Hi Pi Users,
I've recently started using the PI Steam Functions in some ProcessBook trends via the PI calculations, i.e. StmSI_TsatP('12lba51cp901_xj60'*100) returns the sat temp for the tag 12lba51cp901_xj60 which is a steam pressure value. This works fine. I'm starting to develop my AF database and would like to be able to create an attribute called Tsat based either a formula or a PI analytics calculation using the original pressure tag attribute. I've had a play but can't seem to make it happen as the steam function doesn't seem to be recongnised. Maybe I'm doing it wrong, so all comments or instructions would be gratefully received.
Cheers,
