What IO combinations can a mini PLC combine with to achieve automated control?
At present, there are two main design modes for controllers like PLC, one is integrated design and the other is modular design. From the name, we can feel that there are two different PLCs, one that cannot be disassembled and the other that can be disassembled. Due to the fact that the main control module and IO module of the modular PLC can be spliced as needed, its volume and weight are usually very small, and we cannot call it a mini PLC too much. So, what IO combinations can such a small gadget combine with to achieve automation control? Let”s take a brief inventory:4352AN TRICONEX controller
1. Firstly, there is the digital quantity acquisition IO module, which is used to collect digital quantity information. Typical examples include counter IO, PNP type digital quantity acquisition IO, NPN type digital quantity acquisition IO, etc.
2. Then there is the digital output IO module, which is used to send digital instructions. The most typical example is PWM output IO, which can output pulse signals to control servo motors or stepper motors for operation.
3. After talking about digital IO, let”s talk about analog IO. Analog signal acquisition type IO includes voltage signal acquisition, current signal acquisition, and temperature signal acquisition. The IO for collecting temperature signals includes PT100, PT1000, and various thermocouple temperature acquisition modules.
4. Finally, there are analog output IO, as well as output current signals and voltage signals.
In addition to the above IO modules, our modular PLC also supports extended communication interfaces, further enhancing the equipment”s scalability.

Module Input/Output (I/O) Knowledge
I think it”s necessary to talk about the sorting of the input and output ports of the module. Generally, we can divide it into IO functional division and IO specifications.
The purpose of the former is mainly to convert all functions into actual division into MCU IO ports, while the purpose of the latter is to determine the specifications of all IO ports. Of course, you can completely skip these tasks, and it”s also possible. Depending on the company”s requirements, I think individuals still consider them as a work habit.
The following examples are all created for my blog post. If there are any duplicate names, please do not contact me.
Looking at the above figure, first determine all input and output functions and power input, as well as communication.
Then separate the power distribution with different lines, and start organizing each power supply line and processing process. The final purpose of the entire diagram is to clearly allocate the input and output sequence.
The IO specification is to provide a detailed description of all interfaces, crystal oscillators, and other information to the MCU.
1. Enter the number of low effective interfaces and how much pull-up resistance (switch wet current) is required (how much current does the microcontroller need to absorb, which may be injected into the microcontroller after pull-up).
2. Enter the number of highly effective interfaces, how many pull-down resistors are required (switch wet current), (how much current does the microcontroller need to absorb, and it is possible to inject the microcontroller after the switch is effective)
3. Number of analog input interfaces, evaluate whether the analog ports of the microcontroller are sufficient, and confirm the required analog conversion accuracy. Evaluate whether the A/D conversion reference voltage needs to be replaced (to meet accuracy requirements). Consider how many power supplies need to be tested and how many analog input ports are configured.
4. Evaluate the requirements for crystal oscillator accuracy and whether a phase-locked loop is required.
The above requirements are mainly aimed at module design and need to be confirmed during the early development of the module. All requirements can be organized using an Excel table and displayed in the diagram.

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:4352AN 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.
