它是作為德國國家標準和歐洲國家標準的現場總線標準。該項技術是由西門子公司為主的十幾家德國公司、研究所共同推出的。它采用OSI模型的物理層、數據鏈路層?,F場總線信息規(guī)范(FMS)型則只隱去了OSI標準的第三至第六層,采用了應用層。
它是由美國Echelon公司于1990年正式推出的。它采用ISO/OSI模型的全部7層協(xié)議,采用了面向對象的設計方法,通過網絡變量把網絡通信設計簡化為參數設置,其最大傳輸速率為1.5Mbps,傳輸距離為2700m,傳輸介質可以是雙絞線、光纜、射頻、紅外線和電力線等。

最早由德國BOSCH公司推出,用于汽車內部測量與執(zhí)行部件之間的數據通信。CAN結構模型取ISO/OSI模型的第1、2、7層協(xié)議,即物理層、數據鏈路層和應用層。
此外還值得一提的是,可尋址遠程傳感器數據公路(Highway Addressable Remote Transducer,HART)協(xié)議,它是由美國Rosemount公司最早推出的一種兼容4~20mA模擬信號和調制數字信號的現場總線協(xié)議。其數字通信由于采用調制/解調方式,屬于模擬系統(tǒng)向數字系統(tǒng)轉變過程中的過渡產品,因而在當前的過渡時期具有較強的競爭力,得到了較快的發(fā)展。
