If an InTouch application is connected to the Historian, what impact does it have on the tag import process?

When an InTouch application is connected to the Historian, the tag import process requires that the application be closed. This is essential because an active connection can interfere with the import process, leading to potential data inconsistency or corruption. If the application is running, it may be accessing and utilizing tags that the import process is trying to modify or add, which can result in conflicts.

Closing the application ensures that the Historian can safely update the tag information without any risk of interference. This ensures that all newly imported tags are correctly registered and available for use in the application once it is reopened.

In contrast, having an open application can compromise the integrity of the import process, which is why this is a required step for successful data assimilation into the system.
