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
-
Unit code of 'Primary_value'
-
%
l secondary_value_1
-
Process pressure. Selected as input to AIFB by setting 'Channel' = 2. Unit derives from
'S
econdary_value_1_unit'
l secondary_value_1_unit
-
Unit code of 'Secondary_value_1'
-
bar, PSI, …, m, ft, …; in case of length type engineering unit and access to parameters the
corresponding values will be converted by density factor
l secondary_value_2
-
Value after min/max-adjustment. Selected as input to AIFB by setting 'Channel' = 3. Unit derives
from 'Secondary_value_2_unit'
l secondary_value_2_unit
-
Selected unit code for "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'
