DCS在發(fā)展的過程中也是各廠家自成體系，但大部分的DCS系統(tǒng)，比如西門子、ABB、霍尼維爾、GE、施耐德等等，雖說系統(tǒng)內(nèi)部（過程級）的通訊協(xié)議不盡相同，但操作級的網(wǎng)絡(luò)平臺不約而同的選擇了以太網(wǎng)絡(luò)，采用標(biāo)準(zhǔn)或變形的TCP/IP協(xié)議。這樣就提供了很方便的可擴展能力。在這種網(wǎng)絡(luò)中，控制器、計算機均作為一個節(jié)點存在，只要網(wǎng)絡(luò)到達的地方，就可以隨意增減節(jié)點數(shù)量和布置節(jié)點位置。另外，基于windows系統(tǒng)的OPC、DDE等開放協(xié)議，各系統(tǒng)也可很方便的通訊，以實現(xiàn)資源共享。

從數(shù)據(jù)庫來說。
DCS一般都提供統(tǒng)一的數(shù)據(jù)庫。換句話說，在DCS系統(tǒng)中一旦一個數(shù)據(jù)存在于數(shù)據(jù)庫中，就可在任何情況下引用，比如在組態(tài)軟件中，在監(jiān)控軟件中，在趨勢圖中，在報表中……而PLC系統(tǒng)的數(shù)據(jù)庫通常都不是統(tǒng)一的，組態(tài)軟件和監(jiān)控軟件甚至歸檔軟件都有自己的數(shù)據(jù)庫。為什么常說西門子的S7 400要到了414以上才稱為DCS？因為西門子的PCS7系統(tǒng)才使用統(tǒng)一的數(shù)據(jù)庫，而PCS7要求控制器起碼到S7 414-3以上的型號。
