Each Ethernet port has two indicators that provide the activity status.
Device Level Ring Network Topology
A Device Level Ring (DLR) network is a single-fault tolerant ring network that is
intended for the interconnection of automation devices. This topology is also
implemented at the device level. No additional switches are required.
When a fault occurs, the fault location is determined and the supervisor
reconfigures the network to continue sending data on the network. Once the
fault is corrected, the supervisor reconfigures the network to operate as a normal
ring (versus a faulted ring).
For more information on DLR network topology, see EtherNet/IP Embedded
Switch Technology Application Guide, publication
ENET-AP005 .
