Sometimes, data must be transmitted and received in a more precise way that a normal Ethernet could ever do. You see, those robotics people think “realtime” means to have a message delivered within a millisecond.
In my system I know where the bits are down to five picoseconds. This requires technology that is a tad more complex than just throwing a dumb PC at the problem (even if it runs Linux).
