– bar, PSI, …, m, ft, …; in case of length type engineering unit and access to parameters the
corresponding values will be converted by density factor
•
secondary_value_2
– Value after min/max-adjustment. Selected as input to AIFB by setting 'Channel' = 3. Unit
derives from 'Secondary_value_2_unit'
•
secondary_value_2_unit
– Selected unit code for "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'
– includes sensor unit: bar, PSI …; only unit part of DS-68 is writable
