Chapter 8 EtherNet/IP Network
Star Network Topology
A star network topology is a traditional EtherNet/IP network that includes multiple devices that
are connected to each other through an Ethernet switch.

Nodes on an EtherNet/IP
Network
Micro850 (2080-L50E) and Micro870 (2080-L70E) controllers with firmware revision 21.011 or
later support Implicit messaging to EtherNet/IP devices in either a generic tag or as a
predefined tag in Connected Components Workbench software version 21 or later. PowerFlex®
520-series drives and Kinetix® 5100 motion drives are supported with predefined tags. Other
EtherNet/IP devices are supported with generic profile tags. These controllers support up to
eight EtherNet/IP devices in the module configuration section of the project.
