Interaction of HART variables and transmitter outputs
The HART variables are automatically reported through specific transmitter outputs. They
may also be reported through HART burst mode, if enabled on your transmitter.
HART variables and transmitter outputsTable 6-13:
HART variable Reported via Comments
Primary Variable (PV) Primary mA output If one assignment is changed, the other is changed auto-
matically, and vice versa.
Secondary Variable (SV) Not associated with an out-
put
The SV must be configured directly, and the value of the
SV is available only via digital communications.
Tertiary Variable (TV) Frequency output (if
present on your transmitter)
If one assignment is changed, the other is changed auto-
matically, and vice versa. If your transmitter does not have
a frequency output, the TV must be configured directly,
and the value of the TV is available only via digital commu-
nications.
Quaternary Variable (QV) Not associated with an out-
put
The QV must be configured directly, and the value of the
QV is available only via digital communications.
