I didn't have any luck with parsing the XML generated and exported from
TwinCAT unless I hand edited it. I found it much easier to just export
the EEPROM binary from TwinCAT, program the ESC, and then use the
'ethercat xml' command to generate the EtherCATInfo.xml file.

If that still doesn't work perhaps you could post your xml configuration
file.
