Changing the Base Name of Automatically Created Archives

About this task

When the IHC file is created, it stores the name of the server inside the IHC file. Automatically created archives use that server name from the IHC file as a base name, not the Base Archive Name configured in Historian Administrator.

When you manually create an archive, however, the archive uses the Base Archive Name from Historian Administrator.

If you move an IHC file from one machine to another, you may want to change the default base archive name to match the new server. To change the default Base Archive Name, create a new .IHC file.

Procedure

  1. Export your tags using the Excel Add-in.
    The Fields to Export window appears.
  2. Select all tag attributes and select OK.
    The data is exported to a new Excel worksheet.
  3. Examine the Comments column in the new worksheet. To ensure a clean import, the Comments column must be completely full or completely empty. If no comments are found, this column must be deleted to ensure a clean import. If only some comments are missing, the missing fields must be filled out with comments.
  4. Save the Excel spreadsheet.
  5. Stop the Historian Data Archiver service.
  6. Open the default archive path in Windows Explorer and rename the .IHC file.
    Rename MyMachine.IHC to MyMachine.OLD.
  7. Restart the Historian Data Archiver service.
    A new, blank IHC file is created for the machine.
  8. Import your tags to this new configuration using the Excel Add-In.
