The dialog box indicates the device name you assigned.

Forwarding the device name on replacement of the interface module
The device name of the IO device is saved to the MMC.
To transfer the name if the IM151-3 PN interface module is replaced, remove the
MMC from the ”old” IM151-3 PN and install it in the ”new” one.
It will import the device name from the MMC after the power to the IO device has
been switched off and on again. Then the station can be addressed again and will
operate in the same way as before the replacement.
Device flash test
When using more than one IO device, the system shows all of them in the Assign
device name dialog box. In this case, compare the MAC address of the device
with the indicated MAC address, then select the relevant IO device.
Identification of the IO devices is simplified by a device flash test. Enable the flash
test as follows:
1. Select one of the displayed IO devices in the Assign device name window.
2. Select the flash duration you want to use.
3. Press the Flash on button.
The LINK LED on the selected device flashes (open front doors of the
IM151-3 PN).
