DCS經(jīng)過多年的發(fā)展，積累了大量的高級算法模塊。例如NETWORK6000+具有的設(shè)備級模塊，在一個模塊中集中完成了面向設(shè)備的基本控制和故障報警功能，在網(wǎng)絡(luò)通訊中也已此模塊為單位進(jìn)行傳遞，大大提高了軟件開發(fā)的效率。一個設(shè)備極模塊相當(dāng)于0.5K的梯形圖邏輯量，PLC要完成同樣的功能，就要煩瑣得多了。

在下載修改、運(yùn)行調(diào)試、遠(yuǎn)程診斷方面，PLC缺乏解決方案。而DCS從一設(shè)計之初就是從系統(tǒng)需要的角度出發(fā)的，有著多年積累的完善的解決方案。以NETWORK6000+DCS為例，系統(tǒng)既可以在線修改控制策略，也可以在線下載控制策略，修改和下載過程中，對系統(tǒng)的正常運(yùn)行沒有影響。NETWORK6000+DCS有完善的虛擬DCS功能，不但可以用于組態(tài)邏輯的驗證，而且能夠構(gòu)建成完整的虛擬DCS與模型相連，完成系統(tǒng)的仿真調(diào)試。NETWORK6000+DCS具有完善的安全措施，提供基于廣域網(wǎng)的遠(yuǎn)程調(diào)試方案。
在網(wǎng)絡(luò)方面,DCS網(wǎng)絡(luò)是整個系統(tǒng)的中樞神經(jīng)，和利時公司的MACS系統(tǒng)中的系統(tǒng)網(wǎng)采用的是雙冗余的100Mbps的工業(yè)以太網(wǎng)，采用的標(biāo)準(zhǔn)協(xié)議TCP/IP。它是安全可靠雙冗余的高速通訊網(wǎng)絡(luò)，系統(tǒng)的拓展性與開放性更好.而PLC因為基本上都為個體工作，其在與別的PLC或上位機(jī)進(jìn)行通訊時，所采用的網(wǎng)絡(luò)形式基本都是單網(wǎng)結(jié)構(gòu)，網(wǎng)絡(luò)協(xié)議也經(jīng)常與標(biāo)準(zhǔn)不符。在網(wǎng)絡(luò)安全上，PLC沒有很好的保護(hù)措施。我們采用電源,CPU,網(wǎng)絡(luò)雙冗余.
