Hello!

 

I am working in a solution to query a PI Server to get raw values from a historical set of PI points from a VBA code. But I need to get a set of maximum number of 5000 points from this query (in order to display it to a external HMI interface - GE Proficy IFIX Trend display)... so I want that the received data presents the requested timeframe completely.

 

Do you have a specific function to query the PI server requesting a number specific of points for a PI point?

 

Thanks in advance for your support!
