I have successfully built and configured master, ethercat drivers and
linuxcnc-ethercat and applied the pll timing patch on debian buster.
Converting and existing machine. Ethercat working, all io boards
talking....Ethercat here we go!
The next step was to configure the SDO's on the beckhoff AX5000 drives. So
naturally I loaded up the Twincat on windows and exported the xml
configurations for the drives.
After configuring the slaves to use the initialization xml from twincat, I
get errors and the drives won't go into operational mode.
After half a day of hair pulling I think that I found out that the byte
ordering from twincat xml files is little endian (intel byte ordering) and
that linuxcnc-ethercat takes data in big endian (network) endian. Yes I
read through the epic 10000 post forum thread to find this out.
Is that correct? If I reverse the data values in the sdo config to big
endian my drives will initialize?
Thanks,
Curtis
