this is sad ... 

in ethercat.org theres a point in the FAQ:

from there:
http://www.ethercat.org/en/faq.html#790

--------------------------------------------------------
3.4 How about Open Source? 

EtherCAT technology itself is not Open Source. Backed by the standardization 
of EtherCAT by IEC, ISO and SEMI, access to EtherCAT technology is available 
to everyone to non-discriminatory terms. Additionally, Master Licenses are 
free of royalties. Maintenance and all further development of the technology 
is available to all users by membership within the ETG, the user group for 
EtherCAT technology. If you have questions regarding implementing or using 
EtherCAT in conjunction with shared source or open source systems please 
contact ETG headquarters or Beckhoff, the EtherCAT technology licensor.
--------------------------------------------------------

I have asked, so when I got the answer I will inform.

regards,

Leopold
