Ethernet Ports
There are two Ethernet ports on the module.
Port 2
The FactoryTalk® Optix™ RA EtherNet/IP driver only supports Port 2. Only Port 2 can be used
for EtherNet/IP communication. This Ethernet port can communicate on an EtherNet/IP
network at a maximum network communication speed of 1 Gbps.
You can configure this port either with the Module Properties dialog in the Studio 5000 Logix
Designer application, or with System Manager.
• To configure with the Module Properties Dialog, see Internet Protocol on page 21
.
• To configure with System Manager, see Interfaces on page 33
.
Port 1
Port 1 can support enterprise-wide Ethernet communication. This Ethernet port can
communicate on an Ethernet network at a maximum network communication speed of 1 Gbps.
You can only configure this port with System Manger. See Interfaces on page 33
.
Considerations
• You can use any IP address and mask values in your application.
• You can configure the IP address and mask to be static or dynamic.
- If an IP address and mask are static, they remain assigned to the port after power is
cycled to the module.
- If an IP address and mask are dynamic, they are cleared from the port each time
power is cycled to the module. A DHCP server must reassign values. Remember, the
IP address and mask values that are assigned after a power cycle can differ from the
ones that were used before a power cycle.
We recommend that you set the IP addresses to be static.

WARNING: If you connect or disconnect an Ethernet cable with power applied to
this module or any device on the network, an electric arc can occur. This can
cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
