What role does the programmable logic controller play in automation?

A PLC is a digital electronic system that is equipped with programmable memory. The respective control instruction for the appropriate function can then be saved on this. Various types of machines and processes are then controlled via digital or analogue inputs and outputs.
Thanks to their great flexibility, PLCs are being used more and more frequently in many areas of industry and are replacing conventional connection-programmable controllers. Instead of hard-wired logic based on relay switches, where the control function can only be changed by laborious switching, these electronic components can be digitally programmed and take on complex control tasks in networked production processes of Industry 4.0.
Typical examples of the use of PLCs can be found in production plants, packaging machines, in the beverage and steel industries and also in the medical sector. But you also come across digital electrical controls in everyday life, for example in traffic light circuits, escalators, elevators, roller shutters and gate systems or even in heating systems.

Advantages of PLC

  • high flexibility and versatility
  • uncomplicated duplication and modification of the programming instead of cumbersome rewiring
  • simplified implementation of programming
  • less assembly effort
  • quick change of function
  • high reliability
  • low energy consumption
  • little need for space
  • Networking options with other devices and systems
  • Remote diagnosis and maintenance are possible

Programmable logic controllers only have a few disadvantages, which in individual cases speak for the use of conventional connection-programmable controllers: The costs for the components are comparatively high so the purchase of PLCs is not worthwhile for many small controllers. In addition, an appropriate technical infrastructure with digital devices and trained personnel are required for effective use. Acceptance and commissioning of systems can also be more complex since the program routines and programming have to be tested in addition to the machine components. Individual components such as safety circuits or device monitoring may become more complex.

How is a programmable logic controller structured?

The basic version of a PLC consists of a processor in the central module, signal inputs and outputs, an operating system and the interface.
The control is programmed via the application program on the computer or via a connected control panel. It is loaded onto the PLC via the interface and defines the switching of inputs and outputs. The actual operation then takes place independently of the computer and, thanks to its own PLC power supply, also autonomously.
Depending on the complexity, PLCs have a different number of analogue or digital inputs and outputs, which are linked to the machine or system via so-called sensors and actuators. At the inputs, for example, sensors such as pressure sensors, temperature or level sensors monitor the machine functions. The operating system evaluates the information collected, compares it with the parameters programmed by the user and sends the appropriate control signals to the outputs.
The actuators that control the functions are connected here. These can be contactors for switching on electric motors, electric valves for compressed air and hydraulics or drive control modules.

Functions of programmable logic controllers

PLCs can take on specific functions, such as:

  • link control,
  • Flow control,
  • as well as time, counting and arithmetic functions.

Cycle-oriented PLCs work strictly according to EVA, the basic principle of data processing with input, processing, output. The inputs are queried and control is passed to the user program. After transferring the control signals to the outputs, the process starts over.
Cyclic PLCs with interrupt processing report an alarm when the status of the connected sensor changes and then start an additional program loop adapted to the respective situation before continuing the main program.
Event-controlled PLCs process-specific pre-programmed tasks after a status change of the connected sensors.

Compatibility and accessories for networking

One of the biggest advantages of PLC is the cross-system networking with other devices and computers. Correct networking is not only important for new installations. Even PLCs based on older standards can be connected to modern devices during retrofitting using the appropriate PLC cables, plugs and adapters.
Most PLCs can be connected to a PC via a serial cable. Serial device servers are suitable for this, with which conventional serial components can be connected via LAN. Ethernet media converters connect different transmission media with each other in a compatible way. Common interfaces are RS-232 and RS-485 with DB-9 and DB-25 connectors.
However, PLC interfaces are not standardized, so depending on the device provider, other solutions are used in addition to standard serial cables, which you should find out about in advance or involve a specialist. In general, the design thus determines the requirements for the accessories for the respective PLC

The right equipment for your PLC

Your PLC gains in efficiency with the right additional equipment and can also be expanded with devices via the interface.

  • DIN rails: for optimal assembly.
  • Displays and monitors: for the direct display of operational data.
  • HMI touch panel: for multifunctional visualization, operation and diagnosis of machines and systems.
  • Smart gateway: Networking machines and systems intelligently in the IoT.

types of PLC

In terms of structure and functionality, a distinction is made between hard PLCs and soft PLCs as well as compact and slot PLCs.
Classic PLCs are hardware-based, hence their name Hard-PLC. They usually only include the most important control functions, but extensions for DIN rails and plug connections are quickly possible.
Soft PLCs take over the control in software form. They have their own operating system and often additional user software. However, they do not have their own CPU, but use the PC processor and have to share the processing power with the PC’s operating system and, if necessary, other applications. This can have an impact on the performance of the respective PLC when the load is high.
With a compact PLC, all components are housed together on a single circuit board in a single housing.
A slot PLC is used directly as a PCI plug-in card and for specific tasks such as storing production data. With these controllers, the PC replaces the PLC hardware. In contrast to a soft PLC, however, a slot PLC has a co-processor and its own operating system, with which it executes control tasks independently of the PC processor. Integrated connections enable access to decentralized actuators and sensors.

Modular PLC: A simple and individual solution for every machine system

Modular PLCs are not assemblies in the true sense but can be understood as a superordinate system. With modular controls, each individual functional component is housed in its own housing and on a separate control board. In this way, the PLC can be assembled individually using individual plug-in modules and easily expanded if required. An additional advantage is that in the event of a defect, only the respective assembly needs to be replaced and not the entire controller.

Features:

  • individual compilation of the required elements
  • Extension with the appropriate circuit board possible
  • for more complex regulation and control circuits

Programming languages ​​for PLC

Various programming languages ​​can be found in the controls:

  • ST – Structured Text
  • FBD – function block language
  • LAD – Ladder Diagram
  • IL – Instruction List
  • SCL—Structured Control Language

FBD is popular with PLC beginners because it works with drag & drop and the behaviour of inputs and outputs is easy to understand. Sophisticated programming can be implemented with SCL. ST and IL are text-based, the other three graphical.

Automation | trends and perspectives

Digital networking via the Internet of Things is currently one of the megatrends. In addition, interdisciplinary and thinking across industry boundaries are required – especially in automation. New technologies can only develop their full potential with the help of a comprehensive process understanding.

Automation

With regard to Industry 4.0, the theory is increasingly followed by action. Many experts are convinced that further coordination and bundled activities in the industry will only set additional changes in motion. Dr Attila Bilgic, Managing Director and CTO (Chief Technology Officer) of the Krohne Group, Duisburg. “The industry is struggling to initiate disruptive approaches. However, we find it even more difficult to implement them. “However, the evolutionary development of processes works well, Figure 1:” We are able to further improve things that we are good at. ” Bilgictherefore recommends thinking outside the box about basic core business processes. In his opinion, one risk is missing out on new opportunities – with the effect that others close the gap and, as a result, fill the entire value chain. Real winners will recognize the opportunities that Industry 4.0 offers, Figure 2 – and seize them.

Anomaly detection to defend against cyber attacks

The diverse opportunities of Industry 4.0 are increasingly faced with questions of information security: How can the confidentiality, integrity and availability of industrial devices and systems be guaranteed? The “AnoKo” research project (Koramis GmbH, Potsdam; Zema – Center for Mechatronics and Automation Technology, Saarbrücken) aims to detect unauthorized access or interference in production systems. This is to be achieved by analyzing the industrial communication system of a production plant for deviations at defined time intervals. To get physical and Online training in all Automation courses click here

The anomaly detection system, which was further developed in the AnoKo project, enables operators to protect their production facilities more comprehensively from attacks. To this end, design analysis of selected industrial communication protocols is carried out first. On this basis, observation and evaluation criteria are defined and implemented. “With the help of the project results, anomaly detection systems can be more easily adapted to specific industrial protocols and evaluated under real conditions. These systems can then be subsequently integrated into existing systems or used as a basic platform for the development of future Industry 4.0 applications, ”explains Dipl.-Ing. Heiko Adamczyk , Business Development, Security and Industry 4.0 at Koramis.

Use data analysis for better user guidance

Analyze data and use it for optimization: This megatrend is not only reflected in security issues. A key question is how, thanks to integrated data analysis and fusion, improved user guidance of operator assistance systems is possible. They can help reduce costs caused by defective parts and processes in assembly. The crucial question in this process is which data can be used for analysis, how they are related to one another and how a corresponding recommendation for action can be obtained. Dipl.-Ing. Benno Lüdicke , Dipl.-Inf. Christoph Legat and David Renaudfrom Assystem, Paris / F. One question is, for example, how data analyzes can be used to reliably identify defective parts and thus avoid them. To do this, it is first necessary to reliably record the process parameters. Using the data analysis, the deviation can then be quantified and qualified.

Predictive maintenance in the context of Industry 4.0

Automating maintenance processes, making machine maintenance more efficient and finally achieving predictive maintenance: How this plan can be achieved step by step is shown by a current research project by Sybit GmbH, Radolfzell am Bodensee, in cooperation with the Swiss technology group Bühler, headquartered in Uzwil. Their machines are in use all over the world. The entire maintenance process is correspondingly complex.
In the first step, AR (Augmented Reality) glasses are used to reduce travel and time expenditure for service technicians. “The service specialist can inspect machines worldwide from his office and also guide the machine operator ‘on site’ with maintenance steps,” explains Sybit research director Dr.-Ing. Jesko Elsner. This forms the start of efficient remote diagnosis that saves money, time and effort. Successful remote maintenance is possible through the combination of human expertise, visual perception through the AR glasses and the data that the sensors of the machine continuously deliver. Many problems can already be solved this way. In addition, remote diagnosis makes it much more efficient to identify any need for spare parts and to send the required parts faster.

The project goes well beyond the individual maintenance case: data from various maintenance situations are collected and automatically evaluated by the system. This results in a pattern of frequent maintenance cases to which those responsible can react even faster and more systematically in the future – right up to predictive maintenance that predicts necessary maintenance intervals even more precisely and thus further shortens unplanned downtimes. “This could result in completely new business models for machine manufacturers in the future, for example in the combination of maintenance service and guaranteed production figures instead of just selling a single machine,” explains Dr. Elsner .

Automation Congress analyzes the trends

The specialist congress in the Kongresshaus Baden-Baden provided insights into these and other topics. The focal points continued to include efficiency increases in the planning of automated systems, the planning of the communication infrastructure for future automation systems and the role of Industry 4.0 and the “digital twin” in the life cycle of a system.

SCADA System

SCADA is the abbreviation for “Supervisory Control and Data Acquisition”. This word is currently widely used by industrialists, but it is still little known by most of us.

What is that? When should you use SCADA systems? Where can you use them? Etc.

Many of us want concrete answers to these questions. That’s why we’re going to walk you through everything there is to know about this topic in detail.

SCADA system
SCADA system

What exactly does the term SCADA mean?

SCADA is an acronym for four letters: Data Acquisition and Control System.

In fact, it refers to a category of software dedicated to controlling industrial processes and collecting data in real-time at remote sites. SCADA systems can be used to maintain control over your equipment, industrial processes, and to optimize their operating conditions.

A typical SCADA system is made up of transmitters, a remote terminal unit (RTU), communication protocols allowing communication between the servers and RTU transmitters, a data server for archiving data and supply the human-machine interfaces (HMI). HMIs are user interfaces that can connect the operator to the control device of an industrial system.

If a SCADA automation infrastructure is properly designed, it should enable companies to:

  • Better respond to operational questions
  • Do more, do better and at a lower cost
  • Increase the availability and life cycle of their equipment
  • Improve the performance and reduce the maintenance costs of their equipment
  • Etc.

Now here is an overview of the evolution of SCADA systems.

The four types of SCADA systems

There are different types of systems that can be considered SCADA architectures.

They improve as technologies evolve.

First-generation: monolithic SCADA systems

Previously, manufacturers have used minicomputers to optimize their processes and equipment.

Back in the day, monolithic SCADA systems were very popular and did not use common network services. The systems were therefore independent, that is, one computer could not connect to other systems. The remote sites were connected through a backup mainframe system.

This ensured the redundancy of the first generation SCADA system. The monolithic concept was mainly used in the event of the failure of the primary mainframe system. The use of this older form of SCADA system was limited to monitoring system sensors as well as signalling

any operation if programmed alarm levels were exceeded.

Second generation: distributed SCADA systems

For this second generation of SCADA systems, the sharing of control functions is distributed among several systems connected to each other via a local area network (LAN). They were therefore called distributed SCADA systems.

Individual stations were used to share real-time information, process orders and perform monitoring tasks to raise alarm levels in the event of problems. What differentiates them from older systems is the reduced cost and size of the station.

However, network protocols were not standardized, and the security of installations could only be determined by very few people other than developers. In other words, the security of the second generation SCADA installation has been ignored.

Third generation: networked SCADA systems

Current SCADA systems are now networked and can communicate over a Wide Area Network (WAN) over data lines or by telephone.

These systems typically use Ethernet or fibre-optic connections to transmit data between nodes. They also use Programmable Logic Controllers (PLCs) to monitor or adjust routine signalling systems for critical decisions.

While the first and second generation SCADA systems were limited to single networks or buildings, the third generation SCADA uses the Internet, often implying a security concern.

Fourth generation: SCADA 4.0 systems based on the Internet of Things (IoT)

The emergence of the fourth generation of SCADA systems has drastically reduced the cost of infrastructure through the adoption of IoT technology and cloud computing. System integration and maintenance is therefore very easy compared to previous systems. The latest technological advancements in SCADA systems now allow real-time status reporting, the use of more complex control algorithms, and the increased security of sensitive information in large enterprises. In addition, these systems can be implemented on traditional PLCs.

SCADA: how does it work?

As already mentioned, SCADA is a term used to refer to centralized systems designed to control and monitor an entire industrial site or complex equipment spread over large areas. Almost all control actions are performed automatically by PLCs or RTUs.

Take the example of an industrial water supply process: the PLC can in this case-control the flow of cooling water and the SCADA system can record and display all changes related to the alarm conditions in case of variations. or loss of flow, a significant rise in temperature, etc.

The data is collected at an application programming interface or an RTU. They include condition reports of monitored equipment as well as meter readings. They will then be formatted so that the control room operator can take the necessary steps to add or override the normal PLC commands (RTU), using a Human Machine Interface (HMI).

Thus, the RTU can connect to the physical equipment and convert all the electrical signals coming from that equipment into digital values, such as the open or closed state of a valve or switch, flow or pressure measurements. pressure, current-voltage, etc.

In this way, the RTU can automatically control the equipment or allow an operator to do so, for example by closing or opening a valve or switch, or by adjusting the speed of the pump.

SCADA: the human-machine interface

It is worth mentioning what the HMI stands for. This is a device that delivers the data processed by the RTU to the human operator. The latter can therefore use it to control industrial processes.

The HMI is linked to the databases of the SCADA system, which allows it to display diagnostic data, management information, logistics information, detailed diagrams of the operation of a given machine or sensor, maintenance procedures or troubleshooting guides.

The operator can therefore have, for example, the image of a pump connected to the piping. The HMI provides him with a diagram that shows whether this pump is working or not, or whether the amount of liquid pumped through the piping is within the operating conditions of the equipment at any given time. In the event of an adjustment, for example, when a pump is stopped, the HMI software will instantly show the decrease in fluid flow in the pipes.

Note that the block diagrams provided by the HMI may be in the form of digital photographs of process equipment and be accompanied by animated symbols (schematic symbols, line graphics, etc.). As a result, representations can be as simple as an on-screen traffic light network, representing the status of the traffic light in real-time in a given area. They can also be very complex, such as the multi-projector display showing the position of all trains on a large railway network.

Generally speaking, SCADA systems are used in alarm systems, which means that there are only two digital status points. On the one hand, when the alarm’s requirements are met, it activates. If necessary, it remains in its state. In other words, they look like the fuel level alarm system in your car. When the tank is almost empty, the alarm activates automatically in the form of a light signal.

As for SCADA systems, company operators and managers are notified by text messages and emails sent with the alarm activated. But in addition, they can view graphical trends, manage the various parameters relating to the configuration of their equipment, etc.

In which areas can SCADA systems be used?

All over the world, SCADA systems are used in various applications and in all industries.

Production, transport, distribution of gas and electricity

In these different sectors, utilities use, for example, SCADA systems to detect current flow and line voltage, to monitor the operation of circuit breakers, etc. These tools can also assist in the monitoring and control of pipelines, the remote control of storage, pumping or refinery sites, or the control of the distribution of electrical energy from various energy sources such as coal, nuclear or gas.

Building

Building managers often use SCADA systems to control heating, air conditioning, refrigeration equipment and lighting units.

Manufacturing

In manufacturing industries, SCADA systems are used to manage manufacturing parts lists, optimize industrial automation, and monitor quality control systems and processes.

Public transport

As mentioned above, public transport services can use SCADA systems to regulate the electricity of subways, streetcars and trolleybuses.

In other cases, it is used to automate traffic lights in railway systems, to track and locate buses and trains, to control barriers at railway level crossings or to control the flow of traffic, by detecting, for example, fires that are out of order

Water and sanitation networks

Although not often covered in the media, SCADA systems are indeed used in the sanitation industry. The state and municipalities can use these systems to monitor and control water treatment centres, collection facilities and treated water disposal under the best conditions. Of course, other industries use this kind of software, such as those involved in agriculture and irrigation, pharmaceutical production, and telecommunications, among others.

How to choose your SCADA software?

Do you want to acquire this kind of tool, but you do not know how to choose? To help you, here are some criteria you should consider: compatibility, cost, included drivers, performance and security of SCADA.

Apart from that, you should also pay attention to the technical service that accompanies your software and its possibilities of adaptation with the technological tools of the future. In any case, you should always bet on the ease of deployment and use of your SCADA system.

Compatibility

Your SCADA system must be compatible with any operating system. So you can run it on Windows Vista, Windows 7, Windows Server Editions Mac or Linux.

Cost: a decisive choice criterion

Of course, like any other software, the cost of acquiring, deploying, maintaining and upgrading it is critical. Its price must therefore include all these elements. In this way, you will avoid purchasing additional functions, for example, to be able to add them to your system.

Technical support

This element is often what differentiates one SCADA system from another. Data collection and analysis software, even if it comes at low prices, that does not offer good support will never be able to compete with others.

Choose a scalable solution

Your SCADA system must be very versatile in order for it to operate in different environments. If you are responsible for choosing a SCADA system for your business, you should consider how your needs will change over the next 15 years – the average life cycle of SCADA systems. All of this seems easier said than done. Here is why, if in doubt, you should call a specialist in the field.

SCADA security issues

Some manufacturers are reluctant to adopt the latest generation SCADA systems, mistakenly believing that they are vulnerable to cybercrime attacks. Some of them also believe that SCADA networks that are physically secure and disconnected from the Internet are secure enough. In reality, as SCADA systems can be used for monitoring and controlling strategic processes like water distribution, traffic light management, electricity distribution, gas transmission, etc., it is well logical to ask the question about possible hacks of the system and their consequences. To be honest, there are two major threats when it comes to SCADA systems. The first is unauthorized access to the software, carried out intentionally by human or inadvertent changes, virus infections and any other problem that can affect the controlling machine.

The second threat relates to packet access to network segments hosting SCADA systems. In many cases, vendors provide little security to the packet control protocol. So anyone who sends packets to the system could control it. Still, it is very easy to secure the system. For example, users can use VPN security to ensure sufficient protection. SCADA providers can also avoid these risks by setting up industrial firewalls specifically dedicated to TCP / IP-based SCADA networks. In addition, whitelist solutions can be implemented and they are able to prevent unauthorized modifications of applications.

Clarity, a solution that brings intelligence to your SCADA systems

The result of long years of research and development, Clarity is an interface provided by Crowley Carbon that allows companies to modernize their industrial processes. Built from the ground up and cloud-based, this software provides its users with an unmatched platform that brings intelligence to their SCADA systems. Thus, they can reduce the energy consumption of their businesses, increase uptime by reducing the downtime of their equipment, while improving the performance of their processes. Clarity provides remote visibility of data points, which enables manufacturers to monitor, compare, measure and improve the energy efficiency of their plant with exceptional reporting. To do this, users can use Clarity and optimize their processes in three steps.

Step 1: Modeling

  • Definition and modelling of critical processes,
  • Creation of “Digital Twins” or “Digital Twins“.

Step 2: Analyze the data

  • Overlay of data collected in real-time on the Digital Twins.
  • Generation of information from data mining

Step 3: Implement the solutions

Use of information to upgrade your equipment and processes.
Good to know: Digital twins are a digital replication of an asset, supply chain or process. They are very reliable compared to models and simulations that have already been used by companies, as they work in parallel with the real process. Digital Twins improve the performance of companies by increasing their creativity, their innovative strength, the efficiency of their teams and by offering the best returns as well as a stronger competitive position.

Why choose Clarity?

Energy Savings: This interface helps you measure and compare energy savings through comprehensive energy management and optimization system. Understanding of processes: In-depth knowledge of your metering systems, SCADA systems, programmable logic controllers, production systems, etc. is essential to shedding light on the performance of your processes in real-time. Thus, you can take the necessary measures to reduce your costs and improve the yields of your equipment and processes. Reliability: Clarity allows you to predict future failures of your equipment. So you can act before they happen and therefore reduce unplanned downtime. This allows you to maximize the profitability of your plant.

What about interface security?

When it comes to software and data security, Clarity developers recognize that the confidentiality, integrity and availability of user and customer data are essential. With a progressive approach to cloud security, they have implemented the most reliable data protection systems on the market. These systems allow them to continuously monitor applications and processes and then optimize them to meet growing demands and cybercrime risks.

Conclusion

You don’t have to be an expert to know that technology changes at a rapid rate. Manufacturers are also aware of this fact, which forces them to determine the best course of action to adopt in order to optimize their operational processes and increase their return on investment. One of the best ways to achieve this goal is to adopt reliable and scalable SCADA software. This technology is currently used in many industries, thanks to its ease of management and its many advantages. Clarity is a complete software that uses the SCADA system to enable manufacturers to improve the energy efficiency of their businesses. This system allows you to control and optimize many processes involved in the operation of your factory business and increase its profitability

What can a PLC do?  Why do we use them?

  • The CPU regulates the program, data storage and data exchange with I / O modules.
  • Input and output modules are the means of exchanging data between field devices and CPUs. Indicates to the CPU the exact status of the field devices and also acts as a tool to control them.
  • A programming device is a computer loaded with programming software that allows a user to create, transfer, and make changes to HMI software.
  • Memory provides storage media for the HMI program as well as for different data.

The concept of PLC 

” PLC ” which means ” Programmable Logic Controller “, is clear. The word “programmable” differentiates it from the conventional logic of the relay. It can be easily programmed or changed according to the application requirement. The HMI also outweighed the risk of wiring change.

What can a PLC do? Why do we use them? (in the photo: SIEMENS Simatic S7-1500, credit: fully integratedautomation.com)

The PLC as a unit consists of a processor to perform the control action on the field data provided by the input and output units. In a programming device, the PLC control logic is first developed and then transferred to the PLC.

So what can a PLC do?

  • It can perform retransmission switching tasks.
  • It can perform counting, calculation and comparison of analogue process values.
  • Provides flexibility to modify control logic, whenever needed, in the shortest amount of time.
  • Responds to changes in process parameters within fractions of a second.
  • Improves the reliability of the overall control system.
  • It is cost-effective to control complex systems.
  • It aims to pull simpler and faster
  • Can work with the help of HMI (Human-Machine Interface) compute.

The following is an example of ABB programmed AC500 logic controllers.

Basic component diagram

Figure 1 shows the basic diagram of a common PLC system.

Complete PLC diagram

As shown in the figure above, the heart of the “PLC” is in the centre, ie the heart of the Processor or CPU (central processing unit).

  • The CPU regulates the SCADA program, data storage and data exchange with I / O modules.
  • Input and output modules are the means of exchanging data between field devices and CPUs. Indicates to the CPU the exact status of the field devices and also acts as a tool to control them.
  • A programming device is a computer loaded with programming software that allows a user to create, transfer, and make changes to PLC software.
  • Memory provides storage media for the HMI program as well as for different data.

PLC system size

They are usually sorted by size:

  • A small system is one with less than 500 analogue and digital I / Os.
  • An intermediate system has I / Os ranging from 500 to 5,000.
  • A system with over 5,000 I / O is considered large.

Components of the PLC system

CPU or processor: The main processor (central processing unit or CPU) is a microprocessor-based system that runs the control program after reading the status of the field inputs and then sends commands to the field outputs.

I / O Section: The I / O modules act as the “Real Data Interface” between the field and the CPU. It knows the real status of the field devices and controls the field devices through the relevant input/output cards.

Programming device: A CPU card can be connected to a programming device via a communication link via a programming port on the CPU.

Operating station: A operating station is commonly used to provide an “operating window” to the process. It is usually a separate device (generally a PC), loaded with HMI (Human Machine Software).

PLC settings

There are two basic configurations that commercial manufacturers offer:

  1. Stable configuration
Stable PLC configuration

2. Modular configuration

How to use Mitsubishi PLC jump instruction?

the conditional jump instruction shows that the code, mnemonic, operand and program steps of the instruction are shown in Table 8-3. Operand instruction name instruction code digits mnemonic D (·) program step condition jump FNC00 (16) CJCJ (P) P0~P127 P63 is END, without jump mark CJ and CJ(P)~3 step label P~ The use of the 1-step jump instruction in the ladder diagram is shown in the figure. The jump pointers P8 and P9 in the figure correspond to two jump instructions, CJP8 and CJP9, respectively. The meaning of the execution of the jump instruction is: when the jump condition (X000=ON) is met, the PLC does not execute the program between the jump instruction and the jump pointer Pn in each scan cycle but jumps to the pointer Pn It is executed in the block of entry until the jump condition is not met, the jump stops.

How to use Mitsubishi PLC jump instruction CJ P0?

P0 is just the pointer number, and the driving condition is closed to jump to the designated number to execute this part of the program.
  The conditional jump instruction CJ is used to skip a certain part of the sequence program to shorten the operation cycle and control the flow of the program. The mnemonic of the instruction is CJ, the instruction code is FNC00, and the operating elements are P0-P127, and its program steps The situation is that CJ is 3 steps, and the label P is 1 step.
  If the timer and counter are working at the beginning of the skipped step, it will stop timing and counting during the skipped step, and continue to work when the condition of the CJ instruction becomes unsatisfactory. The processing of the high-speed counter is independent of the main program, and its work is not affected by the skip. If the CJ instruction is driven by the moving and closing contacts of the M8000, the conditional jump becomes an unconditional jump.
 Extended information:
  Precautions for the use of Mitsubishi plc jump instructions:
  1. JCP instruction is expressed as pulse execution mode.
  2. A label can only appear once in a program, otherwise, an error will occur.
  3. During the execution of the jump, even if the driving conditions of the skipped program are changed, the coil (or result) remains in the state before the jump, because the program is not executed at all during the jump.
  4. If the reset (RST) instruction of the totalizer timer and counter is outside the jump area, even if the coil is jumped, the reset is still valid.

The difference between Mitsubishi plc interrupt instruction and interlocking

The difference between Mitsubishi plc interrupt instruction and interlocking
The jump instruction means that the program jumps to the marked position to continue execution, and the skipped part is not executed
To call a subroutine is to jump from the current to the subroutine segment, and return to continue executing the next program of CALL after execution.
The interrupt instruction is similar to the process of executing a subroutine. Both jump, execute and return to the breakpoint to continue execution, but it may be executed anywhere in the program (triggered by external conditions), and the subroutine call is only when the program runs to a specific location. implement.

Who has the PLC jump instruction ladder diagram?

Transfer instructions are also called transfer instructions. After using the jump instruction in the program, the system can choose to execute different program segments according to different conditions. The jump instruction is composed of the jump instruction JMP and the label instruction LBL. The JMP instruction is programmed in the form of a coil in the ladder diagram.
When the control conditions are met, the jump instruction JMP n is executed, and the program is transferred to the destination location specified by the label n. The position is determined by the label instruction LBL n. The range of n is 0-255.
Pay attention to the following issues when using jump instructions.
1) JMP and LBL instructions must be in the same block, such as the same main program, subprogram or interrupt program. That is, it is not possible to jump from one block to another block.
2) After executing the jump instruction, the counter in the program segment between JMP and LBL stops counting, and its count value and counter bit status remain unchanged.
3) After the jump instruction is executed, the state of output Q, bit memory M and sequence control relay S in the block between JMP and LBL remains unchanged.
4) After executing the jump instruction, in the program segment between JMP and LBL, the timer with a resolution of 1 ms and 10 ms keeps the original working state and function; the timer with a resolution of 100 ms stops working. The value remains unchanged at the time of the jump.
  
The working process of this example is as follows.
1) When the input terminal I0.1 is turned on, the jump instruction JMP is executed, and the program skips network 2 and transfers to the position labelled 6 for execution.
2) For the skipped network 2, its output Q0.0 state remains unchanged from the state before the jump.

How to use Plc jump instruction?

Since you did not specify which brand of PLC, I will take S7-300 as an example directly. When you use the STL language for programming, jump instructions include JU, JL, TC, TCN, JCB, JNB, etc., and JU is unconditional. Jump, JL multi-branch jump, JC is RLO=1 is jumping waiting, in fact, there is help in the programming software to directly check which is more clear, and there are examples

In Mitsubishi PLC programming, what is the difference between

Subroutines help you divide the program into blocks. The instructions used in the main program determine the execution status of the specific subroutine. When the main program calls and executes the subprogram, the subprogram executes all instructions until the end. Then, the system returns control to the main program in the calling subprogram network.
Subroutines are used to segment and divide the program into smaller, more manageable blocks. You can take advantage of this when debugging and maintenance in the program. By using smaller program blocks, these areas and the entire program can be easily debugged and trouble-shooted. Calling the program blocks only when needed, the PLC can be used more effectively, because all the program blocks may not need to perform each scan.
Finally, if the subroutine only references parameters and local memory, the subroutine can be moved. In order to move subroutines, avoid using any global variables/symbols (I, Q, M, SM, AI, AQ, V, T, C, S, absolute addresses in AC memory). If the subroutine has no call parameters (IN, OUT, or IN_OUT) or only uses local variables in the L memory, you can export the subroutine and import it into another project.
To use a subroutine in a program, you must perform the following three tasks:
Establish subroutines
Define parameters in the local variable table of the subroutine (if any)
Call the subroutine from the appropriate POU (from the main program or another subroutine)
When the subroutine is called, the entire logic stack is saved, the top of the stack is set to one, all other stack positions are set to zero, and control is transferred to the calling subroutine. When the subroutine is completed, the stack is restored to the value retained at the call point, and control returns to the calling routine.
The subroutine and the calling routine share the accumulator. Due to the use of subroutines, no save or restore operation is performed on the accumulator.
Call subroutine with parameters
The subroutine may contain parameters for handover. The parameters are defined in the local variable table of the subroutine. The parameter must have a symbolic name (up to 23 characters), a variable type, and a data type. 16 parameters can be transferred to the subprogram or 16 parameters can be transferred from the subprogram.
The variable type field in the local variable table defines whether the parameter is transferred to the subroutine (IN), transferred to or transferred out of the subroutine (IN_OUT) or transferred out of the subroutine (OUT). The following table shows the parameter types of the subroutine. To add a parameter item, place the cursor on the variable type field of the type you want to add (IN,
IN_OUT or OUT). Right-click the unipolar mouse to get the options menu. Select the “Insert” option, and then select the “Next row” option. Another parameter entry of the selected type will be displayed below the current entry.
The jump to label (JMP) instruction performs branch operations on the specified label (n) in the program. When the jump is accepted, the top value of the stack is always logic 1. The label (LBL) instruction marks the location of the jump destination (n). You can use the “jump” instruction in the main program, subroutine or interrupt routine. The “jump” and it’s corresponding “label” instructions must always be located in the same code segment (main program, subroutine or interrupt routine). You cannot jump from the main program to a label in a subprogram or interrupt routine. Similarly, you cannot jump from a subprogram or interrupt routine to a label outside the subprogram or interrupt routine. You can use the “jump” instruction in the SCR segment, but the corresponding “label” instruction must be located in the same SCR segment.
The Enable Interrupt (ENI) instruction globally enables all additional interrupt event processes. The Disable Interrupt (DISI) instruction globally prohibits all interrupt event processes. When transitioning to RUN mode, the interrupt is disabled at the beginning. Once you enter the RUN mode, you can enable all interrupt processes by executing the global interrupt enable instruction. Executing the interrupt prohibition instruction will prohibit processing interrupts, but the active interrupt event will continue to be queued for waiting

What is the difference between jump instruction and interrupt?

Jump instruction, you will not jump until it is executed. That is, it will be executed only after the scanning period has been scanned, just like your mother told you not to play games to buy food, you have to wait until the game is over.
And interruption, when an interruption occurs, stop the current scan for interruption processing, just like your girlfriend, let you come over now, even if you are in the game.

What is the function and role of the jump instruction in PLC?

This is basically the case.
Jump instruction, jump to the pointer position for execution, execute to the return instruction and then return to the next jump instruction to continue execution.
There are many types of interrupts, some of which are not scanned. Anyway, always continue to execute the next program after execution.

Timer in a PLC

Timer in PLC
Timer in PLC

Timer in a PLC program, for example, to trigger a time-controlled action. This can be, for example, a cylinder that should remain in the end position for several seconds before it is moved back again. Or an alarm light that should light up for several seconds. For such actions, you need timers with which time-controlled functions can be programmed. According to the programming standard 61131-3, four-time functions have been defined. These are:
Real-time clock
Function block for generating a pulse (TP)
Function block for the switch-on delay (TON)
Function block for the switch-off delay (TOF)

Overview of standard function blocks according to DIN EN 61131-3

  • Explanation of the operands:
  • IN = start condition, signal change from 0 to 1
  • PT = time preset
  • Q = status of time
  • ET = current time value

Time functions in the programming software

The four-time functions specified in the programming standard 61131-3 did not meet the demands of many programmers. For example, the time functions according to 61131-3 do not see any possibility of resetting a timer. This is why many manufacturers of PLC programming software have their own time functions with extended functionality. The following extended time functions are included in Step7:

  • Time function SA: switch-off delay
  • Time function SE: switch-on delay
  • Time function SI: impulse
  • Time function SS: Retentive switch-on delay
  • Time function SV: Extended pulse

Overview of the designations and pulse diagrams of time functions in Step7

If you want to use the three standard time functions TP, TON and TOF in Step7, you have to do this by calling the following system function blocks:

  • SFB3: For TP
  • SFB4: For TON
  • SFB5: For TOF

If these system function blocks are used, an instance data block must be assigned for each of them so that the necessary data is available as static local variables. If, on the other hand, the company-specific time functions are used, a time operand, e.g. T1, must be used instead of an instance data block. The time operands can also be defined globally in the symbol table.
The company-specific time functions in Step7 are easier to handle and have a larger range of functions. For example, every time function has a reset input. S5TIME is used as the data type for the time.
How the PLC implements the timing internally is irrelevant for the programmer. You just have to know that an internal clock generator provides counting impulses through which the time runs backwards. So if you set a time on a timer, then the counter is preset. The time runs down due to the counting pulses and the counter receives the count 0 when the time has elapsed.
The cyclical processing of the program is not affected because the time function is updated asynchronously to the program processing. As a result, timers have a different value at the start of the cycle than at the end of the cycle. To get complete physical and online training in Timer in a PLC chick here

Use of the real-time clock

A clock, either as a real-time clock or a software clock, has been implemented in all CPUs of the S7-300 and S7-400 series. An integrated clock can be used in two different ways:
Master: In this case, the integrated clock acts as the master clock.
Slave: In this case, the clock plays a subordinate role of a master and is synchronized with the master.
With an integrated clock, time-of-day alarms or operating hours counters can be implemented if required. The watch shows the following values:
Time, at least with the display of seconds
date
weekday
Whether the milliseconds are also displayed depends on the CPU used. Here you have to look in the reference manual of the device to find out more.
The date and time can be set by the programmer himself. To do this, you need to call up the following system function and in the PLC program:
SFC0 (SET_CLK)
Alternatively, you can do this via the programming device menu. To do this, go online in the programming device, open the target system menu and select Set time from the menu. You can either take the time directly from the programming device / PC or enter a date and time yourself.
In this way, you can also read out the current time and date of the CPU. The system function SFC1 (READ_CLK) is used to read out the date and time directly in the program.

Programmable logic controller (PLC)

PLC Programmable logic controller
PLC Programmable logic controller

Programmable logic controller
A programmable logic controller q ( PLC ), or programmable controller is a device that replaces the conventional automation table all auxiliary relays, time, the counters of an industrial computer digital q having become resistant and adapted for controlling production processes, such as production lines, or robotic devices, or any activity that requires high control reliability and ease of programming and fault diagnosis process.

First developed in the automotive industry to provide flexible, durable and easily programmable controllers to replace hard relay wiring and timers. They have since been widely adopted as highly reliable automation controllers, and are suitable for harsh environments. A PLC Programmable logic controller is an example of a “hard” system operating in real-time as the results must be generated in response to the system input conditions within a limited time, otherwise, there will be unintentional operation.
They can be designed for multiple digital and analogue I / O settings, extended temperature fluctuations, electrical noise immunity, and shock and vibration resistance. Programs to control the operation of the machine are usually stored in battery-backed-up or non-volatile memory.

To get Physical and Online Training in PLC by experts instructors of Automation Industry

The PLC was born in the US automotive industry. Before PLC, relays, sequins, cam timers, percussion timers, and closed-loop controllers were regulated for control, sequencing, and logic for the safe construction of cars. Of these they could number in the hundreds or even thousands, the process of updating these installations was very time consuming and costly, and they also needed electricians to connect each relay and change their functional characteristics.

When digital computers became available, general-purpose programmable devices were used to test sequential and combinational logic in industrial processes. However, these early computers required special programmers and strict environmental controls for temperature, cleanliness, and power quality. To meet these challenges, the PLC was developed with many key features. It would not tolerate the shop-floor environment, would support bit-format input and output in an easily scalable way, would not require years of training to use, and would allow the operation to be monitored. Since many industrial processes have schedules that can be easily addressed with response times in milliseconds, in modern (fast, small, reliable) electronics greatly facilitate the building of reliable controllers, and performance could be exchanged for their reliability.
