A defined communication endpoint. Fieldbus
communications can primarily only take place along an
active communications "path" that consists of two VCR
endpoints.
A logical grouping of "user layer" functions. Function blocks
are grouped into a VFD, and system and network
management are grouped into a VFD.
For example, to establish communications between a
transducer block and a function block, a VCR must be
defined at the transducer block and a VCR must be defined
at the function block.
