Why are there very few if any ethernet ip sensors like devicenet had.
Devicenet has intelligent sensors that give angle of limit switches,Photoelectric sensors that give lens dirty indication,etc.
Ethernet ip all you have is cameras an few encoders and pneumatic and on machine io blocks.
Ethernet should be able to have a cable with comms and power wires becase ethernet has POE. So the 24 vdc should not be a problem.I know the limitations of POE and that is not what i am proposing but seperate 24 dc wires in the cable like devicenet.
I have to use devicenet and ethernet on equipment. It would be nine to have all ethernet and 1 network.
I was just curios why this is not being done? are there limitations that i am not aware of?
