DCS一般都提供統(tǒng)一的數(shù)據(jù)庫。換句話說，在DCS系統(tǒng)中一旦一個數(shù)據(jù)存在于數(shù)據(jù)庫中，就可在任何情況下引用，比如在組態(tài)軟件中，在監(jiān)控軟件中，在趨勢圖中，在報表中 而PLC系統(tǒng)的數(shù)據(jù)庫通常都不是統(tǒng)一的，組態(tài)軟件和監(jiān)控軟件甚至歸檔軟件都有自己的數(shù)據(jù)庫。為什么常說西門子的S7 400要到了414以上才稱為DCS？因為西門子的PCS7系統(tǒng)才使用統(tǒng)一的數(shù)據(jù)庫，而PCS7要求控制器起碼到S7 414-3以上的型號。

S7200CPU中不需要編寫任何與通信有關的程序，只需要將要交換的數(shù)據(jù)整理到一個連續(xù)的V存儲區(qū)當中即可。如果需要在主站中（如S7-300）如何配置S7200CPUMPI從站的詳細文檔，可訪問客戶支持部網(wǎng)站上的“網(wǎng)上課堂"網(wǎng)頁，在“網(wǎng)絡（NET）"目錄中《S7-200與S7-300之間的通信》?，F(xiàn)場總線還可以處理復雜的事情：本質安全、危險場合、多變量的過程以及法規(guī)要求嚴格的環(huán)境。

西門子 6SL3246-0BA22-1BA0 G120控制單元：

PLC和工控機采用現(xiàn)場總線有以下益處：1、互操作性互操作性定義為在沒有任何功能損失的條件下，不同廠家的多個設備可以工作在一個系統(tǒng)中，互操作性允許工廠工程師可在相同的現(xiàn)場總線中集成不同廠家的設備，也允許工程師用別的廠家的設備來替換一臺現(xiàn)場總線設備。

2、更低的安裝費用現(xiàn)場總線將極大地降低工廠最初的費用，包括簡化接線、更少的接線端子排和簡化了的儀表選型。此外，減少的費用還有：簡化了圖紙、簡化了控制系統(tǒng)的工程實施、減少了用于連線、接線柜和接線盒的費用。通過把控制功能轉移到現(xiàn)場，控制系統(tǒng)的費用也降低了：減少了DCS所需的空間，減少了控制系統(tǒng)的I/O點數(shù)，減少了機柜的空間和I/O接線端子排。現(xiàn)場總線將能提供在線的遠方數(shù)字通訊，可用來實現(xiàn)更快的調(diào)試、更快的診斷，降低安裝和調(diào)試設備的人工費用。
