There is no reason to use specific eth card. We are using typical Ethernet card and we don’t implement real time protocols such as EtherCAT. There is no need.
In our current product we are using UDP client-server connection. There are implemented various simply commands for configuration, simple movement and trajectory move, for ex. Home(axis), Jog(axis, speed). CSMIO has buffer which collects trajectory points. So, when we want to put a path, we have to send a set of trajectory points to CSMIO. This buffer is set to collect a points for 500 ms now. So if there will be a little pauses/errors on eth connection CSMIO have a little buffer and all will be ok. For me, most interesting thing is that in what method planner transfers trajectory to HAL layer. As you see I need points buffer. And sorry for my English. I hope it is intelligible to you.

I think the first thing to work out is how to get realtime access to the Ethernet port inside a HAL module. Do you recommend a specific Ethenet card? I can see that might make it easier. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
