從開關量控制發展到順序控制、運送處理，是從下往上的連續PID控制等多功能，PID在中斷站中。
可用一臺PC機為主站，多臺同型PLC為從站。
也可一臺PLC為主站，多臺同型PLC為從站，構成PLC網絡。這比用PC機作主站方便之處是：有用戶編程時，不必知道通信協議，只要按說明書格式寫就行。
PLC網格既可作為獨立DCS，也可作為DCS的子係統。
PLC主要用於工業過程中的順序控制，新型PLC也兼有閉環控制功能。
DCS：
分散控制係統DCS集4C（Communication，Computer， Control、CRT）技術於一身的監控技術。
從上到下的樹狀拓撲大係統，其中通信（Communication）是關鍵。
PID在中斷站中，中斷站聯接計算機與現場儀器儀表與控制裝置是樹狀拓撲和並行連續的鏈路結構，也有大量電纜從中繼站並行到現場儀器儀表。
模擬信號，A/D—D/A、帶微處理器的混合。
一臺儀表一對線接到I/O，由控制站挂到局域網LAN。
DCS是控制（工程師站）、操作（操作員站）、現場儀表（現場測控站）的3級結構。用於大規模的連續過程控制，如石化等。
