從開關(guān)量控制發(fā)展到順序控制、運(yùn)送處理，是從下往上的連續(xù)PID控制等多功能，PID在中斷站中。

　　可用一臺PC機(jī)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(gòu)成PLC網(wǎng)絡(luò)。這比用PC機(jī)作主站方便之處是：有用戶編程時，不必知道通信協(xié)議，只要按說明書格式寫就行。

　　PLC網(wǎng)格既可作為獨(dú)立DCS，也可作為DCS的子系統(tǒng)。

　　PLC主要用于工業(yè)過程中的順序控制，新型PLC也兼有閉環(huán)控制功能。

　　DCS：

　　分散控制系統(tǒng)DCS集4C（Communication，Computer， Control、CRT）技術(shù)于一身的監(jiān)控技術(shù)。

　　從上到下的樹狀拓?fù)浯笙到y(tǒng)，其中通信（Communication）是關(guān)鍵。

　　PID在中斷站中，中斷站聯(lián)接計算機(jī)與現(xiàn)場儀器儀表與控制裝置是樹狀拓?fù)浜筒⑿羞B續(xù)的鏈路結(jié)構(gòu)，也有大量電纜從中繼站并行到現(xiàn)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，由控制站掛到局域網(wǎng)LAN。

　　DCS是控制（工程師站）、操作（操作員站）、現(xiàn)場儀表（現(xiàn)場測控站）的3級結(jié)構(gòu)。用于大規(guī)模的連續(xù)過程控制，如石化等。
