Device Level Ring (DLR)
Topology
You can configure a DLR topology on Stratix 5400 switches and some models
of Stratix 5700 and ArmorStratix 5700 switches. For a list of switches that
support a DLR topology, see

Configure DLR via the Logix Designer Application
Overview
A DLR topology is a single-fault-tolerant ring network that is intended for the
interconnection of automation devices without the need for more switches.
The ring topology offers these advantages:
•
Media redundancy
•
Fast-network fault detection and reconfiguration
•
Resiliency of a single-fault-tolerant network
•
Easy implementation without more hardware requirements
One DLR topology can support as many as 50 nodes. A DLR topology
supports copper connections (maximum of 100 m), fiber-optic connections
(maximum of 2 km), or a mix of copper and fiber.
IMPORTANT
To configure DLR, be sure that the switch is using the DLR feature application
profile as described on
IMPORTANT
This section summarizes a DLR topology. To plan, configure, and monitor
DLR topologies, see EtherNet/IP Embedded Switch Technology Application
