Resolution
The Ethernet id of InfinityControllers is not actually used during communication, the id is saved to the database for informational purposes only.
The id is saved to the database when the controller is first created and commissioned, if the controller is then replaced it is possible to have a mismatch between the value of the Ethernet id in the database and the live value as read from the controller. This mismatch in the Ethernet id can be corrected or safely ignored. It does not have an effect on system operation either way.
