Measured variables via HART protocol
The following measured values are assigned to the device variables at the factory:
Device variable
Measured value
Primary variable (PV)
parameter (Primary variable)
Level limit detection
Secondary variable (SV)
parameter (Secondary variable)
Sensor frequency
Tertiary variable (TV)
parameter (Third variable)
Fork state
Quaternary variable (QV)
parameter (Quaternary variable)
Sensor temperature
1)
Primary variable (PV)
parameter is always applied to the current output.
2)
Level limit detection is the initial state depending on the fork state (uncovered/covered) and the safety
function (MIN/MAX)
3)
Sensor frequency is the oscillation frequency of the fork
4)
Fork state is the fork state (Fork covered/Fork uncovered)
The assignment of the measured values to the device variables can be changed in the
following submenu:
Navigation: 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.
Navigation: Application → HART output → Configuration → Loop current mode →
Disable
