描述

第一个X0的上升沿，将使Y0线圈接通并自锁。同时，CT100对X0作减1计数。X0的第二个上升沿到来时对Y0不起作用，但CT100对其计数，故C100常开闭合使R0线圈接通。下一个扫描周期，断开了的R0常闭触点使Y0线圈断开并打开自锁；闭合了的R0常开触点使CT100复位，进而C100常开触点断开使R0线圈断开，整个系统复位等待第三个X0的上升沿……。图中R9013是PLC初始闭合继电器触点，在系统中起初始复位作用。因为CT100默认为保持型，Y0为非保持型，在Y0输出状态下电源断电或PLC由运行转为编辑后Y0断开而CT100保持计数值“1”。若梯形图中去掉R9013常开触点，在系统再恢复运行时第一次按动X0将不能启动系统，只有在第二次按动X0时才能启动系统。
