Install the CompactLogix 5370 L2 Controller
Connect the Controller to an
EtherNet/IP Network
Connect the RJ45 connector of the Ethernet cable to one of the Ethernet ports
on the controller. The ports are on the bottom of the controller.
Connecting to Different EtherNet/IP Network Topologies
CompactLogix 5370 L2 controllers have embedded switch technology and two
EtherNet/IP ports that let you use it in various EtherNet/IP network topologies:
•
Device-level ring network topology - Both ports on the controller are
connected to the network.
•
Linear network topology - Both ports on the controller are connected to
the network.
•
Star network topology - One port on the controller is connected to
the network.
There are connection and configuration requirements for each EtherNet/IP
network topology.
For more information, see
EtherNet/IP Network Topologies on page 127
WARNING:
If you connect or disconnect the communication cable with
power applied to this module or any device on the network, an electrical arc
can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
ATTENTION:
Do not plug a DH-485 network cable or a NAP cable into the
Ethernet port. Undesirable behavior and/or damage to the port can result.
IMPORTANT
This example shows how to connect the controller to the network through one
port. Depending on the network topology of your application, you can connect
both ports of the controller to the EtherNet/IP network.
