Parameter list
The following list contains the most important parameters and their meaning:
l primary_value
-
Process value after min/max-adjustment and linearization. Selected as input to AIFB by setting
'C
hannel' = 1. Unit derives from 'Primary_value_unit'
l primary_value_unit
-
Selected unit code for "primary_value"
l secondary_value_1
-
Value after min/max-adjustment (level + level offset). Selected as input to AIFB by setting
'C
hannel' = 2. Unit derives from 'Secondary_value_1_unit'
l secondary_value_1_unit
-
Selected unit code for "secondary_value_1"
l secondary_value_2
-
Sensor value + sensor offset. Selected as input to AIFB by setting 'Channel' = 3. Unit derives
from 'Secondary_value_2_unit'
l secondary_value_2_unit
-
Unit code of 'Secondary_value_2'
l sensor_value
-
Raw sensor value, i.e. the uncalibrated measurement value from the sensor. Unit derives from
'S
ensor_range.unit'
l sensor_range
-
'S ensor_range.unit' refers to 'Sensor_value', 'Max/Min_peak_sensor_value', 'Cal_point_hi/lo'
l simulate_primary_value
l simulate_secondary_value_1
l simulate_secondary_value_2
l device_status
