The central processing unit (CPU) of PLC is generally composed of controller, arithmetic unit and register. These circuits are integrated in a chip. The CPU is connected with the storage unit and input/output interface circuit through data bus, address bus and control bus.
Like ordinary computers, CPU is the control center of the whole PLC. It commands the PLC to work in an orderly manner according to the functions given by the system program in the PLC. The CPU mainly completes the following tasks:
Receive and store programs and data input by users through input devices such as programmers.
The status or data of the field signal is received through the I/O unit by scanning and stored in the input image register or data memory.
Diagnose the working fault of PLC internal circuit and syntax error in programming.
After the PLC enters the running state, it executes the user program to complete the processing, transmission and storage of various data and corresponding internal control signals, so as to complete various operations specified by the user instructions.
Respond to requests from various peripheral devices (such as programmers, printers, etc.).
The random type of CPU used by PLC is different. At present, the small PLC is a single CPU system, and the medium and large PLC is a dual CPU or even multiple CPU system. At present, there are three types of microprocessors commonly used in PLC: general purpose microprocessors, single chip microprocessors (that is, single chip microprocessors), and bit chip microprocessors.
