与通用计算机一样，主要由运算器、控制器、寄存器及实现它们之间联系的数据、控制及状态总线构成，还有外围芯片、总线接口及有关电路。它确定了进行控制的规模、工作速度、内存容量等。内存主要用于存储程序及数据，是PLC不可缺少的组成单元。

CPU的控制器控制CPU工作，由它读取指令、解释指令及执行指令。但工作节奏由震荡信号控制。

CPU的运算器用于进行数字或逻辑运算，在控制器指挥下工作。

Like a general purpose computer, it is mainly composed of an arithmetic device, a controller, a register and the data, control and state bus that realize the connection between them, as well as peripheral chips, bus interfaces and related circuits. It determines the scale of the control, the speed of operation, the amount of memory, and so on. Memory is mainly used to store programs and data, and is an indispensable component of PLC.

The controller of the CPU controls the work of the CPU, by which the instructions are read, interpreted and executed. But the pace of work is controlled by oscillating signals.

The processor of the CPU is used to perform digital or logical operations, working under the command of the controller.
