OSIsoft vCampus is mainly covering development or integration-type questions around the PI System. Your question seem to be rather general and more related to the usage of one of OSIsoft interfaces to the PI Server. I would suggest you contact OSIsoft regular Tech Support for that matter. They are best trained and staffed to handle these end-user type questions.
But otherwise if you have any integration or development concerns or questions please feel free to follow up on this thread or start a new one. We would be happy to help
