PLC编程中功能流程图到梯形图的转换剖析

Conversion Analysis Between Function Flowchart and Ladder of PLC Programming

在简要介绍梯形图的基础上,着重分析了PLC编程中功能流程图到梯形图的转换方法,并给出了西门子S7-200系列PLC的应用实例,以便初学者接受和掌握。

In order to make the new learner accept and master the way to convert Function flowchart to Ladder of PLC Programming,an example about series of Siemens S7-200 PLC is given in this paper based on simple introduction of Ladder.
