I have a query makes with PIAdvCalcFilVal() in DAtaLink with few arguments but when i want to convert it into a PIPoint.FilteredSummaries()method in my Python script gives me errors.
have i to fill all attributes in PIPoint.FilteredSummaries method? if i dont want to fill all attibutes how i can do it with None??
And there are two AFTimeSpan as attributes... its the same time range?
