L ista dei parametri
La seguente lista contiene i principali parametri e il loro significato:
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'
