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_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
