摘要
以FX-2N型PLC为例,阐述送料小车往返控制的设计,顺序控制设计法的思路、顺序功能表图的组成、绘制和停止信号的添加,探讨顺序功能图转换为梯形图的不同方法和特点。
Taking FX-2N PLC as an example, this paper expounds the design of the round-trip control of the feeding trolley, the idea of the sequential control design method, the composition and drawing of the sequential function table diagram and the addition of the stop signal, and discusses the different methods and characteristics of converting the sequential function diagram into a ladder diagram.
