Point IO Fault 16#031C - Connection Request Error

I have a 1734 AENTR that has 18 point IO modules on a rack. Some of the modules on this point IO are working fine, but about five of the sinking inputs are giving me this fault. On another rack three analog input cards are giving me this exact fault as wel. I can't find anything that gives more information on this fault.

 

I don't believe it to be a networking issue, the Ethernet card itself isn't faulting out, just some of the input cards. Also, all the sinking input cards are configured identically, but some fault out, some don't.

 

 

 

Here is a screenshot of the rack and and the module fault for the analog inputs:
