You can import all the messages from an Excel worksheet into a Historian server. You can,
however, only add messages to Historian; you cannot modify or remove them.
Procedure
Open an Excel worksheet.
Select Historian > Administration > Import Messages.
A message appears, asking you to confirm that you want to import
messages.
Select Yes to execute the import. A window appears when the operation is complete. Select OK to close the window.
A message appears, stating that the import is successful. If, however,
an error occurs in any line of the import, the whole import is
aborted.
