欧姆龙-MCS-51与PLC通讯

资料介绍：
在工控现场单片机与可编程序控制器(PLC)的应用日益广泛。单片机将各种功能部件集中在一块芯片中因此结构紧凑、体积小、可靠性高、抗干扰能力强、价格低廉易于开发使用应用范围广。PLC则使用简单方便、故障率低、对现场要求不高其模块化的结构又易于在实际中对不同对象进行组合、扩展满足工业控制的需要。因而在自控系统中人们通常将两者配合使用这样就需要用到单片机和PLC的通讯了。MCS-51系列为Intel公司的产品其代表产品为8051但工控现场常用的是8031。8031内部没有程序存贮器但实用中只要用到地址锁存器和EPROM配以简单的外电路即可实现小系统。我国小型PLC主要是日本的产品其中OMRON公司占首位。所以下面的讨论中我将以8031单片机与OMRONPLCCPM1A为例讲述它们之间的串行通讯。2系统结构与功能2.1器的配置在单片机实际系统的开发中我们通常是先根据工控要求、编制出程序然后在器上运行调试通过单步、设置断点和连续运行等方法调试通过后再把程序固化到EPROM把这EPROM插入到用户样机中这样用户系统就制作好了。
