Troubleshooting Tag Imports

If you experience problems with tag imports and want to resolve them, check the following:

• If you remove or add Historian Servers and attempt to search for tags, the Historian Excel Add-In may not recognize the default server and may display a message stating that the default server has not been set. To correct this, close and reopen the Search Tags dialog box.
• Make sure that you are not trying to import the Calculation Execution Time, Last Modified, or Last Modified User fields for each tag. These fields are read-only. As such, you can export them but can not import them.
• Check that your collector does not contain any duplicate tagnames. Duplicate tagnames will cause errors to occur.
• Verify that the number of tags that you want to import does not exceed the maximum licensed tag count. If it does, you will not be able to import the tags.
