Ring Topology
In this example, the devices are connected by using ring topology. If only one
device in the ring is disconnected, the rest of the devices continue to
communicate. For ring topology to work correctly, a device level ring (DLR)
supervisor is required (for example, the CompactLogix controller). DLR is an
ODVA standard. For more information, refer to the EtherNet/IP Embedded
Switch Technology Application Guide, publication ENET-AP005
.
Devices without dual ports require a 1783-ETAP module to complete the
network ring.
