      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。
