IBS S7 400 DSC/I-T現(xiàn)貨

公司與國外的的制造商和企業(yè)有廣泛的技術與商務合作關系，我們國外直接供貨，省去中間流通環(huán)節(jié)，降低您的使用成本。

2、從系統(tǒng)結構來說:
PLC與DCS的基本結構是一樣的。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。小型應用的PLC一般使用觸摸屏，大規(guī)模應用的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)結構就會和DCS一樣，上位機平臺使用以太網(wǎng)結構。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在國外的應用已經(jīng)發(fā)展到儀表級。控制系統(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)。
○如何正確對待PLC和DCS
我個人從不強調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，控制類產品必須定位在滿足用戶的工藝要求的基礎之上。其實提出使用DCS還是PLC的用戶大抵是從沒接觸過自控產品或有某種特殊需求的。過分強調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品的大抵情況。注意，作為專業(yè)人士，我們自己不要為產品下PLC還是DCS的定義，自己的心理上更不能把產品這樣來區(qū)別對待。
