Access a Tag

About this task

Using Historian Administrator, you can access a list of tags in the Historian database by their name, description, or both.
Note: By default, maximum one million tags are retrieved. If the Historian clients are configured to retrieve more than a million tags, to retrieve all of them, add the MaxTagsToRetrieve registry key under HKEY_LOCAL_MACHINE\SOFTWARE\Intellution, Inc.\iHistorian\Services\DataArchiver\, and then set the maximum number of tags that you want to retrieve. Restart the Historian Data Archiver service for the change to reflect.
