详情描述：

  可编程控制器PLC运行时可能会出现死机的情况，这给工业生产造成不可预估的损失，因此，首先要了解PLC死机的原因，针对原因进行排查，软件或硬件错误都有可能导致PLC死机，下面分别进行介绍：
 
    1、硬件方面 
    （1）I／O窜电，PLC自动侦测到I／O错误，进入STOP模式。 
    （2）I／O损坏，程序运行到需要该I／O的反馈信号，不能向下执行指令。 
    （3）扩展模块(功能型，如A／D)线路干扰或开路等。 
    （4）电源部分有干扰或故障。 
    （5）PLC的连接模块及地址分配模块出故障。 
    （6）电缆引起的故障。 
    2、软件方面 
    （1）触发了死循环。 
    （2）程序改写了系统参数区的内容，却没有初始化部分。 
    （3）保护程序启动：硬件保护、限制使用时间(针对货款收回) 
    （4）数据溢出，步长过大、看门狗 (可修改DOG时间)动作。
