AXL F BK ETH - Config error

Hi,
i am trying to configure my AXL F BK ETH (FW 1.32) to be controlled via Modbus TCP.
I have disabled the Plug and Play Mode but the config did not get saved. I always get the message that the Bus config has changed:

If i then use the password and clear button its gets ACK but nothing happens, the message stays.

I tried to:
-Reset the controller to factory default
-Enable / Disable Plug an Play mode again
-Deleted the config with WinSCP/FTP from the BK
-Used Startup+

What am i missing?

Hi Tobias,

Please reset the bus head to the factory settings using the reset button, see instructions 11.2

Then read in the local bus devices again via plug-and-play mode.
All local modules must be energized when reading in.
Only when this has been completed, carry out further settings such as IP assignment.
