HART device variables
The following measured values are assigned to the device variables at the factory:
Device variable
Measured value
Assign PV
Level linearized
Assign SV
Distance
Assign TV
Absolute echo amplitude
Assign QV
Relative echo amplitude
1)
The PV is always applied to the current output.
