DCS安全性：為保證DCS控制的設(shè)備的安全可靠，DCS采用了雙冗余的控制單元，當(dāng)重要控制單元出現(xiàn)故障時(shí)，都會(huì)有相關(guān)的冗余單元實(shí)時(shí)無擾的切換為工作單元，保證整個(gè)系統(tǒng)的安全可靠。PLC所搭接的系統(tǒng)基本沒有冗余的概念，就更談不上冗余控制策略。特別是當(dāng)其某個(gè)PLC單元發(fā)生故障時(shí)，不得不將整個(gè)系統(tǒng)停下來，才能進(jìn)行更換維護(hù)并需重新編程。所以DCS系統(tǒng)要比其安全可靠性上高一個(gè)等級(jí)。

模塊：DCS系統(tǒng)所有I/O模塊都帶有CPU，可以實(shí)現(xiàn)對(duì)采集及輸出信號(hào)品質(zhì)判斷與標(biāo)量變換，故障帶電插拔，隨機(jī)更換。而PLC模塊只是簡(jiǎn)單電氣轉(zhuǎn)換單元，沒有智能芯片，故障后相應(yīng)單元全部癱瘓。
