The EtherNet/IP Communication Auxiliary Module is available as a single
Ethernet port (Cat. No. 193-DNENCAT) and dual Ethernet port (Cat. No.
193-DNENCATR) module that has RJ45 ports to connect to Ethernet cable
CAT5 type or better. Rockwell Automation offers a wide variety of
Allen-Bradley Ethernet patch cables with its Bulletin 1585 line of Ethernet
cables ( http://ab.rockwellautomation.com/Connection-Devices/RJ45-
Network-Media ).
Both the 193-DNENCAT and 193-DNENCATR devices support a Star
Ethernet topology in which all Ethernet nodes wire back to a central Ethernet
switch, hub, or router as shown in Figure 5 .

Rockwell Automation also offers a line of managed and unmanaged
Allen-Bradley Ethernet Switches with its Stratix™ family of Ethernet switches.

Ethernet-IP-Network for more information.
The Cat. No. 193-DNENCATR Module also supports a Ring Ethernet
topology in which all Ethernet nodes are wired in series with one another until
a complete network ring is made as shown in Figure 6 on page 17 .
