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:3720 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.

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.
Its advantages are as follows:3720 TRICONEX controller

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.
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.
Its advantages are as follows:
1. No need for a large number of Ethernet switches or occupying Ethernet switch ports;
2. It can save a lot of Ethernet cables, cable space, and labor costs for installing cables;
3. The overall cost has significantly decreased;

Ethernet IO module assists industrial robots
Industrial robots are multi joint robotic arms or multi degree of freedom machine devices aimed at the industrial field, which can achieve many material distribution, retrieval, pallets, and so on in industrial sites. However, due to the fact that many industrial six axes are equipped with 32 IO ports as standard, the IO ports are not sufficient in practical applications. Therefore, some DIN and DO extensions can be met through IO modules.
MQTT Ethernet IO Remote Module3720 TRICONEX controller
The Modbus TCP Ethernet IO module has multiple channels, such as 4-way, 8-way, and 16-way switch input and output options. The communication protocol of the Ethernet IO module adopts the standard Modbus TCP protocol, Modbus RTU over TCP protocol, and MQTT protocol. Can support LAN configuration, with 1 DC power output to other devices on site, reducing the difficulty and cost of on-site wiring.
Most of the MQTT Ethernet IO modules should collect some IO port information and transmit data through the network port. In fact, the Ethernet IO module can not only serve as a TCP server, but also as a TCP client. In addition, it can not only count high-speed pulses but also output high-3720 TRICONEX controllerspeed pulses. This is very convenient for doing some control processing on industrial sites, such as controlling servo motors and other scenarios! The most important thing is the data caching function. Even if the network is disconnected, it is not afraid. The data will be automatically cached, and after the network is restored, it will be automatically retransmitted.
The MxxxT industrial remote Ethernet I/O data acquisition module is embedded with a 32-bit high-performance microprocessor MCU, and integrates an industrial grade 10/100M adaptive Ethernet interface to support the standard Modbus protocol. It can easily integrate with third-party SCADA software, PLC, and HMI devices for application. Equipped with an RS485 interface, it has good scalability and can be cascaded with standard Modbus RTU I/O devices through the RS485 bus to achieve the combination of various digital, analog, and thermal resistance IO modules, saving costs. At the same time, this device has the function of cluster register mapping, and the data of the cluster is automatically collected into the mapping storage area of the local computer. The upper computer can respond quickly without waiting when querying, meeting the strict and timely functional requirements of industrial sites.
What is a remote IO module and what are its purposes
Technology is constantly evolving, and we can come into contact with various electronic devices both in daily life and in the workplace. And a large number of electronic devices work together to generate some signal sources. In order to better transmit and collect signals, industrial control products such as remote IO modules, signal transmitters, and signal acquisition modules have been developed.
In the past, people had to connect existing lines and boxes one at a time, which greatly increased the cost and construction time of cables. Moreover, if the distance was too long, they also had to face issues such as voltage attenuation. And through the remote IO module, this problem can be effectively solved.
If your cabinet is 200 meters away from the site and remote IO is not used, then you can extend each signal line by 200 meters and install the remote IO module on site, which can save you a lot of cable costs and reduce the complexity of construction.
In short, sometimes some IOs are set far away from the central control room and then connected back to the central control room through fiber optics to save on cable procurement and construction. Sometimes, the logical “remote” is because the allowed quantity of “local IO” cannot meet the actual needs, so it is necessary to connect to the “remote IO template”, which depends on the situation.
In addition, the general cabinet is placed on the equipment site. However, some control signals, such as emergency stop and bypass, are implemented in the control room, so remote IO modules need to be used to transmit these signals to the control system in the computer room.
What is an Ethernet IO module and what are its functions
The Ethernet IO module is a hardware gateway that adds IO to the network port.
The Ethernet IO module has hardware interfaces such as switches, analog signals, relays, RS485, RJ45, etc. Can be used for IO data collection network port transmission in industrial automation. Simply put, it refers to sensors with standard signals on site, or serial devices with 485 signals such as PLCs, which can be converted into real values through such gateways and then transmitted to the host for display through network ports.
