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.
