Ah, but your challenge to the poster was to quote these items on Ethernet.
The poster was talking about large commercial ships, which have lots of
Ethernet things, now, from the communications devices back to the company
to the engine control room.

I know that too. Mostly Modbus or Fieldbus over either serial or ethernet.
But even there, the smallest devices only have serial interfaces.So a lot of
money goes into the serial to ethernet converters.
