PLC编程中SFC图转换到梯形图的方法探讨

Discussion on the Method of Converting SFC Diagram to Ladder Diagram in PLC Programming

顺序功能图(SFC)编程语言是设计PLC顺序控制程序的一种有力工具,能够较容易地编写出复杂的顺序控制程序,从而提高工作效率,对程序调试也极为方便。以彩灯循环点亮过程为例,着重分析PLC编程中SFC图转换到梯形图的方法。

Sequential function chart(SFC) programming language is a powerful tool for design of PLC Sequential control program, can be easier to write complex sequential control program, so as to improve the work efficiency, for program debugging is also very convenient. Taking the process of the lantern cycle as an example, the method of converting the SFC diagram to the ladder diagram in the PLC programming is analyzed emphatically.
