wikipedia explain better the difference between field bus .... ethercat is better but need ET110 on slaves nodes + master & master in same deasy chain it is not well digested .... powerlink not have the same performance because no particular chip is required on master or into slaves .... most masters are tolerated & GigaByte ethernet is implemented.
Says these, even these are things to consider .... anyway my idea of using cc-link ie is not bad either because the latest developments. when I turned Lcnc & powerlink together I will post the results on the forum. BUt I see that you try to implement canopen over rs422 mesa card? these is a nice project. bkt 2017-09-12 20:33 GMT+02:00 Nicklas Karlsson <[email protected]>: > > for work buy device in china every mount from 3 year ... so I have my > > little opinion ...
