lue after min/max adjustment and Linearization with the status
of the transducer block. The unit is defined in "PRIMARY_VA-
LUE_UNIT"
PRIMARY_VALUE_UNIT Selected unit code for "PRIMARY_VALUE"
SECONDARY_VALUE_1 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"
SECONDARY_VALUE_1_
UNIT
Selected unit code for "SECONDARY_VALUE_1"
SECONDARY_VALUE_2 This is the distance value ("sensor_value") with the status of
the transducer block. The unit is defined in "SECONDARY_VA-
LUE_2_UNIT"
FILL_HEIGHT_VALUE Filling height. The unit is defined in "FILL_HEIGHT_VALUE_
UNIT"
FILL_HEIGHT_VALUE_UNIT Filling height unit
CONST_VALUE
