Typically you have to pay Rockwell and sign a licensing agreement to see the details of Allen-Bradley Remote I/O protocol. In return, they usually assign a technical support person who can help you out when you get stuck using their chipset ("node adapter").
At least one other company has reverse engineered the protocol, and then ended up signing a licensing agreement with Rockwell to avoid nasty legal costs.
Sincerely,
