1. Central processing unit

The central processing unit (CPU) consists of a controller, an operator and registers and is integrated into a chip. The CPU is connected to memory, I/O interface, programmer and power supply through data bus, address bus, control bus and power supply bus.

The CPU of small PLC uses 8 bit or 16 bit microprocessor or single chip microcomputer, such as 8031, M68000 and so on, this kind of chip price is very low; The CPU of medium-sized PLC uses 16 bit or 32 bit microprocessor or microcontroller, such as 8086, 96 series microcontroller, etc., this kind of chip is mainly characterized by high integration, fast computing speed and high reliability; And large PLC needs to use high speed bit chip microprocessor.

The CPU commands the PLC control system to complete various tasks according to the function given by the system program in PLC.

Step 2: Memory

The memory in PLC is mainly used to store system programs, user programs and data.

1) System program memory

PLC system program determines the basic function of PLC, the part of the program written by the PLC manufacturer and solidified in the system program memory, mainly has the system management program, user instruction interpretation program and function program and system program call and other parts.

The system management program mainly controls the operation of PLC, so that PLC works in the correct order; The user instruction interpreter converts the PLC user instruction into machine language instruction and transmits it to the CPU for execution; The function program and system program call are responsible for calling different function subroutines and their management programs.
