Block instantiation is done by the host control system or configuration tool, but
not all hosts are required to implement this functionality. Please refer to your
specific host or configuration tool manual for more information.
Virtual Communication Relationship (VCRs)
There are a total of 20 VCRs. One is permanent and 19 are fully configurable
by the host system. Thirty link objects are available.

Transducer blocks refer to "Foundation Fieldbus Block Information" on
page A-1. Reference information on the PID block can be found in the
Function Block manual document number 00809-0100-4783.
Resource Block (index number 1000)
The Resource Function Block (RB) contains diagnostic, hardware and
electronics information. There are no linkable inputs or outputs to the
Resource Block.
Sensor Transducer Block (index number 1100)
The Sensor Transducer Function Block (STB) temperature measurement
data, including sensor and terminal temperature, The STB also includes
information about sensor type, engineering units, linearization, reranging,
damping, temperature compensation, and diagnostics.
LCD Transducer Block (index number 1200)
The LCD Transducer Block is used to configure the LCD display.
