一、查找PLC故障步骤
（1）如果该信号控制在一个计数器 ，首先检查控制复位的逻辑，然后是计数器信号。按上述2到5步进行。
(2)如果PLC停止在某些输出被激励的地方，一般是处于中间状态，则查找引起下一步操作发生的信号（输入，定时器，线川，鼓轮控制器等）。编程器回显示那个信号的ON/OFF状态。
（3）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，结果不一致，则更换输入模块。如果发现在扩展架上有多个模块要更换，那么，在更换之前，应先检查I/O扩展电缆和她的连接情况。
（4）如果输入状态与输入模块的LED指示指示一致，就要比较一下发光二极管与输入装置（按钮、限位开关等）的状态。如果二者不同，测量一下输入模块，如发现问题，需要更换I/O装置，现场接线或电源；否则，要更换输入模块。
（5）如果信号是定时器，而且停在小于999.9的非零值上，则要更换CPU模块。
（6）如信号是线川，没有输出或输出与线川的状态不同，就得用编程器检查输出的驱动逻辑，并检查程序清单。检查应按从左到右进行，找出第一个不接通的触点，如没有通的那个是输入，就按第二个和第三步检查该输入点，日是线川，就按第四步和第五步检查。要确认使主控继电器不影响逻辑操作。
二、组件的更换
1.更换框架
（1）切断AC电源；如装有编程器，拔掉编程器。
（2）从框架右端的接线端板上，拔下塑料盖板，拆去电源接线。
（3）拔掉所有I/O模块。如果原先在安装时有多个回路的话，不要搞乱IU/O的接线，并记下每个模块在框架的位置，以便重新插上时不至于搞乱。
（4）如果CPU框架，拔除CPU组建和填充模块。将它放在安全的地方，以便以后安装。
（5）卸去底部的二个固定框架的螺丝，松开上部二个螺丝，但不用拆掉。
（6）将框架向上推移一下，然后把框架向下拉出来放在旁边。
（7）将新的框架从顶部螺丝上套进装上底部螺丝，将四个螺丝都拧紧。
（9）插入I/O模块，注意位置要与拆下时一致如果模块插错位置，将会引起控制系统危险的或错误的操作，但不会损害模块。
（10）插入卸下的CPU模块和填充模块。
（11）在框架右边的接线端上重新接好电源，再盖上电源接线端的塑料盖。
（12）检查一下电源接线是否正确，然后再通上电源。仔细地检查整个控制系统的工作，确保所有的I/O模块位置正确，程序没有变化。
2. CPU模块的更换
（1） 切断电源，如装有编程器，拔掉编程器。
（2）向中间挤压CPU模块面板上的上下紧固扣使它们脱出卡口。
（3）把模块从槽中垂直拔出。
（4）如果CPU上装着EPROM储存器，把EPROM拔下，装在新的CPU上。
（5）首先将印刷线路板对准底部导槽。将新的CPU模块插入底部导槽。
（6）轻微的晃动CPU模块，使CPU模块对准顶部导槽。
（7）把CPU模块插进框架，直到二个弹性锁扣扣进卡口。
（8）重新插上编程器，并通电。
（9）在对系统编程初始化后，把录在磁带上的程序重新装入。检查一下整个系统的操作。
3.I/O模块的更换
（1）切断框架和I/O系统的电源。
（2）卸下I/O模块接线端上的塑料盖。拆下有故障模块的现场接线。
（3）拆去I/O接线端的现场接线或卸下可拆式接线插座，这要视模块的类型而定。给每根线贴上标签或记下安装连线的标记，以便于将来重新连接。
（4）向中间挤压I/O模块的上下弹性锁扣，使它们脱出卡口。
