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 Bulletin 1783 ETAP device). 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, for example the display terminal, require a
1783-ETAP module to complete the network ring.
