/** \file
* \brief
* General typedefs and defines for EtherCAT.
*
* Defines that could need optimisation for specific applications
* are the EC_TIMEOUTxxx. Assumptions for the standard settings are a
* standard linux PC or laptop and a wired connection to maximal 100 slaves.
* For use with wireless connections or lots of slaves the timeouts need
* increasing. For fast systems running Xenomai and RT-net or alike the
* timeouts need to be shorter.
