The E300 Electronic Overload Relay EtherNet/IP Communication Module also
supports an EtherNet Ring topology in which all Ethernet nodes are wired in
series with one another until a complete network ring is made as shown below.
The E300 Electronic Overload Relay EtherNet/IP Communication Module
supports Rockwell Automation's Device Level Ring (DLR) topology as a slave
device in which the EtherNet/IP network will still continue to communicate in
the event that one of the network chains is disrupted
