PLC的工作方式为扫描加中断，这既可***它能有序地工作，避免继电控制系统常出现的"冒险竞争"，其控制结果总是确定的；而且又能应急处理急于处理的控制，***了PLC对应急情况的及时响应，使PLC能可靠地工作。
为监控PLC运行程序是否正常，PLC系统都设置了"看门狗"（Watchingdog）监控程序。运行用户程序开始时，先清"看门狗"定时器，并开始计时。当用户程序一个循环运行完了，则查看定时器的计时值。若超时（一般不超过100ms），则报警。严重超时，还可使PLC停止工作。用户可依报警信号采取相应的应急措施。定时器的计时值若不超时，则重复起始的过程，PLC将正常工作。显然，有了这个"看门狗"监控程序，可***PLC用户程序的正常运行，可避免出现"死循环"而影响其工作的可靠性。
