CPU is the core of PLC, playing a central role in the nervous system. Each set of PLC has at least one CPU, which receives and stores user programs and data according to the functions assigned by the PLC system program. It collects the status or data sent by the on-site input device through scanning and stores it in the specified registers. At the same time, it diagnoses the working status of the power supply and PLC internal circuits, as well as syntax errors in the programming process. After entering operation, read instructions one by one from the user program memory, analyze them, and then generate corresponding control signals according to the tasks specified in the instructions to command the relevant control circuits.

The CPU is mainly composed of arithmetic units, controllers, registers, and the data, control, and status buses that connect them. The CPU unit also includes peripheral chips, bus interfaces, and related circuits. Memory is mainly used to store programs and data, and is an indispensable component of PLC.

In the user’s opinion, it is not necessary to analyze the internal circuits of the CPU in detail, but there should still be sufficient understanding of the working mechanisms of each part. The controller of the CPU controls its operation, allowing it to read, interpret, and execute instructions. But the work rhythm is controlled by oscillation signals. An arithmetic unit is used for performing numerical or logical operations and operates under the command of a controller. Registers participate in operations and store intermediate results, which also operate under the command of the controller.

CPU speed and memory capacity are important parameters of PLC, which determine the working speed, IO quantity, and software capacity of PLC, thus limiting the control scale.
