   ①Q、M、S、C等元器件的位保持跳转前的状态； 

      ②计数器C停止计数，当前值存储器保持跳转前的计数值； 

      ③对定时器来说，因刷新方式不同而工作状态不同。在跳转期间，分辩率为1 ms和10 ms的定时器会一直保持跳转前的工作状态，原来工作的继续工作，到设定值后其位的状态也会改变，输出触点动作，其当前值存储器一直累计到zui大值32 767才停止。对分辨率为100 ms的定时器来说，跳转期间停止工作，但不会复位，存储器里的值为跳转时的值，跳转结束后，若输入条件允许，可继续计时，但已失去了准确计时的意义。所以在跳转段里的定时器要慎用。跳转指令的使用方法如图2所示。
