1、 什么是DCS？
DCS是分布式控制系統(tǒng)的英文縮寫（Distributed Control System），在國(guó)內(nèi)自控行業(yè)又稱之為集散控制系統(tǒng)。
2、 DCS有什么特點(diǎn)？
DCS是計(jì)算機(jī)技術(shù)、控制技術(shù)和網(wǎng)絡(luò)技術(shù)高度結(jié)合的產(chǎn)物。DCS通常采用若干個(gè)控制器（過程站）對(duì)一個(gè)生產(chǎn)過程中的眾多控制點(diǎn)進(jìn)行控制，各控制器間通過網(wǎng)絡(luò)連接并可進(jìn)行數(shù)據(jù)交換。操作采用計(jì)算機(jī)操作站，通過網(wǎng)絡(luò)與控制器連接，收集生產(chǎn)數(shù)據(jù)，傳達(dá)操作指令。因此，DCS的主要特點(diǎn)歸結(jié)為一句話就是：分散控制集中管理。
3、 DCS的結(jié)構(gòu)是怎樣的？
DCS的控制決策是由過程控制站完成的，所以控制程序是由過程控制站執(zhí)行的。
5、 過程控制站的組成如何?
控制系統(tǒng)需要建立信號(hào)的輸入和輸出通道，這就是I/O。DCS中的I/O一般是模塊化的，一個(gè)I/O模塊上有一個(gè)或多個(gè)I/O通道，用來連接傳感器和執(zhí)行器（調(diào)節(jié)閥）。
7、 什么是I/O單元？
I/O單元與CPU是通過現(xiàn)場(chǎng)總線連接的。
