Listado de parámetros
El listado siguiente contiene los parámetros más importantes y su significado:
•
primary_value
– Process value after min/max-adjustment and linearization. Selected as input to AIFB by setting
'Channel' = 1. Unit derives from 'Primary_value_unit'
•
primary_value_unit
– Selected unit code for "primary_value"
•
secondary_value_1
– Value after min/max-adjustment (level + level offset). Selected as input to AIFB by setting
'Channel' = 2. Unit derives from 'Secondary_value_1_unit'
•
secondary_value_1_unit
– Selected unit code for "secondary_value_1"
•
secondary_value_2
– Sensor value + sensor offset. Selected as input to AIFB by setting 'Channel' = 3. Unit derives
from 'Secondary_value_2_unit'
•
secondary_value_2_unit
– Unit code of 'Secondary_value_2'
•
sensor_value
– Raw sensor value, i.e. the uncalibrated measurement value from the sensor. Unit derives from
'Sensor_range.unit'
•
sensor_range
– 'Sensor_range.unit' refers to 'Sensor_value', 'Max/Min_peak_sensor_value', 'Cal_point_hi/lo'
•
simulate_primary_value
•
simulate_secondary_value_1
•
simulate_secondary_value_2
•
device_status
•
Linearization Type
– Possible types of linearization are: linear, user defined, cylindrical lying container, spherical
container
•
curve_points_1_10
– X and Y values for the user defined linearization curve
•
curve_points_11_20
– X and Y values for the user defined linearization curve
•
curve_points_21_30
