Hello Lukas,

the EtherCAT slave firmware for the NetX from Hilscher has some
problems in working with the IgH master. The main issues are
the (mostly) missing slave information in the (emulated) EEPROM of
the NetX and the fact that the NetX only supports LRD/LWR datagrams
(instead of LWR) which the igh master does not.
If your are interested in the details, read my posts on this list:
or in the Hilscher forum concerning some of these things:

If you're interested, I can send you a patch for the master enabling
communication with the NetX. I think I've posted it before on this
list but that was probably for some older NetX EC slave firmware, so it
will not work anymore.
But this patch is just a workaround. Imho it would be a better solution
implementing the optional LRD/LWR datagram types in the IgH master and
to bug Hilscher as to implement a clean SII interface in their NetX

Best regards
