　每個模件的I/O點數有8點和16點，很少使用32點模件。

    DCS的這種結構源于其使用領域主要在大型控制對象，19英寸標準機箱便于密集布置，較少的I/O點數則是由于對分散度的要求。PLC的大底版式機架，封閉式模件結構在管理和配置上更加靈活，單個設備的可靠性更高。因此，不少DCS也吸收了PLC在結構上的優點，采用了和PLC相似的封裝結構，如I/A采用金屬外殼，NETWORK-6000+采用導電塑料外殼。

    2．5、人機交互裝置在早期，DCS作為一個系統，其人機交互裝置是DCS廠家提供的專用裝置。而PLC廠家一般不提供人機交互裝置，往往由工程商自主采用通用的來完成(如ifix、intouch、組態王)。DCS集成的人機交互裝置往往有著功能較專業、穩定性較好的特點，但是其價格也很高。隨著PC技術的快速發展，一些通用發展很快，功能和性能逐漸超過了DCS廠家提供的專用裝置。因此不少DCS廠家逐步放棄了專用的人機交互裝置，轉而和PLC一樣也使用了通用的。DCS廠家使用通用并不是簡單地拼裝，而是在通用的基礎上，通過合作開發，將自已多年積累的網絡通訊技術、系統自診斷技術以專用軟件包的形式保留和繼承下來了。

例如，NT6000早期曾經使用過基于專用操作系統的T1000人機交互系統，而目前主要使用基于FIX/IFIX或INTOUCH的T3500人機交互系統。其中的LINPOLL網絡通訊包是開發集成的。

    3、DCS和PLC的市場情況和發展方向

    在熱工自動化領域，主廠房控制系統基本上毫無例外地使用DCS。而在輔助車間才使用PLC。其主要原因是早期的DCS系統非常昂貴，人們認為輔助車間的運行可以間斷，可靠性要求不是很高，且模擬量控制要求較少，從降低成本的角度出發，往往選擇PLC來構建控制系統。而鍋爐、汽機和發電機的控制系統，要求長期穩定可靠地運行，信號中含有相當比例的模擬量，從系統的性能出發，人們不得不選擇了昂貴的DCS。

    另外，分析一下主廠房DCS和輔助車間控制系統的市場競爭情況，我們會發現一個有趣的現象。主廠房DCS的競爭往往在不同品牌的供應商或代理商之間展開，競爭激烈,DCS的價格不斷下調。而輔助車間控制系統的競爭往往在同一品牌PLC的各個工程商之間進行，門檻較低，競爭更加激烈，但是PLC的價格下調幅度卻并不如DCS明顯。主要原因是DCS的生產商直接參與競爭，在巨大的市場壓力下，不斷下調設備制造費用和工程實施費用。而PLC的生產商不直接參與競爭，各個工程商只能下調自身有限的工程費用，空間有限。從現在情況看來，DCS與高檔PLC的價格差距已不明顯，輔助車間仍然較多地采用PLC，是市場的慣性使然。

    隨著國內電廠裝機容量的不斷擴大及電力系統改革的推進，對輔助車間控制的要求也不斷提高，在這個大環境，DCS系統進入輔助車間控制已成為趨勢。NT6000DCS因其綜合的技術經濟優勢，已經并將繼續在輔助車間控制方面發揮越來越大的作用。

    在輔助車間應用廣泛的PLC也并不會就此退出熱工自動化的歷史舞臺，前所未有的競爭壓力，將會促使PLC廠商在技術上向DCS標準靠攏，在價格上作出更大的努力。市場競爭的結果，

 

        將使用戶獲獲得更大的利益。

    4、結論

    DCS和PLC作為計算機技術和控制技術結合的產物，為火電廠熱工自動化水平的提高都作出了各自的貢獻。由于兩者在應用上有較大的相通性，在不同的時期，其各自的技術或價格優勢，都會直接影響到其市場地位。而市場的反應也會或快或慢地反映到各自的技術發展和價格調整上。從總的趨勢來看，DCS和PLC在技術上的融合和促進將會是競爭的主流，而在性價比方面，你來我往地不斷攀升，也將是發展的主旋律。<
