Attached is a Codesys file that I made for the communication settings between a Fanuc R30iB Controller and a Opto 22 Groov Epic controller running on codesys. On the Fanuc side you will have to set up a Ethernet Adapter using 4 words, Set IP address on the same network, and the configure the I/O. You then should be good to go!
Hope this helps!
