點擊圖片查看大圖現(xiàn)場總線不單單是一個通信標準，而是試圖包含全部領(lǐng)域，作為一個過程控制的開放的、集成的測量控制系統(tǒng)。采用現(xiàn)場總線，具有許多優(yōu)點：
a)大大縮減了鋪線費用；
b)簡化了線路的安裝與維護；
c)能傳送多個過程變量，可以實現(xiàn)在線故障診斷及線路故障檢測；
d)用數(shù)字信號取代4～20 mA模擬信號，可提高系統(tǒng)精度，而且可把一些功能(如線性化、補償校正、工程量轉(zhuǎn)換、報警處理等)賦于現(xiàn)場儀表，提高了現(xiàn)場儀表的自主性和可靠性；
e)因現(xiàn)場總線是雙向的，故可從控制室對現(xiàn)場儀表進行標定和調(diào)整；
f)現(xiàn)場總線采用國際標準后，用戶可以優(yōu)選各儀表廠商的產(chǎn)品組成系統(tǒng)，而不必考慮總線接口是否匹配問題。
