Retrieve number of values from PI tag

[DerRoedie73]

Hi,

I would like to know if PiConnect is able to retrieve a number of values from a PI-tag instead of the values between a start and end-date.
For an implementation I would always like to retrieve the last 15 values from any given PI-tag. Using the RecordedValues implementation I need to pass a start and end date, this is something I do not know, only the startdate which is always * (Now).

Any help or suggestions are much appreciated.

Thanks
