    Accessing PI AF data using PI Cloud and Bandwidth Constraints

    sowthri

      Hi,

       

      When we subscribe PI AF data from a publisher, only AF hierarchy alone gets stored not the historical value(Tag value if it is a PI tag type attribute) in the subscribers AF database. correct me if I'm wrong.

       

      Consider subscribed element is having a PI tag type attribute and we would like to plot a trend or pull data into excel for last 3 months. A good amount of data needs to be pulled over from publishers PI server on an adhoc basis. Will it create a bandwidth issue or performance issue?

       

      Please clarify.
