IC693PIF301 PLC的基本结构和工作原理

作为一种工业控制的计算机，PLC和普通计算机有着相似的结构；但是由于使用场合、目的不同，在结构上又有一些差别。

1.PLC的硬件组成

PLC硬件系统的基本结构如下

PLC的主机由CPU、存储器（EPROM、RAM）、输入/输出单元、外设I/O接口、通信接口及电源组成。对于整体式PLC，这些部件都在同一个机壳内。而对于模块式PLC，各部件独立封装，称为模块，各模块通过机架和电缆连接在一起。主机内的各个部分均通过电源总线、控制总线、地址总线和数据总线连接，根据实际控制对象的需要配备外部设备，构成不同的PLC控制系统。常用的外部设备有编程器、打印机、EPROM写入器等。PLC可以配置通信模块与上位机及其他的PLC进行通信，构成PLC的分布式控制系统。
