Ugh! Ethernet is specifically designed to almost NEVER be deterministic.
For the most part, it is fast enough that if you coordinated the message flow,
and only had the control PC and the motion box there, it probably would
work. Even still, there would be network management software that
would be sending out multicasts saying "I'm so-and-so, and I'm here!"
every second or so, and that would cause an occasional collision.
