Ellistadosiguientecontienelosparámetrosmásimportantesysusignicado:
•
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
