AC800M EthernetIP Comm to S500 I/O

We have a potential project where we would like to install an AC800M controller with remote I/O. We would like to use Ethernet IP I/O due to having other devices that are communicating via Ethernet I/P. i know there is not a solution using S800I/O via Ethernet I/P but is it possible to use the S500 I/O via Ethernet I/P. I have seen the S500 I/O used via Profibus to the AC800M but can't find anything using it with Ethernet I/P. We have also used third party I/O solutions via Ethernet I/P but would like to stick with a total ABB solution.

Any help is appreciated.

Thanks,
Mike
