FOUNDATION FIELDBUS INFORMATION

FOUNDATION fieldbus is an all-digital, serial, two-way, multidrop communication protocol that interconnects devices such as transmitters and valve controllers. It is a local area network (LAN) for instruments that enables basic control and I/O to be moved to the field devices. The Rosemount 848L uses FOUNDATION fieldbus technology developed and supported by Emerson Process Management and the other members of the independent Fieldbus Foundation.
