What is required for the source tag in a summarized tag for successful deletion?

For successful deletion of a summarized tag, it is necessary that the source tag associated with it cannot be deleted without first deleting the summarized tag. The summarized tag generally creates a dependency on the source tag in the database, meaning that the summarized tag relies on the data and structure of the source tag to function correctly. If you attempt to delete the source tag without removing the summarized tag first, you will encounter issues since the summarized tag requires the source tag for reference.

This dependency is crucial to maintain data integrity in the historian database, ensuring that summarized data remains accurate and reflects the underlying source data it is meant to represent. Therefore, proper deletion protocols must be followed to avoid compromising the database’s structure and accuracy.
