Configure the EtherNet/IP Network Chapter 3
What You Need
Tab le 6 lists the software components you use in this chapter.
Assign an IP Address to the Controller Over a USB Connection
At initial powerup, the CompactLogix 5370 L3 controller does not have an IP address. Use
RSLinx Classic software over a USB connection to assign an IP address. If the computer with
RSLinx Classic software is not connected to the controller via a USB connection, the following
steps will not work.
1. Verify that your computer is connected to the USB port on the front of the controller.
Table 6 - What You Need to Configure the EtherNet/IP Network
Component Description
Studio 5000 environment Environment that combines engineering and design elements into a common environment.
Logix Designer application Application used to create a project the CompactLogix 5370 L3 controller uses in your application.
RSLinx Classic software Communication server that supports multiple software applications simultaneously, establishing
communicating between devices on many different Rockwell Automation industrial networks.
IP address A number in the form xxx.xxx.xxx.xxx where each xxx is a number from 000…254.
The IP address uniquely identifies the controller on the EtherNet/IP network.
Subnet mask Extension of the IP address that allows a site to use a single network ID for multiple
physical networks.
If you change the subnet mask of a configured controller, you must cycle power to the controller
for the change to take effect.
There are other methods to assign an IP address to the controller, such as using the BOOTP/DHCP utility. This section is
only one example of how to assign the IP address to the controller.
For more information on the methods of assign an IP address to the CompactLogix 5370 L3 controller, see the
CompactLogix 5370 Controllers User Manual, publication 1769-UM021
