[etherlab-users] Beckhoff EL3104 - Problem while setting OP state

[Matthieu Bec]

Hello Philippe,

One odd thing is you're giving PERIOD_NS to sync0 and sync1.
I'm not sure what's the effect of that, could be your issue.
The vanilla dc_user example does:
   ecrt_slave_config_dc (..., period0_val, shift0_val, 0,0);

Matthieu
