Hi Florian,

i found my (newbie-)mistakes.
As the mini example started the numbering of the slaves with 1 i did it 
the same way, and i had absolutely no doubt that it will fit if its like 
in the example. So the master tried to configure slave in position 1 
while there was only one slave on position 0.
After that it worked and i was able to fix the remaining little things 
(corrupted frames, timed out frames,...).

Thank you for your patience.
