CPU（Central  Process  Unit）

CPU是PLC的核心组成部分，与通用微机的CPU一样，它在PLC系统中的作用类似于人体的神经中枢，故称为“电脑"。其功能是：

a、按PLC中系统程序赋予的功能，接收并存储从编程器输入的用户程序和数据。

b、用扫描方式接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内部电路的工作状态和编程过程中的语法错误。

d、在PLC进入运行状态后，从存储器中逐条读取用户程序，经过命令解释后按指令规定的任务，产生相应的信号，去启闭有关控制门电路。分时分渠道地去执行数据的存取、传送、组合、比较和变换等操作，完成用户程序中规定的逻辑式算术运算等任务。根据运算结果，更新有关标志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主要采用通用微处理器、单片机或双极型位片式微处理器。通用的微处理器常用的是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。双极型位片式微处理器常用的有AMD2900、AMD2903等。

①用通用微处理器作CPU

在低档PLC中，用Z80A做CPU较为普遍，Z80A用于PLC有如下长处： Z80（或Z80A）CPU及其配套的芯片廉价、普及、通用，用这套芯片制成的PC，给维修及推广普及带来方便。Z80有独立的输入/输出指令,而且指令格式较短，执行时间也较短，这样有利于扫描周期的缩短。Z80输入/输出指令格式较短，相应的输入/输出设备编码也较短，所以相应的译码硬件器较简单。由于Z80的信息是采用输入/输出映射方式，因而设计流程序时，对输入/输出与存储器寻址容易区别。

②用单片机作CPU

自从1974年出现单片机以来，已有不少产品采用单片机做可编程序控制器。日本三菱F系列PLC就采用美国IN公司MES－48系列的单片机8049和8039做处理器，8039单片机在一块片子上集成了8位的CPU，128×8的数据存储器。27条输入/输出线，T0、T1、INT测试线及8位定时器/计数器，时钟振荡电路等。

自80年代以来，出现了集成度更高。功能更强，并带有“布尔机"而又便于作数据通信的MCS-51系列单片机以及功能更高的16位单片机，大有取代MCS－48系列之势。日本三菱的F2系列PLC即采用CPU8031。MCS－51系列单片机是美国IN公司在MCS－48单片机基础上，于80年代初推出的产品，具有高集成度、高可靠性、高功能、高速度、低价格等特点。它有三个代表产品：8051、8751和8031，它们分别有不同的应用特性
