Hi Florian;<br>
<br>
I've got your EtherCAT master up and running now and was able to
reproduce the error that Massimo reported. You were correct, this was
a problem with the mailbox information set in the EEPROM. <br>
<br>
Thanks very much for pointing this out. It will be corrected in all
future firmware versions.<br>
<br>

when I tested with Jim on the last EtherCAT Plugfest, we had to correct
the standard mailbox information in words 0x0018-0x001b, that was the
only thing to get it running.

Correct, in that case the [RT]xPdo categories are not mandatory and
moreover shouldn't be included, because the they will deprecate once the
PDO configuration is altered for the first time.

No, because the master reads the (dynamic) PDO configuration from the
SDOs 0x1c1x and the referenced objects.
As you probably know, Jim called me yesterday. He suggested to send me a
device for testing to eliminate this interoperability issues. The funny
thing is, that we were searching DC amps with EtherCAT interface for a
long time and we really could use two of them for one of our
applications! ;-)
