I give up on ordinary Ethernet, Sercos might be good but no one seems to care so Ethercat seems to be the choice. > Talk about cables.

Might be good for them but where do I earn my money? To use my chain saw and sell trees is an option but I avoid it if possible, machines earn more money per hour if there is enough trees. ------------------------------------------------------------------------------ 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 [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
