Chapter 2 Install the PanelView Plus 7 Standard Terminal
Only PanelView Plus 7 standard terminals with two Ethernet ports, for
example, catalog number 2711P-T10C22D8S, operate on a DLR network.
DLR network topologies automatically convert to linear network topologies
when a fault is detected. The conversion to the new network topology
maintains communication of data on the network. The fault condition is
typically detected and corrected.
For more information on DLR network topology, refer to EtherNet/IP
Embedded Switch Technology Application Guide, publication ENET-AP005
.

Linear Network Topology
A linear network topology is a collection of devices that are daisy-chained
together across an EtherNet/IP network. Devices that can connect to a linear
network topology use embedded switch technology to eliminate the need for a
separate switch, as required in Star network topologies.
