The hardware of the PLC controller itself adopts the building block structure, and the product structure of each manufacturer is similar. Taking the Japanese Omron C200HE as an example, it is a bus template frame structure. The basic frame (CPU motherboard) is equipped with CPU templates, and other slots are equipped with I/O templates; If there are many I/O templates, the CPU board can connect the I/O expansion board through the I/O expansion cable, and install the I/O template on it; The other method is to equip remote I/O slave station, etc. These all show that PLC manufacturers develop hardware components to users for easy selection, and configure them into PLCs of different sizes. Moreover, the openness of this hardware configuration brings a lot of convenience to manufacturers, distributors (agents), system integrators, and end users, and brings great convenience to the marketing supply chain. This is a great success experience.

In addition to general DI/DO and AD/DA templates, I/O templates in PLC have also developed a series of I/O templates with special functions, which opens the way for PLC to be used in various industries, such as ASCII/BASIC templates for barcode recognition, PID templates for feedback control, high-speed counting templates for operation control and mechanical processing, single-axis position control templates, dual-axis position control templates, cam positioner templates, RFID interface templates, etc, This will have a great development in the future. In addition, the relevant components of input and output, input and output electrical isolation and ground isolation in strong interference situations will also be improved.

The CPU in the PLC cooperates with the memory to complete the control function. It is different from the DCS system that processes temperature, pressure, flow and other parameters. It adopts a fast scanning cycle, which is generally 0.1~0.2s, and the faster scanning cycle is 50ms or less. It is a digital sampling control system.
