一．系统组成。
二．各部分的作用。
1． CPU运算和控制中心
起“心脏”作用。
纵：当从编程器输入的程序存入到用户程序存储器中，然后CPU根据系统所赋予的功能（系统程序存储器的解释编译程序），把用户程序翻译成PLC内部所认可的用户编译程序。
横：输入状态和输入信息从输入接口输进，CPU将之存入工作数据存储器中或输入映象寄存器。然后由CPU把数据和程序有机地结合在一起。把结果存入输出映象寄存器或工作数据存储器中，然后输出到输出接口、控制外部驱动器。
组成：CPU由控制器、运算器和寄存器组成。这些电路集成在一个芯片上。CPU通过地址总线、数据总线与I/O接口电路相连接。
2． 存储器
具有记忆功能的半导体电路。
分为系统程序存储器和用户存储器。
系统程序存储器用以存放系统程序，包括管理程序，监控程序以及对用户程序做编译处理的解释编译程序。由只读存储器、ROM组成。厂家使用的，内容不可更改，断电不消失。
用户存储器：分为用户程序存储区和工作数据存储区。由随机存取存储器（RAM）组成。用户使用的。断电内容消失。常用高效的锂电池作为后备电源，寿命一般为3~5年。
3．输入/输出接口
（1）输入接口：
光电耦合器由两个发光二极度管和光电三极管组成。
发光二级管：在光电耦合器的输入端加上变化的电信号，发光二极管就产生与输入信号变化规律相同的光信号。
光电三级管：在光信号的照射下导通，导通程度与光信号的强弱有关。在光电耦合器的线性工作区内，输出信号与输入信号有线性关系。
输入接口电路工作过程：当开关合上，二极管发光，然后三极管在光的照射下导通，向内部电路输入信号。当开关断开，二极管不发光，三极管不导通。向内部电路输入信号。也就是通过输入接口电路把外部的开关信号转化成PLC内部所能接受的数字信号。
（2）输出接口
PLC的继电器输出接口电路
工作过程：当内部电路输出数字信号1，有电流流过，继电器线圈有电流，然后常开触点闭合，提供负载导通的电流和电压。当内部电路输出数字信号0，则没有电流流过，继电器线圈没有电流，然后常开触点断开，断开负载的电流或电压。也就是通过输出接口电路把内部的数字电路化成一种信号使负载动作或不动作。
三种类型：
继电器输出：有触点、寿命短、频率低、交直流负载
晶体管输出：无触点、寿命长、直流负载
晶闸管输出：无触点、寿命长、交流负载
4．编程器
编程器分为两种，一种是手持编程器，方便。我们实验室使用的就是手持编程器。二种是通过PLC的RS232口。与计算机相连。然后敲击键盘。通过NSTP-GR软件（或WINDOWS下软件）向PLC内部输入程序。
