That should be no problem; the FENA-11 supports EtherNet/IP, ProfiNet, or Modbus/TCP depending on a parameter setting in the drive.
I haven't used them for quite a few years so I would have used the "generic module object" rather than an "EDS-based Add On Profile" that might be available today.
But you definitely don't need RSNetworx for EtherNet/IP, just RSLogix 5000 software for the CompactLogix.
