Definition of IO Link Protocol and Its Interface
IO Link is a peer-to-peer, serial digital communication protocol designed for periodic data exchange between sensors/actuators and controllers (PLCs). The IO Link protocol was first proposed by Siemens and has now become an international standard IEC 61131-9. With the advancement of Industry 4.0, the use of IO Link is becoming increasingly widespread. Today”s article will introduce the definition of the IO Link protocol and its interfaces.
Factory automation can be divided into execution layer, on-site layer, on-site control layer, workshop control layer, and management layer according to functional division. As shown in the following figure:
The execution layer includes various execution mechanisms (valves, pumps, motors, etc.) and sensors, which are the muscles and peripheral nerves of factory automation. They receive commands from the upper layer and complete specified actions.
The on-9662-810 Invensys Triconex system site layer includes various distributed IO9662-810 Invensys Triconex system systems, which are the central nervous system of factory automation. It conveys control instructions from the upper layer to the execution layer; And feedback the signals from the execution layer to the control layer, serving as the information center;
The on-site control layer includes various PLC systems, which are the brains of factory automation. It issues corresponding instructions and commands the execution layer to complete corresponding actions based on internal program requirements and signal feedback from the execution layer;
The workshop control layer (MES) and management layer communicate with various PLC systems at the management level to complete management tasks at the workshop and factory levels.
The IO Link protocol to be introduced in this article is a protocol that transfers data between the execution layer and the field layer. An IO Link system consists of the following components:
1) IO Link Master;
2) IO Link Device;
3) Non shielded 3-5 core standard cable;
4) Tools for configuring IO Link parameters;
The IO Link Master transfers data between the IO Link device and the PLC. It is usually a distributed IO module with IO Link connection channels on the module. The IO Link Device is connected to the channel of the IO Link Master through a cable, and the IO Link Master exchanges data with the PLC through a bus. As shown in the following figure:
Every IO Link device needs to be connected to a channel of the IO Link supervisor, so IO Link is a peer-to-peer communication protocol, not a bus protocol.
IO Link devices are divided into two types: sensors and actuators: sensors are usually the four pin interface of M12, and actuators are usually the five pin interface of M12.
According to IEC 60974-5-2, the definition of IO Link Device pins follows the following regulations:
1) Pin 1 (PIN1): 24V power supply positive pole;
2) Pin 3 (PIN3): 0V
3) Pin 4 (PIN4): IO Link communication or standard IO output;
The pin definition of the IO Link device is shown in the following figure:
Which types of equipment should PLC module manufacturers develop first?
We know that PLC, also known as programmable logic controller, collects variable data through various IOs to achieve the purpose of automated control. Therefore, developing PLC is largely about developing IO. However, with so many types of IO, which PLC module manufacturers should develop first? Let me share my opinion:
1. Digital input IO, including PNP and NPN digital input IO, counter input IO, etc.
2. Digital output IO, including PNP and NPN digital output IO, PWM pulse output IO, relay output IO, and so on.
3. Analog input IO, including current acquisition input IO, voltage acquisition input IO, temperature acquisition input IO, and so on. The current input IO can collect currents ranging from 0 to 20 milliamperes, while the voltage input IO can collect voltages ranging from negative 10V to positive 10V. Temperature acquisition IO includes thermocouples and thermal resistors.
4. The style of analog output IO is similar to that of analog input IO, but does not include temperature analog, mainly voltage and current type.

What is the role of distributed IO modules and what are their main applications in
The distributed IO module transmits status signals from the measurement and control field to various measurement and control fields for control. It is mainly used in the industrial field and can also be used for detection of equipment such as air conditioners and motors.
In distributed systems, there are important business data closely related to system operation, as well as data related to nodes, application services, and data services, which are crucial for the normal operation of clusters.
IO on general PLCs is usually closely followed by CPU units, but in order to facilitate connection and maintenance, the concept of distributed IO has been proposed in the industrial field. That is to say, the IO unit can be arranged far away from the PLC CPU unit and communicate through the network communication protocol of the device layer.
The distributed IO module is developed for detecting and implementing remote control of various types of standard analog and switch signals (frequency, pulse, or switch state signals) in the field of measurement and control.

Application of Data Acquisition IO Module in Thermal Power Plant System9662-810 Invensys Triconex system
The Ethernet IO module is a data acquisition and control device. It uses Ethernet as a communication method to transmit data from various industrial control sensors and actuators to computers or other devices for management and monitoring. As a modern energy supply base, thermal power plants need to widely apply various intelligent control technologies to improve operational efficiency, reduce costs, and improve safety. In this context, the application of barium rhenium Ethernet IO modules is particularly important.
In the application of thermal power plants, the main function of the barium rhenium Ethernet IO module is to achieve real-time monitoring and control of the production process. By connecting to various sensors and actuators, the barium rhenium Ethernet IO module can collect real-time environmental parameters, machine operation status, and other data of the thermal power plant. By analyzing and processing these data, commanders can understand the operation of the thermal power plant and make corresponding adjustments. Compared to traditional automatic control systems, the barium rhenium Ethernet IO module has the advantages of stronger flexibility, faster reaction speed, and higher accuracy, which can greatly improve the operational efficiency and reliability of thermal power plants.
The real-time monitoring and control of thermal power plants require many capabilities of barium rhenium Ethernet IO modules. Here are several common application scenarios:
Firstly, the barium rhenium module can monitor parameters such as gas flow and water flow in thermal power plants. These parameters are crucial for ensuring the normal operation of the thermal power plant. Once these parameters undergo abnormal changes, the DO channel can be connected to the barium rhenium Ethernet IO module, and the alarm signal will immediately sound to remind the command personnel to handle it. Meanwhile, due to the fact that the barium rhenium Ethernet IO module can collect these data in real-time and transmit it to the monitoring system for recording, it can provide better technical support for quality management in thermal power plants.
Secondly, the barium rhenium Ethernet IO module can also monitor the operating status of mechanical equipment in thermal power plants. This includes parameters such as temperature, pressure, vibration, etc. By monitoring and analyzing these parameters, the barium rhenium Ethernet IO module can detect machine equipment faults in a timely manner, thereby avoiding the expansion of losses. In addition, during machine equipment maintenance, historical data recorded by the barium rhenium Ethernet IO module can be used to develop more scientific and reasonable maintenance plans, reduce maintenance costs, and improve maintenance efficiency.
Finally, the barium rhenium Ethernet IO module can also help thermal power plants achieve distributed control. We can remotely control and monitor multiple areas of the thermal power plant by connecting multiple barium rhenium modules to a network. This not only reduces the on-site debugging of equipment, but also strengthens the evaluation of equipment reliability.
In summary, the barium rhenium Ethernet IO module has unique advantages in real-time monitoring and control of thermal power plants. It can help command personnel monitor machine data in real-time, discover abnormal information, take timely measures to avoid impacts, and improve production efficiency and safety.

Modify the watchdog time of the PROFINET IO device under 16 STEP7
3.2 Check if the installation of PROFINET IO communication equipment meets the specifications
Most cases of PROFINET IO communication interference problems are caused by equipment installation that does not comply with the installation specifications for PROFINET IO communication, such as incomplete shielding, unreliable grounding, and being too close to interference sources. Installation that meets the specifications can avoid communication failures caused by electromagnetic interference. You can refer to the following brief installation requirements for PROFINET:
1. Wiring of PROFINET 9662-810 Invensys Triconex system
In order to reduce the coupling of electric and magnetic fields, the larger the parallel distance between PROFINET and other power cable interference sources, the better. In accordance with IEC 61918, the minimum distance between PROFINET shielded cables and other cables can be referred to Table 1. PROFINET 9662-810 Invensys Triconex system can be wired together with other data cables, network cables, and shielded analog cables. If it is an unshielded power cable, the minimum distance is 200mm.
Comprehensive analysis of the principle and application skills of microcontroller IO port
IO port operation is the most basic and important knowledge in microcontroller practice. This article takes a long time to introduce the principles of IO ports. I also consulted a lot of materials to ensure the accuracy of the content, and spent a long time writing it. The principle of IO ports originally required a lot of in-depth knowledge, but here it has been simplified as much as possible for easy understanding. This will be of great help in solving various IO port related problems in the future.
The IO port equivalent model is my original method, which can effectively reduce the difficulty of understanding the internal structure of the IO port. And after consulting and confirming, this model is basically consistent with the actual working principle.
I mentioned a lot earlier, and many people may already be eager to actually operate microcontrollers. The IO port, as the main means of communication between the microcontroller and the outside world, is the most basic and important knowledge for microcontroller learning. Previously, we programmed and implemented an experiment to light up the LED at the IO port. This article will continue to introduce the relevant knowledge of the IO port.
In order to better learn the operation of IO ports, it is necessary to understand the internal structure and related concepts of IO ports. These knowledge are very helpful for subsequent learning, with a focus on understanding and no need to memorize them intentionally. If you don”t remember, just come back and take a look. If you use it too much, you will naturally remember.
We have said that the most accurate and effective way to understand a chip is to refer to official chip manuals and other materials. But for beginners of microcontrollers, it may be difficult to understand the chip manual directly, especially when they see a bunch of English, unfamiliar circuits, and terminology. If it were me, I would definitely be crazy. But here I still provide a picture taken from Atmel”s official “Atmel 8051 Microcontrollers Hardware Manual”.
The purpose of giving this picture is not to dampen everyone”s enthusiasm for learning, but to help everyone understand how the various microcontroller materials we have seen come from and whether they are accurate. All of these can be clarified through official information, which will be helpful for everyone to further learn something in the future.
Introduction to the Second Function
The above figure is the authoritative 51 microcontroller IO port structure diagram provided by the official. It can be seen that the internal structure of the four sets of IO ports of the microcontroller is different, because some IO ports have a secondary function, as mentioned in the introductory section.
Do you remember this pin diagram? The second function name of the IO port is marked in parentheses. Except for P1, each interface has a second function. When introducing the microcontroller system module, I mentioned that the 51 microcontroller has an interface for reserved extended memory, which is the second function of P0 and P1 in the figure (while also using pins such as 29 and 30). Because it is not widely used and involves in-depth knowledge, no specific research will be conducted. By the way, the AD0~AD7 we see here are actually used for parallel ports. The second function of the P3 port, including serial port, will be introduced in detail later.
The drawbacks of network IO and the advantages of multiplexing IO
In order to talk about multiplexing, of course, we still need to follow the trend and adopt a whiplash approach. First, we will talk about the drawbacks of traditional network IO and use the pull and step method to grasp the advantages of multiplexing IO.
For the convenience of understanding, all the following code is pseudo code, and it is sufficient to know the meaning it expresses.
Blocking IO
The server wrote the following code to handle the data of client connections and requests.
Listenfd=socket()// Open a network communication port
Bind (listenfd)// binding
Listen (listenfd)// Listening while (1){
Connfd=accept (listenfd)// Blocking connection establishment
Int n=read (connfd, buf)// Blocking read data
DoSomeThing (buf)// What to do with the data you read
Close (connfd)// Close the connection and wait for the next connection in a loop
}
This code will be executed with stumbling blocks, just like this.
It can be seen that the thread on the server is blocked in two places, one is the accept function and the other is the read function.
If we expand on the details of the read function again, we will find that it is blocked in two stages.
This is traditional blocking IO.
The overall process is shown in the following figure.
So, if the client of this connection continues to not send data, the server thread will continue to block on the read function and not return, nor will it be able to accept other client connections.
This is definitely not feasible.
Non blocking IO
To solve the above problem, the key is to modify the read function.
A clever approach is to create a new process or thread every time, call the read function, and perform business processing.
While (1){
Connfd=accept (listenfd)// Blocking connection establishment
Pthread_ Create (doWork)// Create a new thread
}
Void doWork(){
Int n=read (connfd, buf)// Blocking read data
DoSomeThing (buf)// What to do with the data you read
Close (connfd)// Close the connection and wait for the next connection in a loop
}
In this way, once a connection is established for a client, it can immediately wait for a new client connection without blocking the read request from the original client.
However, this is not called non blocking IO, it just uses multithreading to prevent the main thread from getting stuck in the read function and not going down. The read function provided by the operating system is still blocked.
So true non blocking IO cannot be achieved through our user layer tricks, but rather by imploring the operating system to provide us with a non blocking read function.
The effect of this read function is to immediately return an error value (-1) when no data arrives (reaches the network card and is copied to the kernel buffer), rather than waiting for blocking.
The operating system provides this feature by simply setting the file descriptor to non blocking before calling read.
Fcntl (connfd, F_SETFL, O_NONBLOCK);
Int n=read (connfd, buffer)= SUCCESS;
In this way, the user thread needs to loop through the call to read until the return value is not -1, and then start processing the business.
We noticed a detail here.
Non blocking read refers to the stage where data is non blocking before it reaches the network card, or before it reaches the network card but has not been copied to the kernel buffer.
When the data has reached the kernel buffer, calling the read function is still blocked and requires waiting for the data to be copied from the kernel buffer to the user buffer before returning.
The overall process is shown in the following figure
IO multiplexing
Creating a thread for each client can easily deplete the thread resources on the server side.
Of course, there is also a clever solution. After accepting each client connection, we can put the file descriptor (connfd) into an array.
Fdlist. add (connfd);
Then create a new thread to continuously traverse the array and call the non blocking read method for each element.
While (1){
For (fd “- fdlist){
If (read (fd)!=- 1){
DoSomeThing();
}
}
}
In this way, we successfully processed multiple client connections with one thread.
Do you think this means some multiplexing?
But this is just like using multithreading to transform blocked IO into seemingly non blocking IO. This traversal method is just a small trick that our users have come up with, and every time we encounter a read that returns -1, it is still a system call that wastes resources.
Making system calls in a while loop is not cost-effective, just like making rpc requests while working on distributed projects.
So, we still need to plead with the operating system boss to provide us with a function that has such an effect. We will pass a batch of file descriptors to the kernel through a system call, and the kernel layer will traverse them to truly solve this problem.
What are the types of integrated IO modules9662-810 Invensys Triconex system
For a programmable logic controller, IO fulfills the responsibilities of data acquisition and instruction output. What control objectives can a PLC achieve, and the quantity and type of IO are crucial. For general integrated PLCs, the number and types of IO interfaces are constant. Some friends may ask, what if you encounter a complex control project with insufficient IO ports in the PLC? Don”t worry, nowadays PLCs have communication interfaces that can be connected to other IO couplers to achieve IO expansion. So, what are the types of IO modules that we can integrate in our daily lives? Actually, it can be mainly divided into four categories, namely:
1. Digital signal acquisition IO can achieve discontinuous signal acquisition, and a typical IO type is a counter input IO module.

2. Digital output IO, which can send out command signals of digital quantities to control actuators, such as PWM IO, can send pulse signals to control servo motors and stepper motors. In addition to PWM IO, we often use relay output type IO.
3. After discussing digital IO, let”s talk about analog IO. Firstly, analog input IO includes voltage analog input IO, current analog input IO, temperature analog input IO, etc. They collect continuous signals.
4. Finally, there is the output type IO of analog quantity, mainly including voltage analog quantity output type IO and current analog quantity output type IO. Some friends may ask why there is no temperature this time, but there are relatively few applications, mainly based on voltage and current types.9662-810 Invensys Triconex system
Industrial automation solutions, starting with remote IO modules!
The remote IO module is mainly used for collecting analog and digital signals on industrial sites, and can also output analog and digital signals to control equipment. It is possible to expand the input and output ports of data processing equipment such as PLCs and collection instruments. For example, a PLC only has 10 analog input interfaces, but if 30 analog quantities need to be collected on site, remote IO expansion needs to be added.
Furthermore, due to the distance between the equipment and the main control PLC or industrial computer, RS-485 bus is usually used for transmission. There are also some factories with high levels of automation that use industrial Ethernet to control remote IO modules. In the past, when laying lines between equipment and cabinets, people had to connect them one by one, which greatly increased the cost of cables and construction time. Moreover, if the distance was relatively long, they also faced problems such as voltage attenuation. And with the remote IO module, it effectively solves this problem. If your cabinet is 200 meters away from the site and you do not use remote IO, then you need to lay out each signal line for 200 meters. Installing the remote IO module on site can save you a lot of cable costs and reduce the complexity of construction from a cost perspective.
Simply put, sometimes some IO is set up in the on-site device cluster, which can be connected to the PLC through a communication cable to send the signal to any place where it is needed, saving wiring and PLC”s own IO points. Sometimes, the logical “remote” is because the allowed number of “local IO” cannot meet the actual needs, and it needs to be connected to the “remote IO template”, depending on the actual situation.
In addition, the general cabinet room is located on the device site. But some control signals, such as emergency stop and bypass, are implemented in the control room, so remote IO modules need to be used to send these signals to the control system in the cabinet room.
Why use remote I/O?
1. Because in some industrial applications, it is impossible to install PLCs with local I/O modules near on-site equipment due to harsh environments.
2. When you want to place the I/O module near the field device to eliminate long multi-core cables, you can receive signals from distant sensors and send remote control signals to control valves, motors, and other final actuators. The signal can be transmitted at any distance using various transmission protocols such as Ethernet and Profibus through high-speed media such as twisted pair and fiber optic.
3. Multiple transmission protocols such as Ethernet and Profibus can be used to send signals at any distance on high-speed media such as twisted pair and fiber optic.
The barium rhenium technology MXXT remote IO module uses industrial grade components with a wide working voltage of DC9-36V, which can operate normally within the range of -20~70 ℃. It supports RS485/232 communication mode, and the communication protocol adopts standard Modbus TCP protocol, Modbus RTU over TCP protocol, and MQTT protocol. We strive to fully meet the needs of our customers with an electrical and mechanical system that is anti-interference, resistant to harsh environments, and compatible with general use. It has stable performance, reliable quality, short delivery time, and fast response.
Advantages of Barium Rhenium Remote I/O Module
1. It can be controlled by remote commands.
2. Save the cost of using industrial control computers and IO cards, and Ethernet I/O modules can be directly connected to the upper computer system;
3. Replacing 4-20mA signal transmission with 10/100MHz Ethernet transmission has improved transmission speed;
4. Replacing various instrument controller signal lines with an Ethernet cable reduces the attenuation of remote signal transmission;
5. The signal cable of the instrument controller only needs to be connected to the Ethernet I/O module, greatly reducing cable costs and wiring workload.
6. Convenient installation method. Rail installation, high reliability, strong anti-interference ability, and more convenient on-site installation.
