在工業(yè)生產(chǎn)過程中,1969年面世的plc和1975年面世的DCS可能是兩類影響最為深遠的計算機操控系統(tǒng)。PLC 的面世替代了繼電器之類的器材,完成了開關(guān)量的連鎖操控、程序操控;DCS的面世替代了顯現(xiàn)儀、調(diào)節(jié)器之類的外表,完成了模擬量的指示、記載和PID回路調(diào)節(jié)等功能。20世紀80年代晚期,跟著計算機技能、通訊技能、集成電路技能、智能傳感器技能的開展而呈現(xiàn)的現(xiàn)場總線操控系統(tǒng)(Fieldbus Control System , FCS )改變了原有操控系統(tǒng)的構(gòu)造,使操控系統(tǒng)由關(guān)閉向敞開走出了主要的一步。20世紀90年代中期,以PC為根底的操控系統(tǒng)(PC-Based Control System,PCBCS)開始呈現(xiàn),不少專家以為它將是工業(yè)自動化范疇最具開展?jié)摿Φ男录寄埽麄儗CBCS 與PLC 、DCS、 (或許再加上FCS)并稱為工業(yè)生產(chǎn)過程三大(或四大)操控系統(tǒng)。甚至有人在四年以前的文章中就談到"多數(shù)人以為在往后十年內(nèi)PC操控將逐漸替代傳統(tǒng)的PLC或DCS"。而德國菲尼克斯(PHOENIX CONTACT)公司的專家介紹:簡直一切的咨詢機構(gòu)都以為到2005年,PC為根底的操控系統(tǒng)將占商場分額的50%以上。
