描述

CPU模块相当于人的大脑和心脏，它不断地采集输入信号，执行用户程序，刷新系统的输出；存储器用来储存程序和数据。

1．CPU芯片

CPU模块主要由CPU芯片和存储器组成。PLC使用以下几类CPU芯片：

(1)通用微处理器，如Intel公司的8086，80186到Pentium系列芯片；

(2)单片微处理器(单片机)，如Intel公司的MCS51／96系列单片机；

(3)位片式微处理器，如AMD2900系列位片式微处理器。

2．存储器

PLC的存储器分为系统程序存储器和用户程序存储器。系统程序相当于个人计算机的操作系统，它使PLC具有基本的智能，能够完成PLC设计者规定的各种工作。系统程序由PLC生产厂家设计并固化在ROM内，用户不能直接读取。PLC的用户程序由用户设计，它决定了PLC的输入信号与输出信号之间的具体关系。用户程序存储器的容量一般以字(每个字由16位二进制数组成)为单位，三菱的FX系列PLC将用户程序存储器的单位称为步(Step，即字)。小型PLC的用户程序存储器容量在lK字左右，大型PLC的用户程序存储器容量可达数M(兆)字。
