Config-Problem Ethercat

Strang. minimal config works without problems.:
 
 


 full setup, sometimes it works, sometimes it doesn't 

 
 

is the problem because "dcconf"?

Yes, I see the difference in refclocksynccycles and assignActivate, that's most likely it.
I seem to recall the erc60 only works with DC sync mode, that is set assignActivate=300.
