What are the main principles of the RIO allen bradley network?

hi All
Would you be so kind and help me to understand how Rio - remote IO allen bradley network work?
what are its main principles ? what is the difference between basic and enhanced version?
Sadly google did not help much in finding this information.
Any help is welcomed!
Regards
 
An overview? Good luck, maybe someone else can come up with one.

A technical article on this site gives a perfunctory view of the Data Highway + network used by A-B RIO. The article mentions the Allen-Bradley Data Highway Installation manual.

Lots of details in the ControlLogix Data Highway Plus-Remote I/O Communication Interface Module manual.
