Foundation Fieldbus is the basis for modern
control and automation products.
 Advanced functions added to field
instruments
 Expand view for the operator
 Enable migration of functions the field
 Reduce wiring and installation costs
 Reduce I/O equipment by one-half or
more
 Provide increased information flow to
enable automation of engineering,
maintenance, and support functions

Interoperability Allows...
 Devices from different manufacturers are able
to interact with each other without Host
interaction
– Control in the field works seamlessly
– Devices do not conflict with each other
 Host can read/write the resource and
transducer block parameters
 Device diagnostics may be accessed by the
host
