模塊：DCS系統所有I/O模塊都帶有CPU，可以實現對采集及輸出信號品質判斷與標量變換，故障帶電插拔，隨機更換。而PLC模塊只是簡單電氣轉換單元，沒有智能芯片，故障后相應單元全部癱瘓。 
我們不得不從PLC和DCS的起源談起：PLC的發展基于制造業的現場控制需求，DCS大發展基于化工行業的連續過程控制和監控。從控制需求分類看，控制系統可分成：順序控制（PLC的基本功能）、過程控制（DCS）、位置控制（CNC）、傳動控制（調速或同步），但從發展的角度來看，這幾部分控制方式在漸漸融合。如果非要說出不同來，我認為有如下幾點： 
1、面向對象不同：PLC面向一般工控制領域，通用性強。DCS偏重過程控制，用于化工行業。 
2、DCS強調連續過程控制的精度，可實現PID、前饋、串級、多級、模糊、自適應等復雜控制，一般PLC僅具有PID功能，控制精度不如DCS高。
3、DCS系統具有功能強大的SCAND軟件包，具有配方功能，并針對不同行開發了專家軟件（化工工藝參數配置和控制算法），比PLC應用方便。聯系人：蘇寶珠電話：18050108292
