步进阶梯设计设计依据如图6所示。图7a为按图6所示要求采用移位指令设计法设计的顺序控制系统步进阶梯，这种步进阶梯由一个8位移位寄存器（由移位指令定义辅助继电器M20～M27而成）作为控制元件。该移位寄存器中的IN为移位数据输入端，CP为移位脉冲输入端，R为复位端。这三个输入端的输入信号均为脉冲上升沿有效。对顺序控制系统来说，输入IN的信号必须是一个单脉冲信号，即移位数据为“1”。起动步1时，IN和CP同时输入按钮信号X0的脉冲上升沿后，在IN端生成的移位数据“1”便移入移位寄存器的M20位，此时该位有输出（即输出M20的常开触点闭合信号），建立步1程序，并为步2提供步进条件信号；M20的常闭触点即时断开IN输入端和CP的步1输入端，完成数据“1”输入和移位脉冲输入。从步2起，本步的转步主令信号一发出（X2接通），便输入一个移位脉冲上升沿，使原来移入M20位的数据“1”移入M21位，建立步2程序，并为步3提供步进条件信号。移位后，M20位的状态变为0，即其相应的步1被撤销，输出为0。依此类推便可实现整个步进阶梯逐步得电和逐步失电。最后一步完成并回到原位（X1接通）时，接通移位寄存器的复位端R，使移位寄存器复位清零，整个控制系统失电停止
