Hi everybody,
I have a problem with my EPOS3 controller. It seems to initialize fine but when
activationg "debug 1" a warning is already seen, regarding timed out and
unmatched datagrams. Is this a problem for later communication or normal? Where
could I further check? The results of dmesg are attached in the end of the mail.
The reason for my question is also the later communication. When trying to
further communicate with the device I get more errors. Again timed out
datagrams and SDO download is not possible.
I am also not quite sure what the error message means with "local control". Are
there options on the slave that have to be changed or is that something
regarding the master?
Thank you very much for any help!
