Sinumerik controlpanel with Linux CNC

Yes of course. Like on the 7 seg. LED displays..

Do you may have ideas how its possible to use this mpi bus type of panel?

Mpi has quite some common part with old profibus. Can't remember witch one is a subset of the other. Mpi is newer, think it has more possibilities.

As far a I could read MPI and PB profocols are mostly the same and only few bits should different. On the MPI HW side there is mostly no galvanic isolation as found in PB.

After lot of googling I think this is way over my head. As the programmer of pyprofibus stated this MPI connection will surely not work with his software. Wireshark will also not work. If my understanding is correct a RS485 sniffer tool is needed. Problem is also that I dont know how this would be used :/
So I am afraid I have to go the Mesa way...

Don't know how it is today, but in the old (Siemens) days these protokoll have been kept for few eyes only behind locked doors. I remember they are subset of the secret s5 programming interface.

Beckhoff manage both profibus and profinet.

Thats right, but those communication terminals are hard to get working with lcec first of all. Then on this particular machine I am using Mesa Hardware, so it´s also not the straight forward soution. Maybe in this case better to use sserial HW (maybe Mesa or even arduino/stm stuff with a matrix type panel).
Nevertheless it would be very interesting to get those types of panels working with lcnc.
