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)絡通訊中也已此模塊為單位進行傳遞,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、運行調(diào)試、遠程診斷方面,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)的遠程調(diào)試方案。
在網(wǎng)絡方面,DCS網(wǎng)絡是整個系統(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),采用的標準協(xié)議TCP/IP。它是安全可靠雙冗余的高速通訊網(wǎng)絡,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或上位機進行通訊時,所采用的網(wǎng)絡形式基本都是單網(wǎng)結(jié)構(gòu),網(wǎng)絡協(xié)議也經(jīng)常與標準不符。在網(wǎng)絡安全上,PLC沒有很好的保護措施。我們采用電源,CPU,網(wǎng)絡雙冗余.
