How to Build High Channel Density Digital IO Modules for the Next Generation Industrial Automation Controllers
With the rapid development of industrial automation, digital IO modules have become an indispensable part of industrial automation controllers. The digital IO module can connect the controller with external devices, such as sensors, actuators, etc., to achieve monitoring and control of industrial production processes. However, with the continuous development of industrial automation, digital IO modules need to have higher channel density and stronger functionality to meet the needs of new industrial automation controllers. Therefore, it is very important to build high channel density digital IO modules for the next generation of industrial automation controllers.
The digital IO module is one of the most fundamental modules in industrial automation controllers, and its main function is to connect the controller with external devices to achieve signal input and output. The digital IO module usually includes two parts: a digital input module and a digital output module. The digital input module can convert the digital signals of external devices into signals that the controller can read, while the digital output module can convert the digital signals output by the controller into signals that external devices can read. The channel density of a digital IO module refers to the number of digital input or digital output channels provided on the module, which is the input and output capacity of the module.
With the development of industrial automation, digital IO modules need to have higher channel density and stronger functions to meet the needs of new industrial automation controllers. The following are several aspects to consider when building a high channel density digital IO module for the next generation of industrial automation controllers:3481 TRICONEX controller
1. Choose the appropriate communication protocol
Digital IO modules typically communicate with controllers through communication protocols, so choosing a suitable communication protocol is crucial. Common communication protocols include Modbus, Profibus, CANopen, Ethernet, etc. Different communication protocols have different advantages and disadvantages, and selecting a suitable communication protocol requires considering the following factors:
(1) Communication speed: The faster the communication speed, the shorter the response time of the digital IO module, which can process input and output signals faster.
(2) Communication distance: The farther the communication distance, the wider the application range of digital IO modules.
(3) Reliability: The reliability of communication protocols determines the stability and reliability of digital IO modules.
(4) Cost: Different communication protocols have different costs, and suitable communication protocols need to be selected based on actual needs.
2. Choose the appropriate digital IO chip
The digital IO chip is the core component of the digital IO module, and its performance and function directly affect the channel density and function of the digital IO module. Choosing a suitable digital IO chip requires considering the following factors:
(1) Channel density: The channel density of digital IO chips determines the channel density of digital IO modules, and channel density needs to be selected based on actual needs.
(2) Input/output type: Digital IO chips usually support digital input and digital output, and some chips also support functions such as analog input and output, counters, etc.
(3) Speed: The speed of the digital IO chip determines the response speed of the digital IO module, and it is necessary to choose a chip with a faster speed.
(4) Accuracy: The accuracy of digital IO chips determines the signal accuracy of digital IO modules, and it is necessary to choose chips with higher accuracy.
(5) Cost: Different digital IO chips have different costs, and suitable chips need to be selected based on actual needs.
3. Optimize circuit design
The circuit design of digital IO modules has a significant impact on their performance and stability. In order to improve the channel density and functionality of digital IO modules, it is necessary to optimize circuit design, such as:
(1) Using high-speed digital IO chips: Using high-speed digital IO chips can improve the response speed and accuracy of the module.
(2) Adopting anti-interference design: In order to improve the stability of the digital IO module, it is necessary to adopt anti-interference design, such as using filters, isolators, etc.
(3) Using optimized PCB layout: Optimizing PCB layout can reduce noise and interference in digital IO modules, improve module performance and stability.
4. Choose the appropriate shell material and size
Digital IO modules typically need to be installed in cabinets or control cabinets, so choosing the appropriate housing material and size is crucial. The shell material should have good protective and heat dissipation properties to protect the circuits of the digital IO module from external environmental influences. The shell size should be able to adapt to different installation environments, such as cabinets, control cabinets, etc.
5. Optimize software design
The software design of the digital IO module determines its functionality and performance. In order to achieve high channel density and stronger functionality, it is necessary to optimize software design, such as:
(1) Supporting multiple input and output types: Supporting multiple input and output types can meet different application needs, such as digital input and output, analog input and output, counters, etc.
(2) Supporting multiple communication protocols: Supporting multiple communication protocols can adapt to different controllers and application environments.
(3) Support for online debugging and monitoring: Supporting online debugging and monitoring can facilitate user diagnosis and maintenance of modules.
(4) Support for expansion function: Supporting expansion function can increase the functionality and application range of the module while ensuring channel density.
In summary, building a high channel density digital IO module for the next generation of industrial automation controllers requires multiple considerations, including selecting suitable communication protocols, selecting suitable digital IO chips, optimizing circuit design, selecting suitable shell materials and sizes, and optimizing software design. Only by comprehensively considering these factors can a digital IO module with high channel density and stronger functionality be constructed to meet the needs of new industrial automation controllers.
How to assign IO devices to IO controllers?
PROFINET IO system
The PROFINET IO system consists of a PROFINET IO controller and its assigned PROFINET IO devices. After adding IO controllers and IO devices, it is necessary to assign IO controllers to the IO devices to form a basic PROFINET IO system.
Prerequisite requirements
● Already in the network view of STEP 7.
A CPU has been placed (e.g. CPU 1516-3 PN/DP).
● An IO device has been placed (e.g. IM 155-6 PN ST)
Operating Steps (Method 1)
To assign IO devices to IO controllers, follow these steps:
1. Move the mouse pointer over the interface of the IO device.
2. Hold down the left mouse button.
3. Drag the mouse pointer.
The pointer will now use the networking symbol to indicate the “networking” mode. At the same time, you can see a lock character appearing on the pointer
Number. The lock symbol only disappears when the pointer moves to a valid target position.
4. Now, move the pointer to the interface of the desired IO controller and release the left mouse button.
5. Now assign the IO device to the IO controller.
Operating Steps (Method 2)
To assign IO devices to IO controllers, follow these steps:
1. Move the mouse pointer over the word “Unassigned” in the bottom left corner of the IO device icon.
2. Click the left mouse button.
3. Select the IO controller interface to be connected from the available interfaces that appear.
4. Now assign the IO device to the IO controller.
What are the types of integrated IO modules3481 TRICONEX controller
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.3481 TRICONEX controller
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.
