Access atribute values for event frames start and end times

Hello,

 

I have the following situation: I have certain event frames, which gives me start and end times. And I also have elements attributes that are configured with the PI Point data reference, with the Time Range retrieval method set to Average.

 

Is there a way for me to query these attributes using the time range of the event frames?

 

In a related issue, if I configure an attribute with the PI Point Data Reference, set the time method as not supported and set the time range method as average, how can I query the value of the attribute? I mean, how can I set a time range to the attribute via OLEDB Enterprise? I tried the transpose functions, but all of then get the attribute via the time method.

 

Hope I made myself clear, and thanks in advance.
