[etherlab-users] Ethercat/ProfiNet - add correct slave configuration to program

[Richard Hacker]

I am not sure where the problem is. Where did you get this CoE 
configuration from? Where did you get the PDO's from?

Increase the debugging:
# ethercat debug 1

or even
# ethercat debug 2
if you're brave in another step.
