Ulrich,
You first have to set-up your AIM* historian instance to generate reduction
files. This is done by setting the following instance attributes:
REDUCLEVEL = 1
USEREDFILES = YES
Setting USEREDFILES = YES enables the use of the
reduction files by the extraction functions.
You also have to configure these instance attributes:
PCTVALID
REDUCPHASE
REDPHASEUNIT
SCANPEAKS
REDFASTUNIT
REDMEDUNIT
REDSLOWUNIT
REDFASTINT
REDMEDINT
REDSLOWINT
Regards,
Sylvain.

Subject: [foxboro] Data retrieval from reduction groups
Hi list,
how can I retrieve collected data from reduction groups, using FoxAPI
or AIMAPI? I don't want calculate the reduced values at runtime
(using fh_FdbReduction()). Is there a way to retrieve the already
collected reduced data?
Regards,
Ulrich
