[etherlab-users] Problem with BeckHoff EL4038 Terminal.

[Richard Hacker]

Look at the output of
$ ethercat slaves
The slave should be in OP when your model is running

What does your kernel log say:
$ cat /var/log/messages
or
$ dmesg | tail -100

What is the current configuration while running:
$ ethercat config -v -p1
