一般一套DCS中要設(shè)置現(xiàn)場I/O控制站，用以分擔(dān)整個系統(tǒng)的I/O和控制功能。這樣既可以避免由于一個站點(diǎn)失效造成整個系統(tǒng)的失效，提高系統(tǒng)可靠性，也可以使各站點(diǎn)分擔(dān)數(shù)據(jù)采集和控制功能，有利于提高整個系統(tǒng)的性能。DCS的操作員站是處理一切與運(yùn)行操作有關(guān)的人機(jī)界面（HMI-Human Machine Interface或operator interface）功能的網(wǎng)絡(luò)節(jié)點(diǎn)。

20世紀(jì)80年代至90年代中期，是可編程邏輯控制器發(fā)展zui快的時期，年增長率一直保持為30~40%。在這時期，PLC在處理模擬量能力、數(shù)字運(yùn)算能力、人機(jī)接口能力和網(wǎng)絡(luò)能力得到大幅度提高，可編程邏輯控制器逐漸進(jìn)入過程控制領(lǐng)域，在某些應(yīng)用上取代了在過程控制領(lǐng)域處于統(tǒng)治地位的DCS系統(tǒng)。
　　20世紀(jì)末期，可編程邏輯控制器的發(fā)展特點(diǎn)是更加適應(yīng)于現(xiàn)代工業(yè)的需要。這個時期發(fā)展了大型機(jī)和超小型機(jī)、誕生了各種各樣的特殊功能單元、生產(chǎn)了各種人機(jī)界面單元、通信單元，使應(yīng)用可編程邏輯控制器的工業(yè)控制設(shè)備的配套更加容易。
