DCS自1975年問世以來，已經(jīng)經(jīng)歷了二十多年的發(fā)展歷程。在這二十多年中，DCS雖然在系統(tǒng)的體系結(jié)構(gòu)上沒有發(fā)生重大改變，但是經(jīng)過不斷的發(fā)展和完善，其功能和性能都得到了巨大的提高�？偟膩碚f，DCS正在向著更加開放，更加標(biāo)準(zhǔn)化，更加產(chǎn)品化的方向發(fā)展。
作為生產(chǎn)過程自動化領(lǐng)域的計算機(jī)控制系統(tǒng)，傳統(tǒng)的DCS僅僅是一個狹義的概念。如果以為DCS只是生產(chǎn)過程的自動化系統(tǒng)，那就會引出錯誤的結(jié)論，因為現(xiàn)在的計算機(jī)控制系統(tǒng)的含義已被大大擴(kuò)展了，它不僅包括過去DCS中所包含的各種內(nèi)容，還向下深入到了現(xiàn)場的每臺測量設(shè)備、執(zhí)行機(jī)構(gòu)，向上發(fā)展到了生產(chǎn)管理，企業(yè)經(jīng)營的方方面面。傳統(tǒng)意義上的DCS現(xiàn)在僅僅是指生產(chǎn)過程控制這一部分的自動化，而工業(yè)自動化系統(tǒng)的概念，則應(yīng)定位到企業(yè)全面解決方案，即total solution 的層次。只有從這個角度上提出問題并解決問題，才能使計算機(jī)自動化真正起到其應(yīng)有的作用。
