各种PLC的组成结构基本相同，主要有CPU,电源，储存器和输入输出接口电路等组成。
plc处理器
plc处理器单元一般由控制器、运算器和寄存器组成。CPU通过地址总线、数据总线、控制总线与储存单元、输入输出接口、通信接口、扩展接口相连。CPU是PLC的核心，它不断采集输入信号，执行用户程序，刷新系统输出。
储存器
PLC的存储器包括系统存储器和用户存储器两种。系统存储器用于存放PLC的系统程序，用户存储器用于存放PLC的用户程序。现在的PLC一般均采用可电擦除的E2PROM存储器来作为系统存储器和用户存储器。
输入输出接口单元
PLC的输入接口电路的作用是将按钮、行程开关或传感器等产生的信号输入CPU；PLC的输出接口电路的作用是将CPU向外输出的信号转换成可以驱动外部执行元件的信号，以便控制接触器线圈等电器的通、断电。PLC的输入输出接口电路一般采用光耦合隔离技术，可以有效地保护内部电路。
