l 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'

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

'Secondary_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

'Sensor_range.unit'

l 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

l simulate_primary_value

l simulate_secondary_value_1

l simulate_secondary_value_2

l device status

- "0: ""OK"" 13: ""non-speciﬁc error"" 17: ""Cal span too small"" 34: ""EEPROM memory fault"" 36:

""ROM memory fault"" 37: ""RAM memory fault"" 40: ""non-speciﬁc hardware fault"" 41: ""Sensor

element not found"" 42: ""No leaking pulse"" 43 : ""No trigger signal"" 44: ""EMI error"" 113:

""Communication hardware fault"""

l linearization type

- Possible types of linearization are: linear, user deﬁned, cylindrical lying container, spherical

container

- "0: ""Linear"" 1: ""User def"" 20: ""Cylindrical lying container"" 21: ""Spherical container"""

l curve_points_1_10

- X and Y values for the user deﬁned linearization curve

l curve_points_11_20

- X and Y values for the user deﬁned linearization curve

l curve_points_21_30

- X and Y values for the user deﬁned linearization curve

l curve_points_31_33

- X and Y values for the user deﬁned linearization curve

l curve status
