[etherlab-users] Timeout while checking SDO dictionary...

[Hobin Yoon]

Hello,

I've succeeded in running mini on Beckhoff EL9820. But failed to run
our in-house test board. It has ESC FB1111-0140. I got the following
SDO dictionary error. When I run mini, it can't get any data in cyclic
operation. Can somebody help me figure out what it means and how to
solve it? Plz shed some light. Thank you.

After the slave connected:
