PLC控制着一个复杂系统，所能看到的是上下两排错开的输入输出继电器接线端子、对应的指示灯及PLC编号，就像一块有数十只脚的集成电路。任何一个人如果不看原理图来检修故障设备，会束手无策，查找故障的速度会特别慢。

通过程序逻辑推断故障

现在工业上经常使用的PLC种类繁多，对于低端的PLC而言，梯形图指令大同小异，对于中机，如S7-300，许多程序是用语言表编的。实用的梯形图有中文符号注解，否则阅读很困难，看梯形图前如能大概了解设备工艺或操作过程，看起来比较容易。

若进行电气故障分析，一般是应用反查法或称反推法，即根据输入输出对应表，从故障点找到对应PLC的输出继电器，开始反查满足其动作的逻辑关系。经验表明，查到一处问题，故障基本可以排除，因为设备同时发生两起及两起以上的故障点是不多的。

分合理利用软、硬件资源

不参与控制循环或在循环前已经投入的指令可不接入PLC；

多重指令控制一个任务时，可先在PLC外部将它们并联后再接入一个输入点；尽量利用PLC内部功能软元件，充分调用中间状态，使程序具有完整连贯性，易于开发。同时也减少硬件投入，降低了成本；

条件允许的情况下好独立每一路输出，便于控制和检查，也保护其它输出回路；当一个输出点出现故障时只会导致相应输出回路失控；输出若为正/反向控制的负载，不仅要从PLC内部程序上联锁，并且要在PLC外部采取措施，防止负载在两方向动作；PLC紧急停止应使用外部开关切断，以确保。
