計(jì)算機(jī)及網(wǎng)絡(luò)技術(shù)與控制系統(tǒng)的發(fā)展有著緊密的聯(lián)系。早在50年代中后期，計(jì)算機(jī)就已經(jīng)被應(yīng)用到控制系統(tǒng)中。60年代初，出現(xiàn)了由計(jì)算機(jī)完全替代模擬控制的控制系統(tǒng)，被稱為直接數(shù)字控制（DirectDigitalControl,DDC）。70年代中期，隨著微處理器的出現(xiàn)，計(jì)算機(jī)控制系統(tǒng)進(jìn)入一個新的快速發(fā)展的時期，1975年世界上套以微處理為基礎(chǔ)的分散式計(jì)算機(jī)控制系統(tǒng)問世，它以多臺微處理器共同分散控制，并通過數(shù)據(jù)通信網(wǎng)絡(luò)實(shí)現(xiàn)集中管理，被稱為集散控制系統(tǒng)

計(jì)算機(jī)控制系統(tǒng)也是經(jīng)歷了集中控制、分層控制、基于現(xiàn)場總線的網(wǎng)絡(luò)控制等幾個發(fā)展階段，它們的發(fā)展過程是非常相似的。

隨著企業(yè)信息網(wǎng)絡(luò)的深入應(yīng)用與日臻完善，現(xiàn)場控制信息進(jìn)入信息網(wǎng)絡(luò)實(shí)現(xiàn)實(shí)時監(jiān)控是必然的趨勢。為提高企業(yè)的社會效益和經(jīng)濟(jì)效益，許多企業(yè)都在盡力建立的管理信息系統(tǒng)，它必須包括生產(chǎn)現(xiàn)
