针对目前采用小型可编程序逻辑控制器（PLC ）实现顺序控制所存在的问题，采用模块化转换思想，使用5种不同方法将顺序功能图转换为梯形图。提高了顺控编程方法的规律性，实现其编程方法的简单、实用。以西门子S7-200 PLC为例进行实例转换分析，最后对各转换方法进行了综合比较。

According to the present weakness of the sequence control using small programmable logic con-troller (PLC) ,the modular transformation thought was adopted and five different methods to transfer sequential function chart (SFC) into ladder diagram (LAD) were used .It makes the programming meth-od simple and practical .Finally ,a transformation example based on SIEMENS S7-200 PLC was analyzed , and the comprehensive comparison of the conversion method was made .
