SLC 5/05 not recongnize ( Yellow question mark)

I configure the SLC 5/05 for Ethernet and it works fine (device = OK) . However, i don't have the PLC icon/symbol (comm setup or RSlinx )... instead it says unrecognized device type ( yellow question mark).
Any ideas on how to fix this ?

Thanks.

Could be RSLInx does not have the EDS file for SLC5/05 with Ethernet.

EDS Files link below. Hope it helps
