From Process Requirements to Code

Schneider Electric, the global specialist in energy management and automation, announced Prometheus, a configuration tool for defining, programming and documenting all components in an industrial control system, from the Manufacturing Execution System to I/O.

Prometheus introduces an open programming environment that automates complex configuration tasks and enables the configuration of control components, regardless of type or brand.  By removing the burden of updating multiple applications, Prometheus drives greater agility across automation control systems, ensuring plants run the most efficient and up-to-date processes. Prometheus can configure each of these components, beyond the capabilities of existing controllers and SCADA / HMI software – regardless of type or brand, as another industry first.

Code development independent of the target platform, optional functionality and intelligent plug and socket connections deliver agile templates, ensuring the maximum reuse of code. Integrated version management means standards can evolve as requirements change.  A multi user framework provides all engineering disciplines with visibility into the project, ensuring early identification of issues and timely decision-making. Workflows are flexible because each control asset is built as a modular component; work can start at the top with the process definition or at the bottom with the I/O.

Prometheus highlights the incomplete work.  For the operations team, Prometheus delivers total transparency with an online view of executing logic, and total control with simulation to override faults to keep the process running. And with real time process monitoring during change deployment, it is now possible to implement process improvement, and safely deploy to the controller, without disruption. Platform independent and agile code libraries, with intelligent plug and socket assembly, ensure projects are delivered, enabling systems integrators to get on with the job of delivering value to their customers. Reduced dependence on code authors improves resource mobility and customer response. With vendor neutrality, OEMs have access to a broader customer base and embedded control. Prometheus code can even be compiled to GCC for execution on Linux, OS9, OSX or Windows.

Safety PLC’s

      With a growing focus on safety and an increasing number of safety products installed on machinery to protect personnel, end users are finding a greater number of safety relays in their control panels. There is a great desire to reduce panel space and wiring, improve communications and increase the automation of all control systems — including safety. This has piqued the interest in safety programmable logic controllers (PLC’s) in safety-related systems.

     Safety PLC’s provide all of the same functionality of traditional safety relays, but offer space savings and improved communications, while also providing the safety levels needed for the protection of personnel. Used primarily in large systems, safety PLC’s can provide a greater concentration of safety I/O in a smaller footprint than safety relays, saving control panel space and related interwiring. All of the functionality of safety relays, from emergency stops to light curtains to zero speed control, are provided in safety-certified function blocks.

      A variety of communications options are available with safety PLC’s. Some communicate safety-related information via the backplane of the PLC rack and through the cables connecting the various PLC racks, but external communications are typically not safety rated. Others provide safety communications only between the safety PLC processor and remote I/O via a certified safety communications network, and external communications are also non-safety rated. The latter systems can either be used for safety only, non-safety only, or a combination of safety and non-safety-rated communications simultaneously. This allows the user to choose between using one network for both safety and standard control system communications, or separate networks for safety and control running independently from each other – in short, whichever method is the best fit for their application. All safety PLC’s have communications networks available that are not rated for safety but are used for non-safety-rated communications such as diagnostics, allowing them to communicate to other standard PLC’s in the system. This flexibility is important, as many times a user will want to upgrade their safety systems but not disturb the existing control system which is running well. The control system may or may not communicate seamlessly with the safety communications of the safety PLC chosen for the upgrade. They may want to choose a safety PLC that can run an independent safety network amongst all of the safety components and then communicate the data and diagnostics separately to the system to keep the two systems separate. All of these networks can allow improved communications between the safety and control systems, as well as to other supervisory controls. Improved communications along with advanced diagnostics make these safety PLC systems easier to troubleshoot and monitor.

safety-plc

The safety PLC’s software provides users opportunities as well. Some safety PLC’s utilize the same software to program the standard control system as well as the safety-related portions of the control system. Users can appreciate the convenience of being able to program all of the control with the same programming language and software, as there is no new software for technicians to master. The same programming also allows the embedding of safety-related functionality into the rest of the automation and control system. The user does, however, need to make sure the hardware is “non-interfering” and does not have any negative impact on the safety-related components and instructions.

Some safety PLC’s have programming software that operates separately from the rest of the standard control system, and for many users and OEMs, this is the preferred method for the safety system. They want to minimize interactivity between the safety system and the rest of the control system, and also want to make sure that if someone gains access to the standard control system and is able to make changes to it, they will be unable to make any changes to the safety system. Once they have designed the safety system, they feel there should not be any changes made to it, and a separate software system with a different software package helps ensure this.

In short, safety PLC’s can provide many benefits for OEMs and end users, not the least of which is a cost-effective solution to meet application needs. The best rule of thumb for OEMs and end users who have questions about the features and benefits of safety PLC’s is a trusted supplier with experience in integrating them into control systems, which can provide counsel about the most appropriate use in a given application.


Centralized versus Decentralized drive-based

Automation

Unlike controller-based drives that cannot operate without controller direction, a drive-based scheme provides intelligence within the drive itself. Both centralized and decentralized drives with built-in intelligence can run independently with internal controls or via digital controls or other inputs.

A centralized drive-based scheme would be a likely choice for synchronous applications, such as winding, camming, positioning/indexing, and electronic gearing. Drives with enhanced built-in intelligence are capable of making complex calculations and logic-based decisions, as well as communicating from drive-to-drive to perform synchronous functions. In these cases, the physical proximity of the motors to the main control cabinet offers an advantage because all the controls and power distribution are in one central location and can be easily monitored and maintained.

Drive-based control is often preferable to operate larger machinery requiring higher horsepower, such as printing and other converting applications requiring multiple steps. Electronic gearing must occur between printing units, so it is critical that the drives are able to communicate to run at the correct speeds relative to each other.

Synchronous device-based control is a common choice for processing continuous materials, such as paper, film, foil, or textiles. There still may be a PLC communicating basic start-stop and speed control. Intelligence in a drive-based system can even migrate between the drive and a PLC. However, it takes drives with built-in intelligence providing logic and the drive-to-drive communications to run synchronously. In electronic gearing, a master drive conveys its position to all other drives, which follow the master drive’s position.

Camming is an application requiring precise coordination between axes. For a device to cut accurately, the surface material and cutting device must be traveling at exactly the same speed when they contact. Otherwise, some materials will crinkle or tear. Achieving precise coordination between a rotary cutting rod knife and material, for example, both rotating at variable speeds, can be tricky. For example, when the circumference of the knife roll is larger than the cut length, the cutter would generally need to speed up while rotating around and slow down in the cutting zone to match the speed of material while making the cut. The logic and coordination must be constantly occurring between drives in the drive-based or controller-based architecture.

In some cases, machine size may necessitate use of decentralized drive-based control. Long motor cables from a central control cabinet can be eliminated by bringing power to the decentralized drives in a daisy chain, drive-to-drive fashion or by feeding power from a source other than a central control cabinet. Decentralized drive-based inverters can allow for motor-proximity installation. Decentralized inverters can enable even large and complex machines to be more clearly structured, which can be particularly beneficial in applications in the automotive, intralogistics, and other industries.


Advances in Wireless Remote Monitoring

The use of industrial wireless sensor networks has been growing rapidly in the process industries during the past decade. During this time, many stories have been told of successful implementations in process, reliability, and energy industries as well as in health, safety, security, and environmental monitoring applications. Many users across these industries have found that wireless monitoring technologies provide new ways to improve the performance and reliability of their operations.

Measure things that couldn’t be measured before

The cost of wireless sensing networks is significantly less than wired infrastructure due to reduced cost of wiring, cable trays, input/output (I/O) equipment, and associated design, installation, and maintenance labor. This reduced cost makes it possible to implement new applications that previously weren’t financially justified. Wireless level, temperature, and pressure measurements can be installed to monitor the materials improving the capability of operations.

Wireless sensing technologies make it possible to measure processes that could not be measured before. New sensors, combined with analytics software are being applied to applications, such as process emissions, steam trap health, relief valve status, and equipment corrosion monitoring. Previously, these applications required manual inspection using handheld equipment or other manual techniques. With manual inspection, identifying the source of process gases that are being sent to a flare can be very difficult. Now, wireless acoustic monitoring allows companies to identify the source and quantity of material being sent to flares.

wireless-remote-monitoring

Wireless HART networks can enable access to smart field device diagnostics that are stranded by legacy systems. Most legacy control systems don’t have I/O hardware that is capable of HART digital communications with smart field devices. Rich diagnostics and sensor data is trapped in these smart devices with no way for monitoring systems to connect to them. Previously, end users have dealt with this by wiring multiplexers, but this approach is complex and costly to implement. Instead, Wireless HART networks enable access to diagnostic information through the use of wireless transmitters installed on smart devices For example, control valve diagnostic information can be accessed remotely by technicians for online diagnostics and troubleshooting.

Integrate data across information silos

Wireless data shouldn’t stand by itself. Integrating wired and wireless data into analytics and visualization applications increases users’ ability to do more with the data. Wireless data can be integrated into control systems, data historians, and software applications where data from other sources also are available. Before adding wireless measurements, engineers should take inventory of sensor data that is already installed and add new points to complement existing measurements.

When the data is integrated, flexible analytics and visualization platforms enable experts to derive insights and actionable information. Subject matter experts have a more holistic view of data and can make recommendations based on their education and experience. Purpose-built software tools can be used to apply physics principles or empirical models to deepen the level of analysis.

For example, software with first-principle thermodynamic models can be integrated with a data historian to detect equipment performance degradation as an early indication of mechanical problems. An existing heat exchanger might have flow and process temperature measurements that are used by for temperature control, but would require additional temperature and pressure sensors to be installed for performance monitoring. Existing measurements can be combined with new wireless measurements, where mechanical gauges are replaced with wireless transmitters. By expanding the data set to include all of the available measurements, the thermodynamic models can be used by experts to more accurately detect problems and proactively recommend actions to be taken.

Reduce security risks

Stand-alone wireless networks that are used for only measurements, such as acoustics, vibration, and temperature, must be secured for availability, integrity, and confidentiality. However, if these monitoring networks connect to critical control equipment, such as control valves, gas analyzers, or flow meters, the security needs will be much higher. Even in this case, security technologies, such as data diodes can be used to ensure separation of the monitoring network from external threats.

Untethering data

In this time of digital transformation, the companies that use technology in new ways are the ones that gain a competitive advantage. Merely adding measurement points through wireless monitoring won’t reset users’ expectations to achieve new business goals. When users begin strategically using wireless technology to complement their wired infrastructure to address previously unsolvable issues, they can start to advance the performance and reliability of their entire operation.


Wireless Digital Switches and Sensors

Wireless technology has been broadly acknowledged and grasped in the industrial group. New and advancing standards, accessibility of an extensive variety of gadgets, and the demonstrated performance of an expansive installed base each one serve as affirmation to their adequacy.

While there is an extensive choice of gadgets for monitoring, transmitting, receiving and processing consistently variable parameters, (such as flow, temperature, pressure et al), there has been minimal accessible in the method for wireless devices for generating and receiving simple “on-off” signals for machine start/stop control, presence/position sensing, counting, alarm signaling, process control, and other desired digital inputs.

This is currently changing with the improvement and presentation of various powerful, reliable digital contact and non-contact switches, sensors and related accessories.

Accessible and developing control parts include:

  • Mechanical limit switches
  • Contact-type presence sensing switches
  • Non-contact magnetic sensors
  • Non-contact inductive sensors
  • Photo-optical sensors
  • Pull-wire switches
  • Push button switches
  • Momentary and maintained selector switches
  • Key-operated switches
  • Foot switches

BENEFITS:

Lower installation costs– here the elimination of materials (cable, connectors, conduit, cable tray, junction boxes, strain reliefs, et al) and their associated installation labor can result in significant savings.

Reduced maintenance costs – the elimination of cabling also reduces the potential for cable damage and related repair or maintenance costs.

Increased system uptime – as maintenance requirements are reduced, system uptime and productivity can be increased.

APPLICATIONS

  • Valve position monitoring
  • Remote crane control
  • Assembly station inventory management systems
  • Fire vent position monitoring
  • Tank level monitoring
  • Hatch and access port monitoring
  • Hopper flap/diverter monitoring
  • Safety shower/eyewash station alarm monitoring
  • Automatic door control

AUTOMATION IN ROBOTIC INDUSTRY

  • Automation and Robotics :

The usage of automatic equipments in the manufacturing as well as other procedures has been available for decades, ever since the 1950s for the automotive production. Eventually, the technological advancements have allowed increasingly stylish automation with the machines, which can’t do same things repeatedly in the intelligent ways, which has given birth to the perception of robots.

Robotic Automation has seen extremely strong growth in the last decade with manufacturing and industrial sphere. In the year of 2013, as many as 179,000 industrial robots were installed, with a 12% increase against the last year and almost double the numbers of the decade earlier. This strong growth in the robotic automation is expected to be continued in the upcoming years because of improved economic viability and several helpful thematic drivers.

  • Advantages of Industrial Automation in Robotics:

Industrial Automation and Robotics offers complete robotic and automation solutions to a broad range of companies worldwide. With broad experience of this industry, the companies illustrate some advantages of taking on industrial robots for the businesses of all sizes.

Technological advancements have made considerable progress to make production as well as distribution straightforward and well organized. No matter if you are operating a smaller company or bigger business; many solutions of robotic components are available to perform different functions.

Industrial robots may help in:

  • Cost Reduction
  • Quality Improvement
  • Production Increase
  • Improve safety in the workplace

Two important advantages of the industrial robots are their potential to expand and flexibility. Whereas absolute automation solutions might not be suitable for the smaller businesses, the components can be included when required and expanded and customized according to business requirements.

Pneumatics in Everyday Life

Pneumatics is a branch of mechanics that deals with the mechanical properties of gases. It works with the study of pressurized gas that produces mechanical motion, and the application of such gases to produce motion. Systems based on pneumatics are found in factories that deal with compressed air and inert gases. Energy produced by pneumatic systems can be more flexible, less costly, more reliable and less dangerous than some actuators and electric motors.

Though most of us do not realize it, we are surrounded by systems based on pneumatics. Below are some examples.

  • Air brakes on buses and trucks are formally known as compressed air brake systems. These systems use a type of friction brake in which compressed air presses on a piston, and then applies the pressure to the brake pad that stops the vehicle.
  • Exercise machines can be built on pneumatic systems. A pneumatic cylinder creates resistance that can be adjusted with air pressure.
  • Compressed-air engines, also called pneumatic motors, do mechanical work by expanding compressed air. Usually the compressed air is converted to mechanical action by rotary or linear motion.
  • Pressure regulators are valves designed to automatically stop the flow of a liquid or gas when it reaches a certain pressure.
  • Pipe organs produce sound by pushing pressurized air through pipes that are chosen by pressing keys on a keyboard.
  • Cable-jetting is a technique used to put cables into ducts. Compressed air is inserted and flows through the duct and along the cable.
  • Pneumatic mail systems deliver letters through pressurized air tubes. This was invented by a Scottish engineer in the 1800s.
  • Gas compressors are devices that increase the pressure of a gas by reducing its volume.
  • A pneumatic bladder is an inflatable bag technology that can be used to seal drains and ducts to contain chemical gases or spills, to stabilize cargo within a container, or to float an artificial coral reef. They can be used in medical research, and have other applications as well.
  • Pneumatic cylinders use the power of compressed gas to produce a force.
  • A vacuum pump removes gas molecules from a sealed container, leaving behind a partial vacuum. This concept was invented in 1650.
  • Pneumatic air guns use pre-compressed air as an energy source to put a projectile in motion.
  • Barostat systems maintain constant pressure in a closed chamber. They can be used for medical purposes.
  • Gas-operated reloading provides energy to run firearms.
  • Pneumatic tires are created with compressed air to inflate and form the body of a tire on a bike, car, or other vehicle.
  • A handheld jackhammer is a tool that combines a hammer and a chisel, and is usually powered by compressed air.
  • Doors of BRT Buses are operated on pneumatics

As you can see, you will likely encounter some type of pneumatic system on a regular basis in the course of your everyday life.

When to use multi-function safety relays

In applications where single-function relays aren’t capable enough and a safety-rated PLC is overkill, multi-function safety relays can be the best technology choice. Tables provide examples.

Many machines and robots require safety circuits to stop all or part of an operation in the event of an emergency event. Safety circuits are also used to keep all or part of a machine or robot from running while there is human activity in close proximity, for either normal operations or maintenance.

These safety circuits are typically configured using safety relays, or a safety-rated programmable logic controller (PLC) or other safety-rated controller. But in many cases, multi-function safety relays are a better option. A multi-function safety relay is a configurable device with multiple inputs and outputs. It’s more powerful than a single-function safety relay, and less complex and expensive than a safety-rated PLC.

One or more multi-function safety relays can often be used to replace many basic single-function safety relays, simplifying installations and saving money. In other cases, multi-function safety relays can be used instead of a safety-rated PLC, resulting in substantial savings while streamlining implementation and maintenance.

Relays limit options

Machine and robot builder original equipment manufacturers (OEMs), and end users with similar applications often have to monitor and control many input and output (I/O) points that include a relatively small number of I/O points performing safety-related functions.

The most common safety circuit for simple machines and up to three safety inputs (such as an emergency stop [E-stop] and two gate switches) is a basic single-function safety relay that has redundant contacts and is self-monitoring. As a machine or robot’s safety system requires more safety inputs, an option is to keep adding basic single-function safety relays, or to possibly go to a much more expensive safety-rated PLC. Adding basic single-function safety relays to monitor and control the safety I/O often results in overly complex installations involving a relatively large number of relays. If zone control is desired, which requires certain parts of the machine or robot to continue operation for particular types of events, then the number of required safety relays can rapidly multiply, and complexity can grow exponentially.

PLC’s can present problems

For zone control and other complex safety circuits, another solution is to use a safety-rated PLC to control and monitor just the safety I/O, or even all of the I/O, but this can add expensive and unnecessary complexity.

Adding a separate safety-rated PLC in addition to the main controller requires the OEM to purchase, program, and maintain a second programmable system in addition to the main controller. This safety-rated PLC will need its own programming software, with consequent renewal fees. The learning curve for a safety-rated PLC can be steep, and costs are relatively high.


REMOTE MONITORING & ACCESS USING HILSCHER’s ETHERNET TO MPI/DP/PPI CONVERTER FOR SIMATIC S7

When it comes to servicing & maintaining a production system, speed is of primary importance. For this reason, an American manufacturer of equipment for concrete pipe production wanted to add remote maintenance capability to three systems at one of its customer. But in order to be able to monitor the local data stream all the way down to PLC level, a major communications obstacle needed to be removed. Fortunately technologies-Hilscher has a solution that was ready out of the box.

HawkeyePedershaab is world leader in the market of machines for the production of concrete pipes. The company is headquartered in St. Mediapolis, lowa. It was founded in1919 as a production facility for concrete pipes & has developed since into a globally active provider of complete production systems. Presently, there are thousands of production companies in more than 100 countries relying on systems origination from lowa.

WITHOUT HUMAN INTERVATION

“All three systems run with Siemens S7 PLCs & offer practically fully automated operation. Manual intervention is limited to minor aspects, such as changing recipes and updation software”, Hawkeyepedershaab automation engineer Bob Fehr describes the system.

For process automation of its systems, HawkeyePedershaab has. Opted  for the Siemens process control system SIMATIC S7. The communications infrastructure at field level is based upon PROFIBUS DP and the PROFlsafe protocol.

TRANSLATING BETWEEN PROTOCOL

But HawkeyePedershaab wanted to go even one vital step further: “We wanted to take care of errors in the safety networks and be able to configure the system directly from our headquarters in Med, lowa,” Fehr describes the situation. But he also mentions the problem he was confronted with: “The IM151 7F modules do not feature any Ethernet terminals.”

The solution is called netLINK (model NL50-MPI) & was provided by HawkeyePedershaab technology partner Hilscher. The Germany based company is specialized in communications solutions for factory and process automation and operates its own subsidiary in the India.

NetLINK is an intelligent gateway in the form factory of a data bus plug, which can be plugged directly into the S7 PLC. It is based upon the versatile netX chip from Hilscher & is able to read practically any industrial communications protocol and translate it into any other protocol. Power supply is accomplished either directly care of it. In addition, routine management function such as software update or troubleshooting can be accomplished over any distance.


PLC PROGRAMMING LANGUAGES

The International Electrotechnical Commission (IEC) identifies five standard programming languages as the most common for both process and discrete programmable controllers: Ladder Diagram (LD), Function Block Diagram (FBD),

Sequential Function Chart (SFC), Instruction List (IL), and Structured Text (ST)

With the different programming languages available, it’s important to consider a few factors before deciding which to use for your application:

  • Ease of maintenance by the final user: SFC
  • Universal language acceptance: LD
  • Acceptance in Europe: IL or ST
  • PLC speed of execution: IL or ST
  • Applications mainly using digital I/O and basic processing: LD or FBD
  • Ease of changing code: LD
  • Ease of use by newer engineers: ST
  • Ease of implementing complex mathematical operations: ST
  • Applications with repeating processes or processes requiring interlocks and concurrent operations: SFC

Advantages of Using Instruction List (IL):

  • This language consists of many lines of code, with each line representing exactly one operation. Thus, it is very step-by-step in layout and format, which makes the entry of a series of simple mathematical functions easy.
  • In addition, if the programmer uses only the IEC-defined instructions, a program written in this language can be moved easily between hardware platforms.
  • Instruction List language is a low-level language and as such, will execute much faster in the PLC than a graphical language, like Ladder.
  • This language is also much more compact and will consume less space in PLC memory.
  • The simple one line text entry method supported by this language also allows for very fast program entry.

 Advantages of Using STL:

  • STL is a lot more efficient than ladder logic when you need math instructions or other non-Boolean instructions.
  • You can save 50% of memory (and processing time) when you use STL.
  • STL is more efficient due to the fact that STL is the closest language to the machine code, thus less overhead.
  • STL is of course the more difficult language to troubleshoot, but the benefits are fairly clear. STL takes full advantage of how the S7 PLC actually operates for example being able to directly access Address Registers and Accumulators.
  • Some tasks that would take dozens of rungs of ladder can be done in a few lines of nice compact code that is much easier to read and understand.
  • Performing more complex operations like loops and jumps and indirect addressing becomes easier in STL.

IMPACT OF IIOT ON AUTOMATION INDUSTRY

Industrial Internet of Things (IIoT) is creating various new technologies. As a result, automation industry is too fortunate to have a huge range of technologies for problems solving, improving operations and increasing the productivity. The IIoT is the connection of uniquely identifiable electronic devices using Internet, including Internet Protocol (IP), Web services, and cloud computing.

IIOT

The impact of IIoT technology on the automation industry is the use of tablet computers, smart phones, virtualized systems, and cloud storage of historian data.

A good example of a commercial IoT application is the “fitbit” which includes processing, sensors, display, and wireless communications supported by a cloud application. This is essentially a wireless SCADA system. It provides a glimpse into future industrial automation possibilities with end devices such as sensors, actuators, motors, and valves having embedded processing and communications.

The industrial automation industry has always used commercial technologies such as PLCs replacing relays, commercial PCs replacing custom build CRT consoles, Windows operating system replacing proprietary OS, digital control replacing pneumatic/analog electronic, Ethernet replacing proprietary communications, and 802.15.4 wireless sensors.

The conclusion is the application of new technology over the years has reduced the total cost of automation system ownership while increasing the value delivered.


ROLE OF HYDRAULICS IN THE INDUSTRIAL INTERNET OF THINGS

When hearing the terms like industrial internet of things or industry 4.0, the most common technologies stuck to mind are like advanced Ethernet networks, data and cloud computing etc. but the technology like hydraulics never comes to our mind.

The very first point about applicability of hydraulics in the internet of things is its capability for micrometer precision. Electro-hydraulic axis controllers close the control loop decentrally, like electrical servo drives, and harmonize the target or actual position in real time within milliseconds. Operating decentrally suggests that the decentralized intelligence in the electronic control device adjusts the rotational speed of the pump drive on demand. In comparison to common constant drives, this reduces the energy consumption of hydraulic power units by up to 80 percent. Servo-hydraulic axes have an integrated fluid loop and are driven by the same servo drives as the electromechanical versions. Since the axes are encapsulated systems, engineers must only connect power and communication cables for assembly and start-up. Everything else is already stored in the drive software. Modern motion controls for hydraulic drives support all common protocols, such as Sercos, EtherCAT, EtherNet/IP, Profinet RT, Powerlink and Varan.

With these capabilities hydraulic drives are an ideal match for the increasingly integrated and technology-overlapping infrastructure of modern production environments —all the way up to Industry 4.0.

SCADA: Journey of Process Control Centralization from Field to Control Room

Industrial automation is a critical part of industrial enterprises today. Everyday many industries are moving towards centralized plant process monitoring and control through Supervisory Control And Data Acquisition i.e. SCADA Systems. Understanding of process information flow through an automation system monitored and controlled by SCADA is a key skill for every instrumentation and control specialist, no matter whether he is responsible for the design, integration, installation or maintaining such systems.

1. Information Flow:

Figure below shows information flow within SCADA Systems:

The Transducer, sensor or the sensing element, is a basic device that converts physical quantities into an electronically measurable quantity. The Transmitter is an electronic device that converts the transducer output into a “standard electrical signal” measured in Volts or mA, and is capable of transmitting that signal for a relatively long distance. The marshalling provides an easy way to connect, identify and segregate the incoming cables to the control panel, and while the marshalling function has nothing to do with the value of the incoming signal, it provides several benefits such as:

  • Protection for the PLC I/O modules, using fused terminal blocks.
  • Disconnecting individual signals, by means of knife-disconnect terminal blocks.
  • Isolation, by means of interface relays, signal isolators and barriers.

PLCs are handling digital information in bits, bytes (8-bits), words (16-bits) or double words (32-bits). AI module uses 4 words for the four channels (AI0 to AI3), and from each word it uses only 12-bits and the remaining 4-bits are not used.

Scaling is the mathematical operation of converting the RAW analog binary value in an AI register to its corresponding meaningful engineering value, and placing this value in a known memory location “register” in the PLC memory, for further use or manipulation.

2. Network Communication:

For any two devices to exchange data together, four elements must exist:

  • Common Communication Interface
  • Common Language
  • Known Network Addresses
  • Memory Addresses

network communication

The OPC server is a software program that converts the hardware communication protocol used by a PLC into the OPC protocol. The OPC client software is any program that needs to connect to the hardware, such as SCADA. The OPC client uses the OPC server to get data from or send commands to the hardware. Before OPC technology, to connect 3 different SCADA packages to 3 different PLC modules SCADA vendors need to develop 9 different communication drivers. Whereas an OPC vendor need to develop only 3 drivers for 3 PLCs. All SCADA packages will use standard OPC client interface with OPC server.

3. SCADA:

SCADA, it’s where the operator gets to see his process from a top view, give commands, monitor and respond to alarms, generate reports and much more.

SCADA server is software responsible for core SCADA functions, such as data communication with the control hardware (either directly or via OPC server), graphics creation, alarm generation, security, data storage, reports generation … etc.

SCADA client is software responsible for displaying the information gathered (and generated) by the SCADA server, on the graphics screens created also by the SCADA server, relaying operator commands to the SCADA server, trends & reports display … etc

Steps for creating a SCADA program:

  1. Define connections
  2. Define data source
  3. Define tags
  4. Create Graphic displays

 4.Future of SCADA:

From the viewpoint of SCADA frameworks, there are two noteworthy super patterns that will characterize the SCADA arrangement without bounds. They are industrial cyber security and the enterprise ecosystem

Industrial Cyber Security– So as to viably relieve digital assaults, end-clients need to receive a far reaching security system that incorporates basic changes in strategy detailing, foundation of a mechanical digital workforce, multi-level system assurance and expert dynamic risk appraisal.

Enterprise Ecosystem- The calls for top of the line correspondence abilities worked inside the SCADA design, empowering more noteworthy combination with the higher layers of big business programming. This would basically involve a future SCADA framework that crosses the limit of traditional item definition and change into an answer suite that can overcome any issues between the plant floor and business process application. End-clients will discover gigantic advantages in top of the line SCADA frameworks that can incorporate plant floor with big business programming like ERP (undertaking asset arranging), and outline arrangements like PLM (item lifecycle administration). Be that as it may, this outline interest should be a long haul methodology that returns in stages and help computerization sellers manage their administration in an exceedingly aggressive business sector space, in the end.


 Simulation and Modeling Solutions Hugely Benefit Process Industries

Process industries such as power plants, integrated steel plants and refineries are asset and capital intensive. While, it takes typically around 3-4 years to engineer, erect, and commission a process plant involving significant amount of design and engineering efforts, the working life of a well-engineered and operated plant may extend up to30-40 years or even longer

Excellent execution during all the stages required to ensure safe, Profitable, and efficient operation of the plants. Simulation and modelling solutions play performance-Enhancing roles during the entire lifestyle of a process plants.

Simulation involves the generation of artificial history of the systems and observation of the artificial history to draw interference concerning the operational characteristics of the real Systems that is represented.

Simulation is used to describe and analyze the behaviour of systems, ask what-if questions about the real systems, and old in design of real systems. Both existing and conceptual systems can be modelled with simulation.

`Dynamic Simulators are not only useful tools to analyze and troubleshoot abnormal plant behaviours, but also to test new operational and/or control strategies. SCADA systems are also most wildly used Simulation tool used in Industries for operation.


Industrial Automation: Past, Present and Future

industrial automation

PAST

When Manufacturing AUTOMATION was launched in 1986, a quarter century ago, industrial automation was in its heyday. Business was booming and the annual ISA show was a worldwide attraction for the instrumentation, controls and automation industry – with attendance in the tens of thousands. Today, by contrast, industrial automation is relatively stagnant. The annual ISA show has shrunk to a fraction of its former size; this year, it is just a technical conference. After a couple of years of recession, the automation majors have returned to profitability with some growth, but they remain cautious in an uncertain financial environment. Where will the industry be tomorrow? Let’s review and prognosticate.

PRESENT

Today, industrial automation has two large segments – distributed control systems (DCS) and programmable logic controllers (PLC). The rest of the industry is a scattered array of miscellaneous products and systems, sensors and actuators, all selling to the many different types of industries and applications termed “industrial.”

  • DCS.Honeywell introduced the original DCS – the TDC 2000 – in 1975. This was considered the fastest growing segment of the automation business – reportedly achieving $100 million in revenues within the first year. Other process controls leaders, like Foxboro, Taylor, Bailey and Yokogawa, quickly followed to make this a sizeable market segment.

The term “distributed” is something of a misnomer, because the system was really large clumps of mini-computers replacing large mainframes in giant central control rooms. Today, DCS has morphed into a variety of different shapes, sizes and form-factors, and this market segment has expanded to several billions of dollars worldwide.

  • PLC.The PLC was invented in 1968 by Dick Morley and others working for a consulting company called Bedford Associates, primarily associated with a relatively small Boston-based company called Modicon. From 1977 to the mid-1980s, Gould owned Modicon, and after some shuffling between German AEG and Schneider of France, the company is now owned by Schneider Electric.

The development of the PLC was in response to the needs of U.S. automotive manufacturers. The process for updating production facilities for the yearly model changeover was very time consuming and expensive, because electricians needed to individually rewire the hard-wired backplane. The PLC provided “soft” relay-ladder logic programming, easily understood and accomplished by the average electrician.

Odo Struggler was associated with Dick Morley in the development of the PLC, and Allen-Bradey, the company he was with, quickly rose to prominence through the growth of PLCs in the automobile business. Allen-Bradley, still a privately held company, was sold in 1985 for an estimated $1 billion US in cash to Rockwell International, an aerospace conglomerate. In 2001, Rockwell Automation was formed from the automation segments, and this company is still the market-share leader in North America.

Over the past three decades, the PLC has spread throughout the automation industry, and has almost become a commodity. The PLC market segment has grown to several billions of dollars worldwide, and the automotive industry is still one of the largest users.

  • Sensors and actuators.The other identifiable segment of industrial automation is sensors and actuators. There are many companies in the segment, each serving specialized niches and a broad array of diversified markets.

Perhaps the largest of the sensor companies is Rosemount, founded in 1956 with a focus on temperature sensors for the aerospace industry. In 1966, the com pany diversified its customer base by targeting the process industries with unique differential pressure flow sensors.

Rosemount’s success captured the attention of the conglomerates and, in August 1976, Emerson Electric acquired the company. Emerson also acquired Fisher Controls to become a process automation industry leader with products and services in all major categories.

  • Software.With the growth of PC-based systems to replace mini-computers, starting in the late 1970s and through the ’80s and ’90s, several innovative startups developed HMI software for PLCs and industrial I/O.

FUTURE

Today, automation growth is occurring primarily in international markets where new factories and plants are being built. In a tough, global environment, organic growth will not come easily, and the current crop of Top-10 automation majors will shrink by acquisitions and mergers. As China and India advance, expect one or both countries to make major automation acquisitions to enter the U.S. and European markets.

Today’s factories and process plants are still a mess of conventional wiring, and it’s an easy extrapolation to forecast the continued growth of industrial wireless. The inflection point will arrive when one of the automation majors recognizes that the high gross margins of conventional product pricing are producing only incremental revenues and profit growth. The companies that can yield low-cost industrial wireless will be rewarded with significant growth surges.

Today’s new products and services produce relatively small productivity gains by comparison and, therefore, produce only incremental growth. Substantial productivity increase with resultant revenue growth is overdue in the automation arena – look for it to break through in the next decade and quarter century.

Who knows – the new growth may come from completely new directions, such as complex-adaptive-systems, bio-chemical electronics or tiny nanotechnology sensors.

Happily, there are startups and visionaries who recognize the possibilities – and they will become the new leaders of tomorrow.


Why Automation?

In today’s fast-paced and technologically advanced world, it is of the utmost importance to achieve ever-increasing levels of plant efficiency and productivity while maintaining or increasing profits and quality.
