Description
PRIMARY_VALUE (Linearized value). This is the process va-
lue after min/max adjustment and Linearization with the status
of the transducer block. The unit is defined in "PRIMARY_VA-
LUE_UNIT"
Selected unit code for "PRIMARY_VALUE"
This is the measured value after min/max adjustment with the
status of the transducer block. The unit is defined in "SECON-
DARY_VALUE_1_UNIT"
Selected unit code for "SECONDARY_VALUE_1"
This is the distance value ("sensor_value") with the status of
the transducer block. The unit is defined in "SECONDARY_VA-
LUE_2_UNIT"
Filling height. The unit is defined in "FILL_HEIGHT_VALUE_
UNIT"
Filling height unit
Constant value
