Parameter list
The following list contains the most important parameters and their meaning:
•
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
– Unit code of 'Primary_value'
– %
•
secondary_value_1
– Process pressure. Selected as input to AIFB by setting 'Channel' = 2. Unit derives from 'Sec-
ondary_value_1_unit'
•
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 cor-
responding 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
•
simulate_primary_value
•
simulate_secondary_value_1
•
simulate_secondary_value_2
•
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"""
•
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"""
