Standardized designation of the physical design property of a sensor
(e.g., DP, AP for pressure TC, RTD for temperature.)
The continuous range of values in the "normal" operating range of PV
values (that is, URV-LRV).
A measured physical value of a physical property (e.g., temperature)
that relates to the measured primary physical property (e.g., pressure).
Standard scale of values of an SV, chosen by the user for convenient
display and interpretation.
Minimum value in the useful range of the physical property of a
transmitter sensor can operate.
Maximum value in a continuous range of "normal" process values.
Command from the HHC to copy the values of displayed parameters
to either the transmitter to which it is connected, or to (NV? memory)
in the HHC.
If XS Delta Detection is On and the Delta Alarm value is exceeded,
the PV output goes to the Failsafe value and a Critical Status message
is enunciated.
If Off and the Delta Alarm value is exceeded, the PV output is not
affected and a Non-Critical Status message is enunciated.
