What are the advantages of Ethernet remote IO modules that can be cascaded?
Advantages and specific application scenarios of Ethernet remote IO modules that can be cascaded
For scenarios where data collection control points are linearly distributed, such as streetlights, bridges, streetlights, digital factories, parking lot parking monitoring, smart parking lots, smart parking racks, and building automation control systems in smart parks, using cascading dual Ethernet remote IO modules saves more costs than using single Ethernet remote IO modules.
The Ethernet remote IO module that can be cascaded is a new type of Ethernet remote IO module that supports MAC layer data exchange and can achieve hand in hand connection. This not only saves switch interfaces, but also reduces a large amount of Ethernet cable costs, wiring space, and wiring costs.

2. Using a traditional single Ethernet remote IO module, the data acquisition and control system wiring for a 70 meter high floor requires a 280 meter Ethernet cable.
It can be seen that using cascaded dual Ethernet remote IO modules can save a lot of wiring costs compared to traditional single Ethernet remote IO modules.
Application of Ethernet Remote IO Module in Building Automation System
For building automation systems, each data acquisition control point is linearly distributed in each floor. Therefore, it is very suitable to use Ethernet remote IO modules that can be cascaded to achieve data acquisition and control.
The Ethernet remote IO module that can be cascaded supports MAC layer data exchange and can achieve a hand in hand connection method. This can not only save switch interfaces, but also reduce a large amount of Ethernet cable costs, wiring space, and wiring costs.

What exactly does embedded development do?
Embedded development is a technology similar to programming, but our understanding of the scope of programmers is to do computer software, web development, and also to do apps.
The majority of embedded development is intelligent electronic products, which are designed for hardware programming. This hardware can be understood as a circuit board, usually composed of a controller (processor) chip and different circuits.
The specific program and circuit are generally determined by the product function. For example, an electronic clock product is usually composed of a digital tube and a microcontroller (controller), and then written in C language to download it to the microcontroller to achieve clock display.9001NJ TRICONEX nput/output communication card
Of course, there are far more products that can be developed in embedded systems, including smartphones, wearable devices, drones, robots, mice and keyboards, and so on.
The knowledge system of embedded development and design is also very diverse, and different products require different learning contents.
So, if we want to enter embedded development, we must first understand several directions of embedded development, otherwise you will never find a starting point.
The general mainstream directions are microcontroller development, ARM+Linux development, and FPGA/DSP development.
I have been working on microcontroller development for the past 10 years of my career.
Microcontrollers can be said to be the foundation of all directions. If you have strong microcontroller development capabilities, then ARM+Linux, or FPGA/DSP are easy for you to get started.
The development of microcontrollers is also one of the directions with the lowest threshold for embedded systems. Initially, I was self-taught in electrical engineering and transferred there. It took me about four months from the beginning of my studies to finding a job.
However, at that time, the threshold was still very low, and you could basically find a job by working on a small project with a 51 microcontroller.
If it”s the current situation, you only know these things and have little competitiveness. Nowadays, the main focus of enterprises is on whether you have project experience, rather than what kind of microcontroller you know.
The project experience can be accumulated through practical projects with endless microcontroller programming, which can be said to be the closest to actual development at present.
At present, the salary of single-chip microcontrollers is not low, and it is normal for them to start at 8K in first tier cities, and they can reach 15K after working for 2-3 years.
There are many industries covered by embedded systems, and in the later stage, based on work, we will only focus on one direction. From a macro perspective, we will divide it into embedded software development and embedded hardware development. Software development is mainly based on application software development on systems (Linux, VxWorks, WinCE, etc.), and hardware development includes motherboard design, system porting, cutting, and writing low-level drivers
My personal experience started with microcontrollers. Firstly, I studied C and C++, digital and analog electronics, power electronics, circuit design, microcontroller principles, FreeRTOS, data structures, and computer operating systems. Later, due to work requirements, I relearned university automation control theory, signals and systems, complex functions, linear algebra, calculus, statistics, and compiler principles. These are all basics, and it is important to understand and thoroughly study them, This will bring help to the later research and development work, and there is also a need for more drawing board, drawing board, and practical operation. Without practicing optics, the efficiency is very low, and knowledge is repetitive. Only by repeatedly looking and using can we understand. We can buy some development boards to assist in learning. Now that the internet is developed, network resources can improve our learning efficiency.
Embedded development refers to developing under an embedded operating system, commonly used systems include WinCE, ucos, vxworks, Linux, Android, etc. In addition, develop using C, C++, or assembly; Using advanced processors such as arm7, arm9, arm11, powerpc, mips, mipsel, or operating systems also belongs to embedded development.

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 9001NJ TRICONEX nput/output communication card
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 9001NJ TRICONEX nput/output communication card 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.
Is it better to have a higher number of IO module bit widths?
IO is an important component of PLC, and the collection of PLC information and the output of instructions must be applied to various input and output IO. I don”t know if you have read some IO user manuals. One of their instructions is the device”s bit width, such as 12 bits and 16 bits. So, is it better to have a higher number of bit widths for the IO module? Let”s talk about this matter.
Bit width is the number of bits of data that can be transmitted within a clock cycle, and the larger the number of bits, the greater the amount of data that can be transmitted instantly. From this perspective, the larger the bit width of the IO module, the better. This is not a problem. However, the amount of data transmission, also known as data bandwidth, depends not only on the bit width, but also on the frequency of data transmission. The multiplication of the two is the final total amount of data transmitted. That is to say, even if the light position is wide, but the frequency is too high, it still cannot work. At the same time, the larger the bit width, the higher the hardware cost, and the greater the heat generation and power consumption of the device.
How to Apply Ethernet IO Module to Weighbridge Data Collection9001NJ TRICONEX nput/output communication card
Weighbridge, a large scale set on the ground, usually used to weigh the tonnage of cargo carried by a truck. It is the main weighing equipment used for measuring bulk goods in factories, mines, merchants, etc. The MXXXX series of Ethernet IO modules with barium rhenium technology have rich IO ports that can be used to assist in data collection and transmission of the weighbridge, quickly achieving comprehensive management of data and control.
Before the vehicle enters the weighbridge, there will be an infrared sensor scanning about a few hundred meters. The infrared sensor will output a switch signal to the Ethernet IO module, indicating that a vehicle needs to enter. Before the vehicle officially enters the weighbridge for weighing, there will be an infrared barrier sensor scanning, and the barrier will also output a switch signal to the Ethernet IO module. When the vehicle is completely parked in front of the weighbridge (including whether the position is correct), the central control room will decide whether to start weighing based on the information received by the IO module from the radar sensor. Finally, the vehicle is weighed and drives away from the weighbridge. The scanning signal from the infrared barrier sensor at the exit is transmitted to the IO module, and the central control room controls the IO port of the IO module to open (close) the barrier. The green light will light up, and the vehicle will fully exit and leave the weighing weighbridge. The entire weighing process requires only one Ethernet IO module to collect information and control actions.9001NJ TRICONEX nput/output communication card

What are the types of integrated IO modules9001NJ TRICONEX nput/output communication card
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.

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.9001NJ TRICONEX nput/output communication card
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.
