Ring Topology
For a Kinetix 5700 servo system in 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, see 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.
