外部的开关信号、模拟信号以及各种传感器检测信号作为PLC的输入变量，它们经PLC的输入端子进入PLC的输入存储器，收集和暂存被控对象实际运行的状态信息和数据；经PLC内部运算与处理后，按被控对象实际动作要求产生输出结果；输出结果送到输出端子作为输出变量，驱动执行机构。PLC的各部分协调*地实现对现场设备的控制。
    （1）*处理器CPU
    CPU的主要作用是解释并执行用户及系统程序，通过运行用户及系统程序完成所有控制、处理、通信以及所赋予的其它功能，控制整个系统协调*地工作。常用的CPU主要有通用微处理器、单片机和双极型位片机。
    （2）存储器模块

   随机存取存储器RAM用于存储PLC内部的输入、输出信息，并存储内部继电器（软继电器）、移位寄存器、数据寄存器、定时器／计数器以及累加器等的工作状态，还可存储用户正在调试和修改的程序以及各种暂存的数据、中间变量等。
    只读存储器ROM用于存储系统程序。可擦除可编程序的只读存储器EPROM主要用来存放PLC的操作系统和监控程序，如果用户程序已*调试好，也可将程序固化在EPROM中。
    （3）输入输出模块
    可编程序控制器是一种工业控制计算机系统，它的控制对象是工业生产过程，与DCS相似，它与工业生产过程的也是通过输入输出接口模块（I/O）实现的。I/O模块是可编程序控制器与生产过程相的桥梁。
