PROFIBUS DP (分散式週邊,Decentralized Peripherals)用在工廠自動化的應用中,可以由中央控制器控制許多的感測器及致動器,也可以利用標準或選用的診斷機能得知各模組的狀態。 PROFIBUS PA (过程自動化,Process Automation)應用在過程自動化系統中,由过程控制系統監控量測設備控制,是 本質安全 的通訊協定 [2],可適用於防爆區域(工业防爆危险区分类中的Ex-zone 0及Ex-zone 1)。 其物理層(纜線)符合IEC 61158-2,允許由通訊纜線提供電源給現場 …
In pursuit of this objective, PROFIBUS is enhanced by the Ethernet-based communication standard PROFInet. The use of open standards rather than proprietary solutions ensures long-term compatibility and ex-pandability - in other words - pro-tection of existing investment. This is a matter of key importance to the PROFIBUS User Organization.
