PLC控制系统主要由输入部分、CPU、采样部分、输出控制和通讯部分组成，如图1所示。输入部分包括控制面板和输入模板；采样部分包括采样控制模板、AD转换模板和传感器；CPU作为系统的核心，完成接收数据，处理数据，输出控制信号；输出部分有的系统用到DA模板，将输出信号转换为模拟量信号，经过功放驱动执行器；大多数系统直接将输出信号给输出模板，由输出模板驱动执行器工作；通讯部分由通讯模板和上位机组成。因为PLC本身的故障可能性极小，系统的故障主要来自外围的元部件，所以它的故障可分为如下几种：
传感器故障；
执行器故障；
PLC软件故障
这些故障，都可以用合适的故障诊断方法进行分析和用软件进行实时监测，对故障进行预报和处理。
