Cia402 no connection

Hallo Hakan I supose that You are talking about this commands :sudo systemctl enable ethercat.service
sudo systemctl start ethercat.service
sudo systemctl status ethercat.service
sudo chmod 666 /dev/EtherCAT0
I try them before and also today but with no lack.
But I see that Oriental Motor unit catch a fault whenever I plug rj45 eth.
That situation never happen under twincat.
After summarize everything I wonder what do TwinCat that works properly .
I will try watch history fault in the driver ,maybe it can help.

Yes that was what I meant. 
Tips is to check what ethercat master writes in the syslog.

I see in the last screenshot it mentions MDI and MDI-X.
Can it be the cable, straight or crossed?

...unfortunately there is no fault in history alarm.
I'm using the same wire for connecting with twincat or with EK1100 where everything is working properly..
Tomorrow I will try to check sys log.
