First circuit board I made had ordinary Ethernet. For Ethercat two ports are needed but hardware should be same, there are few chips available to chose from. This guy used a board from Beckhoff and did not make the circuit boards himself. I did not yet fully understand the concept of FFMU and sync manager. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
