CompactLogix 5480 controllers support these EtherNet/IP network types:
•
DLR Network Topology
•
Linear Network Topology
•
Star Network Topology
DLR Network Topology
A DLR network topology is a single-fault tolerant ring network that is
intended for the interconnection of automation devices. A DLR network uses
Supervisor (Active and Backup) nodes and Ring nodes.
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 easily detected and corrected.
The controller is typically in Linear/DLR mode when it is used in a DLR
topology. If the controller operates in Dual-IP mode, it must connect to a DLR
topology via a 1783-ETAP that is connected to an Ethernet port on
the controller.
