IC693CPU331

 

 

可编程控制器的构成框图和盘算机是一样的，都由中央处置处罚器（CPU）、存贮器和输入/输出接口等构成。因此，从硬件布局来说，可编程控制器现实上便是盘算机，图1是其硬件体系的简化框图。从图中可以看出PLC内部重要部件有:

 

（1）CPU（Central  Process  Unit）

 

CPU是PLC的核心构成部分，与通用微机的CPU一样，它在PLC体系中的作用雷同于人体的神经中枢，故称为“电脑”。其功效是：

 

a、按PLC中体系步伐付与的功效，吸收并存储从编程器输入的用户步伐和数据。

 

b、用扫描方法吸收现场输入装置的状态式数据，并存入映象寄存器或数据寄存器中。

 

c、诊断电源、PLC内部电路的事情状态和编程历程中的语法错误。

 

d、在PLC进入运行状态后，从存储器中逐条读取用户步伐，颠末下令表明后按指令划定的使命，产生相应的信号，去启闭有关控制门电路。分时分渠道地去实行数据的存取、传送、组合、比力和变更等操纵，完成用户步伐中划定的逻辑式算术运算等使命。凭据运算结果，更新有关标记位的状态和输出映象寄存器的内容，再由输出映象寄存器的位状态式数据寄存器的有关内容，实现输出控制、制表、打印式数据通讯等。

 

PLC常用的CPU重要接纳通用微处置处罚器、单片机或双极型位片衰落处置处罚器。通用的微处置处罚器常用的是8位机和16位机，如Z80A、8085、8086、6502、M6800、M6809、M68000等。单片机常用的有8039、8049、8031、8051等。双极型位片衰落处置处罚器常用的有AMD2900、AMD2903等。
