Importing Tags

About this task

The Import Tags function permits you to move tag information into the Historian Server from an Excel Worksheet or from another system, which may be either local or remote.

When used with the Excel Add-In, the Import Tags function moves selected information from your current worksheet into the specified Historian Server. There is no error checking when you import tags through the Excel Add-In.

For example, with the Excel Add-In you can successfully import unsolicited tags without a calculation dependency (trigger). Historian Administrator prevents you from performing this import. As another example, the Excel Add-In allows you to import circular references, while Historian Administrator does not.
Note: Do not add or update the following spare configurations as the data may get corrupted or over written:
  • The Spare 1 field for OSI PI Distributor. OSI PI distributor reads data from the Historian tag displayed in the Tag Source Address field and sends it to the OSI PI tag name displayed in the Spare 1 field.
  • The Spare 5 field for Server to Server Collector and Server to Server Distributor as it is only used for internal purposes.

Procedure

  1. Select Administration and then select Import Tags from the Historian menu.
    A message box appears.
  2. Select Yes to initiate the operation.
    If successful, a window appears confirming completion of the import function.
  3. Select OK to close the window.
    If errors on the import occur, a window appears detailing the issues encountered during the import. If any error occurred with any line of the import, the whole import is aborted.
    Note: If you export all fields and attempt to import the read-only fields LastModified and LastModifiedUser, you may receive an Import failed, Error with Import Header message. Try exporting the tags again (not selecting the read-only fields) and importing.
