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 the 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.
