PI Buffering - Buffering of Performance Equations?

Hello Everyone,

 

I am little confused about the buffering of performance equations. The behavior i am observing in my system here is that performance equations are not being calculated if the connection to historian server is down but the instrument tag in the performance equation does get buffered so if i see the trend of calculated tag i will see a straight line between down period.

 

Is this a standard behavior or something is wrong with the configuration?

 

Thanks.
