Gregor, Yes I know that these are the times to use, but I was getting an error. It turns out that the problem was that there was no history for the base PIPoint.

Please note, physical distance between servers doesn't impact data collection but network will have an impact if servers are placed at distance isolated by network/security firewalls. Would prefer having…
