EtherNet/IP Communications
Introduction
This chapter provides 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 RJ45 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. Figure 49
shows an example
of a Star Ethernet Topology, in which all Ethernet nodes wire back to a central
Ethernet switch, hub, or router.
