Synchronizing Devices with HART Device Tag Display Format
The same Device Tag Extension Mode needs to be set on PRM and FieldMate. Even if the user
renames the device tag on one side, it is updated to the other side after the synchronization as
long as the HART Device Tag Display Format of the device is consistent with the HART Device
Tag Display Format on the other side.
Sample case is shown as below, if HART Device Tag Display Format is set to “Tag+Descriptor”
and all the devices in the database are registered or updated with the same mode, then the
following outcomes can be expected.

Registering devices using PRM/FieldMate Synchronization means that the devices do not exist
in PRM database originally and the devices are imported from FieldMate.
In HART Device Tag Display Format is enabled, it can be expected that the device tags of the
devices imported to PRM do match the device tags shown in FieldMate.
However, if the HART Device Tag Display Format of the device in the database does not match
the mode of the other side, then the synchronization of the device is prohibited.
