查找一般PLC故障的步骤是怎样的？
PLC维修时，插好编程器，并将开关拨到RUN位置，再根据下列步骤查找：
1）如果PLC停止在某些输出被激励的位置、状态（地方），一般是处于中间状态，则查找引起下一步操作发生的信号，编程器会显示信号的ON/OFF状态。
2）如果输入信号，将编程器显示的状态与输入模块的LED指示作比较，若结果不一致，则说明需要更换输入模块。更换模块前，需要先检查I/O扩展电缆和相关连接是否正常。
3）如果输入状态与输入模块的LED指示一致，则比较发光二极管与输入装置的状态。如果两者不同，则需要测量一下输入模块。如果发现存在问题，则需要更换I/O装置、现场接线、电源等。否则，需要更换输入模块。
4）如果信号是线圈，没有输出或输出与线圈的状态不同，则需要用编程器检查输出的驱动逻辑，并检查程序清单。
5）如果信号是定时器，并停在小于999.9的非零值上，则需要更换CPU模块。
6）如果该信号控制一个计数器，则需要先检查控制复位的逻辑，再检查计数器信号。然后检查、判断相关组件是否异常，需要更换。
