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:3501E Safety Instrumented System (SIS)
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.

What is the role of distributed IO modules and what are their main applications in
The distributed IO module transmits status signals from the measurement and control field to various measurement and control fields for control. It is mainly used in the industrial field and can also be used for detection of equipment such as air conditioners and motors.
In distributed systems, there are important business data closely related to system operation, as well as data related to nodes, application services, and data services, which are crucial for the normal operation of clusters.
IO on general PLCs is usually closely followed by CPU units, but in order to facilitate connection and maintenance, the concept of distributed IO has been proposed in the industrial field. That is to say, the IO unit can be arranged far away from the PLC CPU unit and communicate through the network communication protocol of the device layer.
The distributed IO module is developed for detecting and implementing remote control of various types of standard analog and switch signals (frequency, pulse, or switch state signals) in the field of measurement and control. The series of modules can digitize the test signal front-end and transmit it to the host through optical fiber; Or transmit the control instructions sent by the host to the controlled device to achieve remote control. Especially suitable for state detection and control of complex electromagnetic environments in power, industrial control, on-site switchgear, and large power equipment.

Fault tolerance in the TRICONEX 3805E is achieved through the the third mock examination redundancy (TMR) architecture. Tricon can provide error free and uninterrupted control in the event of hard faults or internal or external transient faults in components. Tricon adopts a completely triple architecture design, from the input module to the main processor and then to the output module. Each I/O module contains three independent branch circuits. Each pin on the input module reads process data and passes this information to their respective main processors. The three main processors communicate with each other using a proprietary high-speed bus system called TriBus. Every scan, the three main processors synchronize and communicate with their two neighbors through TriBus. Tricon votes on digital input data, compares output data, and sends copies of analog input data to each main processor. The main processor executes user written applications and sends the output generated by the application to the output module. In addition to voting on input data, TriBus also votes on output data. This is done on the output module as close to the field as possible to detect and compensate for any errors between the Tricon voting and the final output driven to the field.
The TRICONEX 3805E system typically consists of the following typical modules: [2]

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.
