Secondary variable (SV)
The secondary variable maps the second variable of the transmitter. This variable is a HART
only variable and can be read from the HART signal with a HART enabled input card, or can
be burst for use with a HART Tri-Loop to convert the HART signal to an analog output.
Options available for mapping to this variable can be found in
Tertiary variable (TV)
The tertiary variable maps the third variable of the transmitter. This variable is a HART only
variable and can be read from the HART signal with a HART enabled input card, or can be
burst for use with a HART Tri-Loop to convert the HART signal to an analog output. Options
available for mapping to this variable can be found in
.
Quaternary variable (QV)
The quaternary variable maps the fourth variable of the transmitter. This variable is a HART
only variable and can be read from the HART signal with a HART enabled input card, or can
be burst for use with a HART Tri-Loop
™
to convert the HART signal to an analog output.
Options available for mapping to this variable can be found in

Poll address
Poll address enables the transmitter to be used in point-to-point mode or multi-drop
mode. When in multi-drop mode, the poll address is used to identify each meter on the
multi-drop line.
The transmitter poll address is set to zero at the factory, allowing standard operation in a
point-to-point manner with a 4-20 mA output signal. To activate multi-drop
communication, the transmitter poll address must be changed to a non-zero integer; for
HART 5 between 1-15, for HART 7 between 1-63. This change fixes the analog output
current to 4 mA and disables the failure mode alarm signal.
