从开关量控制发展到顺序控制、运送处理，是从下往上的连续PID控制等多功能，PID在中断站中。

　　可用一台PC机为主站，多台同型PLC为从站。

　　也可一台PLC为主站，多台同型PLC为从站，构成PLC网络。这比用PC机作主站方便之处是：有用户编程时，不必知道通信协议，只要按说明书格式写就行。

　　PLC网格既可作为独立DCS，也可作为DCS的子系统。

　　PLC主要用于工业过程中的顺序控制，新型PLC也兼有闭环控制功能。

　　DCS：

　　分散控制系统DCS集4C（Communication，Computer， Control、CRT）技术于一身的监控技术。

　　从上到下的树状拓扑大系统，其中通信（Communication）是关键。

　　PID在中断站中，中断站联接计算机与现场仪器仪表与控制装置是树状拓扑和并行连续的链路结构，也有大量电缆从中继站并行到现场仪器仪表。

　　模拟信号，A/D—D/A、带微处理器的混合。

　　一台仪表一对线接到I/O，由控制站挂到局域网LAN。

　　DCS是控制（工程师站）、操作（操作员站）、现场仪表（现场测控站）的3级结构。用于大规模的连续过程控制，如石化等。
