三菱fx2系列的步进指令

1、本章介绍专门用于步进顺控过程的步进顺控指令及其编程方法状态转移图法。要求掌握用SFC语言来描www.PLC述复杂的步进顺控过程的设计思路，掌握单流程结构、选择与并行分支结构以及循环结构的状态编程； 要求能用结构化程序设计的特点来分析与设计用SFC语言编制的分支与汇合的组合状态流程；要求能熟练的使用FXGP 编程软件， 设计步进梯形图、指令表和SFC，并能灵活地将SFC转换成步进梯形图。2011/4/221FX2N PLC4.1 SFCSFC 3.313.4114.1awww.PLC2011/4/222图4.1 动力头1的状态编程4.1.1SFC24.1a3.4SFC FX2N
