2、從系統(tǒng)結(jié)構(gòu)來說:
PLC與DCS的基本結(jié)構(gòu)是一樣的。PLC發(fā)展到今天,已經(jīng)全面移植到計算機系統(tǒng)控制上了,傳統(tǒng)的編程器早就被淘汰。小型應(yīng)用的PLC一般使用觸摸屏,大規(guī)模應(yīng)用的PLC全面使用計算機系統(tǒng)。和DCS一樣,控制器與IO站使用現(xiàn)場總線(一般都是基于RS485或RS232異步串口通訊協(xié)議的總線方式),控制器與計算機之間如果沒有擴展的要求,也就是說只使用一臺計算機的情況下,也會使用這個總線通訊。但如果有不止一臺的計算機使用,系統(tǒng)結(jié)構(gòu)就會和DCS一樣,上位機平臺使用以太網(wǎng)結(jié)構(gòu)。這是PLC大型化后和DCS概念模糊的原因之一。
3、PLC和DCS的發(fā)展方向:
小型化的PLC將向更專業(yè)化的使用角度發(fā)展,比如功能更加有針對性、對應(yīng)用的環(huán)境更有針對性等等。大型的PLC與DCS的界線逐步淡化,直至完全融和。
DCS將向FCS的方向繼續(xù)發(fā)展。FCS的核心除了控制系統(tǒng)更加分散化以外,特別重要的是儀表。FCS在國外的應(yīng)用已經(jīng)發(fā)展到儀表級??刂葡到y(tǒng)需要處理的只是信號采集和提供人機界面以及邏輯控制,整個模擬量的控制分散到現(xiàn)場儀表,儀表與控制系統(tǒng)之間無需傳統(tǒng)電纜連接,使用現(xiàn)場總線連接整個儀表系統(tǒng)。(目前國內(nèi)有橫河在中海殼牌石化項目中用到了FCS,儀表級采用的是智能化儀表例如:EJX等,具備先進的控制水準(zhǔn))。
○如何正確對待PLC和DCS
我個人從不強調(diào)PLC和DCS之間孰優(yōu)孰劣,我把它們使用了一個新名詞“控制類產(chǎn)品”。我們提供給用戶的是適合用戶的控制系統(tǒng)。絕大多數(shù)用戶不會因為想使用一套DCS而去使用DCS,控制類產(chǎn)品必須定位在滿足用戶的工藝要求的基礎(chǔ)之上。其實提出使用DCS還是PLC的用戶大抵是從沒接觸過自控產(chǎn)品或有某種特殊需求的。過分強調(diào)這個東東只會陷入口舌之爭。
從PLC與DCS之間的區(qū)別和共同之處我們了解了控制類產(chǎn)品的大抵情況。注意,作為專業(yè)人士,我們自己不要為產(chǎn)品下PLC還是DCS的定義,自己的心理上更不能把產(chǎn)品這樣來區(qū)別對待。
