Install the CompactLogix 5370 L3 Controller Chapter 3
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.
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 or damage to the port can result.
This example shows how to connect the controller to the network through one
port. Depending on the Ethernet network topology of your application, you can
connect both ports of the controller to the EtherNet/IP network.
For more information on EtherNet/IP network topologies, see page 127
