Configure a Supervisor on a Device-level
Ring Network
Introduction
A Device-level Ring (DLR) network is a single-fault tolerant ring network
intended for the interconnection of automation devices.
The ring topology provides:
•media redundancy.
• fast network fault detection and reconfiguration.
• the resiliency of a single-fault tolerant network.
• easy implementation without any additional hardware requirements.
