Chapter 3 Install the CompactLogix 5370 L3 Controller
Connecting to Different EtherNet/IP Network Topologies
The CompactLogix 5370 L3 controllers have embedded switch technology and
two EtherNet/IP ports that let you use it in different EtherNet/IP
network topologies:
• Device-level Ring network topology - Both ports on the controller are
connected to the network with requirements about how the connections
are made.
• Linear network topology - Both ports on the controller are connected to
the network with requirements about how the connections are made.
• Star network topology - One port on the controller is connected to
the network.
