Possible. In either case, I don't believe it's a good idea to mix regular
Ethernet traffic with Real Time Machine control traffic. Think of the 7i92
ethernet link as a dedicated serial port connection no different than say an
SPI port or even Ethercat (I know very little about that).
For example I would use CAN bus for controlling relays, tool changers, pick and
place, punches, even press and shear operations etc. But I wouldn't use it
for real time closed loop motor control. It wasn't designed for that.
Keep the real time part separate from the user interface part.
