CPU is the core part of PLC. Like the general microcomputer CPU, the role of CPU in the PC system is similar to the nerve center of the human body. Its function:

Receive the status or data of the field input device by scanning (described later) and store it in the input image register or data register;

Receive and store user programs and data input from the programmer;

Diagnose the working state of the power supply and the internal circuit of the PC and the syntax errors in the programming process;

After the PC enters the running state:

Execute user program – generate corresponding control signals (read the instructions one by one from the user program memory, and after the instructions are explained, generate corresponding control signals according to the tasks specified by the instructions to open and close the relevant control circuits)

Perform data processing – perform data access, transmission, combination, comparison, transformation and other actions in different time and channels to complete the logical or arithmetic operation tasks specified in the user program

Update output status – output implementation control (update the status of relevant flag bits and the content of output image register according to the operation result, and then realize output control, tabulation, printing, data communication, etc. by the content of input image register or data register)
