Remarks
If the PISystem is currently connected to the PI AF Server (see PISystem.ConnectionInfo.IsConnected), then this method will save all modifications to the AFCollective to the PI AF Server. The Refresh method can be called before making any changes to the collective to ensure that it has the most recent changes.
If the PISystem is not currently connected to the PI AF Server, then this method will save the information to connect to the AFCollective locally on the client computer. The next time a connection is made to the PI AF Server, the information will be updated from the server.
