EtherNet/IP Communications
Introduction The purpose of this chapter is to provide the necessary instructions to
successfully connect the E300™ Electronic Overload Relay EtherNet/IP
Communication Module (Catalog Number 193-ECM-ETR) to an Ethernet
network and configure it to communicate to an EtherNet/IP scanner such as an
Allen-Bradley Logix controller.
Network Design The E300 Electronic Overload Relay EtherNet/IP Communication Module has
dual Ethernet ports that function as an Ethernet switch with RJ-45 ports to
connect Ethernet cable CAT5 type or better to. 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).
The E300 Electronic Overload Relay EtherNet/IP Communication Module
supports a Star, Linear, and Ring Ethernet topology. An example of a Star
Ethernet Topology is shown below in which all Ethernet nodes wire back to a
central Ethernet switch, hub, or router.
