Reduced pressure
A standard control algorithm. Also refers to a PID function block.

Printed Wiring Assembly
Radio Frequency Interference
Resistance Temperature Detector
The software component that implement the Foundation Fieldbus
communications protocol specifications, including FMS, FAS, DLL, SM and
NM.
A coded value that qualifies dynamic variables (parameters) in function blocks.
This value is usually passed along with the value from block to block. Status is
fully defined in the FF FBAP specifications.
Pressure Transmitter Interface Module
Pressure Transmitter Interface Multivariable Input / Output Processor
Provides services that coordinate the operation of various devices in a
distributed fieldbus system.
Part of the device software that operates on system management objects.
A collection of objects and parameters comprising configuration and
operational information used for control of system management operations.
Technical Assistance Center
A selected reference point at which a measurement is calibrated.

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.
