Re: [Emc-users] CANopen over Ethernet CiA 309

[Nicklas K. <nic...@gm...>]

I implemented an Ethercat master for linuxcnc and the messages sent in the
frames are CANopen. In Ethercat message is sent by master only and changed
while "shifted" thru the other devices.

Basically there is a need to insert CANopen messages into the messages at
least for configuration purposes and this is the reason I want to add a
standard gateway. It may also make sense if Linuxcnc is used for ordinary
CANopen network.
