計算機(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)實現(xiàn)實時監(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)場的實時數(shù)據(jù)信息，以確保實時掌握生產(chǎn)過程的運行狀態(tài)，使企業(yè)管理決策科學(xué)化，達(dá)到生產(chǎn)、經(jīng)營、管理的化狀態(tài)。信息一控制一體化將為實現(xiàn)企業(yè)綜合自動化CIPA（computerintegratedplantautomation）和企業(yè)信息化創(chuàng)造有利條件。
企業(yè)信息網(wǎng)絡(luò)與控制系統(tǒng)在體系結(jié)構(gòu)發(fā)展過程上的相似性不是偶然的。在計算機(jī)控制系統(tǒng)的發(fā)展過程中，每一種結(jié)構(gòu)的控制系統(tǒng)的出現(xiàn)總是滯后于相應(yīng)計算機(jī)技術(shù)的發(fā)展。實際上，大多數(shù)情況下，正是在計算機(jī)領(lǐng)域一種新技術(shù)出現(xiàn)以后，人們才開始研究如何將這種新技術(shù)應(yīng)用于控制領(lǐng)域。鑒于兩種應(yīng)用環(huán)境的差異，其中的技術(shù)細(xì)節(jié)作了適當(dāng)修改和補(bǔ)充，但關(guān)鍵技術(shù)的原理及實現(xiàn)上，它們有許多共同的地方。正是由于二者在發(fā)展過程中的這種關(guān)系，使得實現(xiàn)信息一控制一體化成為可能。
