　DCS為分散控制系統(tǒng)的英文（TOTAL DISTRIBUTED CONTROL SYSTEM）簡(jiǎn)稱。指的是控制危險(xiǎn)分散、管理和顯示集中。60年代末有人研制了作邏輯運(yùn)算的可編程序控制器（Programmable Logic Controller）。簡(jiǎn)稱PLC。主要應(yīng)用于汽車制造業(yè)。70年代中期以完成模擬量控制的DCS推向市場(chǎng)，代替以PID運(yùn)算為主的模擬儀表控制。首先提出DCS這樣一種思想的是原制造儀表的廠商，當(dāng)時(shí)主要應(yīng)用于化工行業(yè)。后又有計(jì)算機(jī)行業(yè)從事DCS的開發(fā)。
　　70年代微機(jī)技術(shù)還不成熟，計(jì)算機(jī)技術(shù)還不夠發(fā)達(dá)。操作站、控制器、I/O板和網(wǎng)絡(luò)接口板等都是DCS生產(chǎn)廠家自行開發(fā)的，也就是所有部件都是專用的。
