Hi All
I'm having a real problem where the machine loses all slaves modules,
but I can not find any reason for this. The are no cable issues or
packet error that I can see.
We are using the generic interface and our scan rate is 1000/sec, the
machines runs happy for sometimes hours/a full day then suddenly it will
say 0 slaves responding. Our code will then stop scanning the bus as a
safety step.

Jul 29 09:59:57 SixHeadGrab kernel: [176457.840059] EtherCAT 0: 0
slave(s) responding on main device.
We get very few UNMATCHED datagrames but do get the on occasion. As you
can see they do not match up as there is almost 5 minutes between the
last UNMATCHED and the lost of the IO.
I'm looking for ideas on what can cause this or what steps I might take
to identify the issue.
Thanks
Mike
