PLC、DCS是由早期不同的產(chǎn)品形態(tài)和應(yīng)用場(chǎng)合逐步完善演化而來(lái)。

可以說(shuō)PLC由制造業(yè)的繼電器演化發(fā)展而來(lái)。

DCS是由過(guò)程控制的儀表發(fā)展演化而來(lái)。

各自產(chǎn)品有其自己的使用場(chǎng)合和特點(diǎn)，隨著技術(shù)的進(jìn)步、行業(yè)的相互滲透和競(jìng)爭(zhēng)的激烈。

PLC和DCS這兩種產(chǎn)品都在發(fā)展自己優(yōu)勢(shì)的同時(shí)向?qū)Ψ降臐B透。

應(yīng)該知道PLC的邏輯控制功能很強(qiáng)大，而回路控制則是不值一提的（可以看一看型號(hào)稍微老一點(diǎn)的PLC），而DCS系統(tǒng)正好相反。這是由于兩種系統(tǒng)的內(nèi)部處理機(jī)制的不同。

看看現(xiàn)在呢？

老牌的PLC廠商均涉及DCS應(yīng)用領(lǐng)域如西門子、羅克威爾，其系統(tǒng)不過(guò)是PLC加網(wǎng)絡(luò)加軟件加增強(qiáng)的控制器。

DCS廠商如霍尼維爾等其系統(tǒng)也融入了PLC，以增強(qiáng)其邏輯控制功能。

要注意一點(diǎn)PLC是一種控制器；

DCS是一種體系結(jié)構(gòu)是由控制器+IO采集+網(wǎng)絡(luò)+軟件等組成的系統(tǒng)。

SCADA系統(tǒng)是另一個(gè)概念，有另一種應(yīng)用需求所呈現(xiàn)的系統(tǒng)。
