Measured variables via HART protocol

The following measured values are assigned to the device variables at the factory:
Device variable
Primary variable (PV)
Secondary variable (SV)
Tertiary variable (TV)
Quaternary variable (QV)
1) The PV is always applied to the current output.
2) The pressure is the calculated signal after damping and position adjustment.
3) The Sensor pressure is the raw signal of the measuring cell before damping and position adjustment.
The assignment of the measured values to the device variables can be changed in the
following submenu:
Application → HART output → HART output
In a HART Multidrop loop, only one device may use the analog current value for signal
transmission. For all other devices in the "Loop current mode" parameter, select the
Disable option.
