There is a wealth of information on the topic of connections in chapter 4 of this manual:
Ethernet Design Considerations
(15 MB PDF)
With a publication date of May 2013, it is a bit dated. For example it does not address Enhanced Rack Optimization that reduces the need for direct I/O connections to some analog and specialty I/O modules. Maybe there is a more recent reference document under a different title with this general content.
Thanks a lot Mispeld.
