Rockwell Automation Publication ENET-IN002H-EN-P - August 2017 7
Preface
This manual describes how to install and start up EtherNet/IP module systems
with Logix5000™controllers.
Use this manual if you program applications that use an EtherNet/IP network
with one of these Logix5000 controllers:
•CompactLogix™
•ControlLogix®
Understand the following:
•Networking concepts
•How to the use Studio 5000™environment
•How to use RSLinx®Classic programming software
Download the Add-on
Profiles and Firmware
If a communication module has a later firmware revision than recognized in the
current version of the Logix Designer™ application, you must download the latest
firmware. When you download the Add-on Profile (AOP) for the module, it can
be recognized in the Controller Organizer.
Download the Add-on Profile and the latest module firmware from the Product
Compatibility and Download website at http://www.ab.com.
If the procedure is performed while the web pages are already enabled, they
continue to be enabled and the password is reset to the serial number of the
adapter.
