Remarks
If changes are being made too quickly to the list of known PI Data Archive servers, the collection may not be able to keep up with the changes. This method can be called to make sure the collection is up-to-date.
Calling one of the PISystems.Refresh Overload methods will also refresh this collection of PIServer objects.
