 RFID, NFC and UWB Module Guide

Follow Radio Remi as a new plant device has the label of a valid unit but the key record of a retired one.

  1. Radio Remi watches the new device send a join request to the gateway.

    A new field device asks to join the plant network.

  2. Remi compares the label with the retired unit's key record and finds the mismatch.

    Its label looks right, but its key belongs to an old unit.

  3. Radio Remi observes as the gateway closes the join path and writes a review record; it does not admit the device.

    The gateway refuses the wrong identity and saves a clear record.

  4. Remi runs the valid join separately and marks broader plant security as unproved.

    A known good device still joins, so the test has a clear limit.

A new plant device has the label of a valid unit but the key record of a retired one.
