目前，在连续型流程生产自动控制（PA）或习惯称之谓工业过程控制中，有三大控制系统，即PLC、DCS和FCS。它们各自的基本特点如下：
   1 PLC 
 
    （1）从开关量控制发展到顺序控制、运送处理，是从下往上的。
    （2）连续PID控制等多功能，PID在中断站中。
    （3）可用一台PC机为主站，多台同型PLC为从站。
    （4）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。
    （5）PLC网格既可作为独立DCS/TDCS，也可作为DCS/TDCS的子系统。
    （6）大系统同DCS/TDCS，如TDC3000、CENTUMCS、WDPFI、MOD300。
    （7）PLC网络如Siemens公司的SINEC—L1、SINEC—H1、S4、S5、S6、S7等，GE公司的GENET、三菱公司的MELSEC—NET、MELSEC—NET/MINI。
    （8）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。
    （9）制造商：GOULD（美）、AB（美）、GE（美）、OMRON（日）、MITSUBISHI（日）、Siemens（德）等。
