有极强的自检及保护功能。
①故障检测——软件定期地检测外界环境，如掉电、欠电压、锂电池电压过低及强干扰信号等。以便及时进行处理。
②信息保护与恢复——当偶发性故障条件出现时，不破坏PLC内部的信息。一旦故障条件消失，就可恢复正常，继续原来的程序工作。所以，PLC在检测到故障条件时，立即把现状态存入存储器，软件配合对存储器进行封闭，禁止对存储器的任何操作，以防存储信息被冲掉。
③设置警戒时钟WDT（看门狗）——如果程序每循环执行时间超过了WDT规定的时间，预示了程序进入死循环，立即报警。
④加强对程序的检查和校验——一旦程序有错，立即报警，并停止执行。
⑤对程序及动态数据进行电池后备——停电后，利用后备电池供电，有关状态及信息就不会丢失。
PLC的出厂试验项目中，有一项就是抗干扰试验。它要求能承受幅值为1000V，上升时间1nS，脉冲宽度为1μS的干扰脉冲。一般，平均故障间隔时间可达几十万～上千万小时；制成系统亦可达4～5万小时甚至更长时间。
