Parameterliste

Die folgende Liste enthält die wichtigsten Parameter und ihre Bedeutung:

•

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 'Secon-

dary_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

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 deri-

ves 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-specic error"" 17: ""Cal span too small"" 34: ""EEPROM memory fault""

36: ""ROM memory fault"" 37: ""RAM memory fault"" 40: ""non-specic hardware fault"" 41:

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

error"" 113: ""Communication hardware fault"""
