Plan was to connect like shift register which should be very similar to Ethercat. What's worse is micro controller have FIFO so it is not possible to feed thru with good performance since virtual shift register length will be long in each device. Green LED should be possible also with daisy chain but there is a drawback all devices must work. Single chip will of course always work. For buses Ethercat for high bandwidth and CANopen for low bandwidth seems to be the choice. I think there is nothing wrong with Sercos but it seems to be more expensive for less performance.
