Sinumerik controlpanel with Linux CNC

Could you try one button and see if there is any reaction on one of the connectors ?

The MCP is sat in a box with no power to it - if you have a pin out I can check for continuity across a shortlist of pins of interest (for example), but I don't have enough play time to reverse engineer it by guessing.

See attached for details of MCP 398C.

PS - would assume X20/X21 are PROFINET.

wow that panel looks brand new !

The manuals can be found here:

These panels seem to come with several different interfaces some "user" buttons are directly available on individual pins some are matrix-keypads that can send HEX codes over USB then there is Profinet, step7 ...

It is (and already out of date!).

Profinet isn't very friendly (outside Siemens walled garden) as far as I know - I think Aciera is effectively advocating looking at older model MCPs.
