True or False: If a change has been made to an imported tag in Historian, the tag's configuration will always be overwritten during the reimport.

The statement is false because when you reimport tags into the AVEVA Historian Server, the behavior regarding configuration changes depends on specific conditions and settings within the system. In most setups, if a tag has been modified after its initial import, those changes can be retained during the reimport process if the configuration is designed to allow for such behavior.

In particular, the Historian often provides options for how to handle existing tags during import, such as preserving user-defined changes or allowing for the retention of settings that were manually adjusted after the initial import. This means that an imported tag's configuration will not necessarily be overwritten if there have been changes made.

Thus, the correct understanding is that modifications to the tag's configuration by users can be kept despite the reimport, providing flexibility and preventing unintended loss of configurations that have been adjusted for operational needs.
