Yes and there are hardware available http://www.microchip.com/wwwproducts/en/LAN9252 or Beckhoff and SPI may be used to communicate with slave controller. I do not have time right now but will probably add later on. During the mean time I could use SPI. First I have to learn more about Ethercat then I have todo hardware and then software, it will take quite a lot of time. SPI I already tried maybe a month or two ago but had to add a fourth signal to the insulation barrier, it will give me at least 5-10 times more bandwidth than needed so I could chose to stay.
