Configure a Supervisor on a Device-level Ring Network Chapter 5
Example Device-level Ring Topology
Supervisor Node
A DLR network requires at least one node to be configured as ring supervisor.
Currently, two Rockwell Automation products support the ring supervisor
functionality.

Out of the box, the supervisor-capable devices have their
supervisor function disabled so they are ready to participate in
either a linear/star network topology, or as a ring node on an
existing DLR network.
In a DLR network, you must configure at least one of the
supervisor-capable devices as the ring supervisor before
physically connecting the ring. If not, the DLR network will
not work.
