可编程控制器应用程序设计的状态识别编码

The Coding for State's Identification of Designing Application's Program of Programmable Controller

介绍可编程控制器（ＰＬＣ） 应用程序设计的状态识别编码和两种编码方法，及用状态表法设计应用程序时两种方法均可使用，并讨论了编码原理及实现方法。

This paper discusses state's identification for designing application's program of programmable controller and two coding methods. This two methods can both be applied to different PLCs programming with the method of state table.The principle and coding method are also introduced.
