实现顺序控制的PLC程序设计

Program Design of Programmable Controller (PLC) of Achievement Order Controller

顺序控制在工业控制中被广泛应用。本文介绍应用日本 ＯＭＲＯＮ公司的可编程序控制器（ＰＬＣ）中的锁存指令 ＫＥＥＰ（１１），设计顺序控制系统的状态流程图，据此转化为梯形图的一种简单易行的方法。

The oder controller is widely applied in industry controller. This paper introduces a simple way that Keep Command in programmable controller (PLC) of Japan OMRON Corp is applied, and state flow chart of order controller sys- tem is designed and then translated into ladder diagram
