Parameterlijst voor Device revision 3.0
De volgende lijst bevat de belangrijkste parameters en de betekenis daarvan:
•
primary_value
– This is the process value after adjustment and Linearization with the status of the transducer
block
•
primary_value_unit
– Unit code of '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
– Unit code of '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
•

•
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

•
SUB_DEVICE_NUMBER
•
SENSOR_ELEMENT_TYPE
•
display_source_selector
– Selects the type of value, which is displayed on the indicating and adjustment module
•
max_peak_sensor_value
– Holds the maximum sensor value. Write access resets to current value. Unit derives from
'Sensor_range.unit'
•
min_peak_sensor_value
– Holds the minimum sensor value. Write access resets to current value. Unit derives from 'Sen-
sor_range.unit'
•
CAL_POINT_HI
– Min./max.-adjustment: Upper calibrated point of the sensor. It refers to 'Cal_level_hi'. The unit
is defined in 'Sensor_range.unit'hi
