Restoring the Module Name
When restoring a module, make sure that the restored module’s name is the same as
the original module’s name. When tags are transferred to FactoryTalk Historian SE,
the tags are appended with the module name. If the restored module’s name is
different, the same tags will be transferred again with a different name.
For example:

Tags from the module FTHME1 are being transferred to FactoryTalk Historian
SE. When transferred, the module name is added to the tag name (e.g.,
FTHME1.<tag_name>).

FTHME1 is backed up and restored. However, the module name is now
FTHME2. The same tags that were already transferred will be transferred again
because now their tag name is FTHME2.<tag_name>. These duplicate tags will
be counted against your allotted number of points.
To avoid this issue, ensure that the restored module’s name is correct after the
restoration process. Click Advanced in the main navigation bar, and then click
System Settings
in the left navigation bar to view the module name.
