INTERCONNECTED MODEL FOR FOUNDATION FIELDBUS H1 AND ETHERNET

This paper presents a interconnected model for foundation fieldbus low-speed bus H1 and ethernet based on the development of fieldbus. In the interconnected model, the Socket interface is adopted between Management Station on the LAN and link master device on the FF. Taking advantage of the Device Agent in the Link Master Device, we can also connect the Base Device to the Management Station. As for communication between the fieldbus devices, virtual communication relation is still used.
