步进梯形指令是专门为顺序控制设计提供的指令,它的步只能用状态寄存器S来表示,状态寄存器有断电保持功能,在编制顺序控制程序时应与步进指令一起使用,而且状态寄存器必须用置位指令SET置位,这样才具有控制功能,状态寄存器S才能提供STL触点,否则状态寄存器S与一般的中间继电器M相同。在步进梯形图中不同的步进段允许有双重输出,即允许有重号的负载输出,在步进触点结束时要用RET指令使后面的程序返回原母线。把图1中的0-3用状态寄存器S600-S603代替,代替以后使用步进梯形指令编程,对应的梯形图如图3所示。这种编程方法很容易被初学者接受和掌握,对于有经验的工程师,也会提高设计效率,程序的调试、修改和阅读也很容易,使用方便,程序也较短,在顺序控制设计中应优先考虑,该法在工业自动化控制中应用较多。
