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。
