產品名稱：AB DCS 系統(tǒng)模塊
產品型號：MPL-B660F-MJ74AA
產品參數(shù)：MPL-B660F-MJ74AA
產品功能：MPL-B660F-MJ74AA

2.DCS存在的問題
(1)1對1結構。1臺儀表，1對傳輸線，單向傳輸1個信號。這種結構造成接線龐雜、工程周期長、安裝費用高、維護困難。
(2)可靠性差。模擬信號傳輸不僅精確度低，且易受干擾。為此采用各種措施提高抗干擾性和傳輸精確度，其結果是增加了成本。
(3)失控狀態(tài)。操作員在控制室既不了解現(xiàn)場模擬儀表的工作狀況，也不能對其進行參數(shù)調整，更不能預測事故，導致操作員對其處于失控狀態(tài)。因操作員不能及時發(fā)現(xiàn)現(xiàn)場儀表故障，而發(fā)生事故已屢見不鮮。
(4)互操作性差。盡管模擬儀表已統(tǒng)一4～20mA信號標準，可大部分技術參數(shù)仍由制造商自定，致使不同品牌儀表無法互換。因此導致用戶依賴制造廠，無法使用性能價格比最優(yōu)的配套儀表，甚至出現(xiàn)個別制造商壟斷市場的局面。
