Preface
Purpose of this Manual
This manual guides the development of projects for ControlLogix
controllers. It provides step-by-step procedures on how to establish
communications:
•over the following networks
–EtherNet/IP
–ControlNet™
–remote I/O
–DH+™
–DH-485
–serial
•with the following devices
–controllers
–I/O
–workstations
–PanelView™terminals
This manual works together with the Logix5000 Controllers Common
Procedures, publication 1756-PM001, which covers the following
tasks:
•Manage project files
•Organize your logic
•Organize tags
•Program routines
•Test a project
•Handle faults
Who Should Use this
Manual
This manual is intended for those individuals who program
applications that use ControlLogix controllers, such as:
•software engineers
•control engineers
•application engineers
•instrumentation technicians

Preface 2
When to Use this Manual
Use this manual:
•when you are ready to integrate your application with the I/0
devices, controllers, and networks in your system.
•after you perform these actions:
–develop the basic code for your application
–perform isolated tests of your application
How to Use this Manual
This manual is divided into the basic tasks that you perform while
programming a ControlLogix controller.
•Each chapter covers a task.
•The tasks are organized in the sequence that you will typically
perform them.
As you use this manual, you will see some terms that are formatted
differently from the rest of the text:
Text that is: Identifies: For example: Means:
Italic the actual name of an item that you
see on your screen or in an example
Right-click User-Defined … Right-click on the item that is named
User-Defined.
courier information that you must supply
based on your application (a
variable)
Right-click
name_of_program …
You must identify the specific program in
your application. Typically, it is a name or
variable that you have defined.

Configure an EtherNet/IP Module
When to Use This
Procedure
Use this procedure to configure any of the following modules:
You can configure a module either:
•before you install the module
–Configure the module in a temporary location, such as a
chassis that is on a test bench.
–After you configure the module, install it in your system.
•after you install the module in your system

1-2 Configure an EtherNet/IP Module
Before You Begin
The configuration of an EtherNet/IP module includes:
•IP address (required)
•subnet mask (recommended)
•gateway address (optional)
•domain name (optional)
•DNS server addresses (optional)
You use software to configure an EtherNet/IP module. (The modules
do not have hardware switches to assign an address.) To configure a
module, use one of these software:
•RSLogix 5000 Software
•RSLinx Software
•BOOTP Server Software
To determine which software lets you configure your module, use the
following table:
To configure this module: Use one of these software:
RSLogix 5000 RSLinx BOOTP server

1756-ENET ✔✔✔
1794-AENx ✔

Configure an EtherNet/IP Module 1-3
RSLogix 5000 Software
RSLogix 5000 software lets you configure a 1756-ENBx or -ENET
module via another module that is in the chassis.
Use RSLogix 5000 software to assign:
•IP address (required)
•subnet mask (recommended)
•gateway address (optional)
•domain name (optional)
•DNS server addresses (optional)
When you configure a module with RSLogix 5000 software, you enter
an IP address or host name in two locations:

RSLinx Software
RSLinx software lets you configure a 1756-ENBx or -ENET module via
another module in the chassis.
Use RSLinx software to assign:
•IP address (required)
•subnet mask (recommended)
•gateway address (optional)
•domain name (optional)
•DNS server addresses (optional)
