Install a 1769 EtherNet/IP Adapter Chapter 3
Use the Module in a Device-level Ring (DLR) Network
The module is configured by default to be used in a linear or star topology, or as a
ring node in a DLR network. Follow these steps to use the module in a DLR
network as a ring supervisor.
1. If you are using the unit as a ring supervisor, follow the procedures
outlined in the online help that accompanies RSLinx or the Logix
Designer application to enable the ring supervisor function with this
software.
2. Refer to the EtherNet/IP Embedded Switch Technology Application
Guide, publication
nformation on setting up
EtherNet/IP network topologies.
IMPORTANT
• Make sure at least one ring supervisor is present before
connecting the last link of a device-level ring network and
physically closing the ring.
• Do not connect nodes that do not support a device-level
ring as members of the ring.
