图1－1－1所示的过程是简化的过程，实际的 PLC工作过程还要复杂些。除了 I/O刷新及运行用户程序，还要做些公共处理工作。 
公共处理工作有：循环时间监控、外设服务及通讯处理等。
监控循环时间的目的是避免"死循环"，避免程序不能反复不断地重复执行。办法是用""（Watching dog）。只要循环**时，它可报警，或作相应处理.
外设服务是让PLC可接受编程器对它的操作，或通过接口向输出设备如打印机输出数据.
通讯处理是实现PLC与PLC，或PLC与计算机，或PLC与其它工业控制装置或智能部件间信息交换的。这也是增强PLC控制能力的需要。
也就是说，实际的PLC工作过程总是：公共处理--I/O刷新--运行用户程序--再公共处理--……反复不停地重复着。
