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:3806E 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.

The difference between Ethernet remote IO module and industrial computer IO board card
The application of Ethernet remote IO module is very extensive, mainly used for distributed data collection and control, especially suitable for situations where data points are scattered and control points are scattered.
The traditional approach is to connect various instrument signals directly to the IO card through cables using an industrial computer and an IO board card. This method has high wiring costs and high signal attenuation.
The Ethernet remote IO module can directly connect the IO module to the PLC or industrial control computer, and connect the IO to the PLC or industrial control computer through an Ethernet cable. Various instrument controller signals can be directly connected to the Ethernet IO module nearby, which has several advantages:
1. It saves industrial control computers and IO boards, and Ethernet IO modules can be directly connected to the upper computer system;
2. Replacing 4-20mA signal transmission with 10/100MHz Ethernet transmission has improved transmission speed;
3. Replacing various instrument controller signal lines with an Ethernet cable reduces the attenuation of remote signal transmission;
4. The signal cable of the instrument controller only needs to be connected to the Ethernet IO module, greatly reducing cable costs and wiring workload;
5. The M160T series Ethernet remote IO module can also be directly transmitted to the Internet of Things platform through MQTT for remote monitoring.

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.

6. Can be connected to SCADA systems, PLC systems, or cloud platforms;
7. The series uses a MAC layer for data exchange, ensuring that network connectivity does not cause communication issues with subsequent devices due to device failures in the middle.
The comparison between cascaded Ethernet remote IO modules and traditional IO modules used in building automation systems is shown in the following figure:
1. Adopting a cascaded dual Ethernet remote IO module, data acquisition and control wiring for floors with a height of 70 meters only requires a 70 meter Ethernet cable;
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.
