Chapter 1
EtherNet/IP Overview
EtherNet/IP networks are communication networks that offer a comprehensive
suite of messages and services for many automation applications.
These are examples of applications that use EtherNet/IP networks:
• Real Time Control
• Time Synchronization
• Motion
This open network standard uses off-the-shelf Ethernet communication products
to support real-time I/O messaging, information exchange, and general
messaging.
EtherNet/IP Communication Modules in a Control System
EtherNet/IP networks also support CIP Safety, making the simultaneous
transmission of safety and standard control data and diagnostics information over
a common network possible.
Depending on the type, Rockwell Automation EtherNet/IP communication
modules provide some of this functionality:
• Support for messaging, produced/consumed tags, and distributed I/O
• Encapsulate messages within standard TCP/UDP/IP protocol
• Share a common application layer with ControlNet and DeviceNet
network protocols
• Interface via RJ45, category 5, unshielded, twisted-pair cable connectors
• Fiber connectors
• Support for half/full duplex 10 Mbps or 100 Mbps operation
• No network scheduling or routing table requirements

network.
For more information on DNS addressing, see
page 31.
Check with your Ethernet network administrator to determine if you need to
specify these parameters.
Set the Network IP Address on a Module
Depending on the EtherNet/IP communication module, you can use some or all
of these tools to set the network Internet Protocol (IP) address:
• Rotary switches - Switches are physical parts on the module. Remember
the following as you read this chapter:
– Some EtherNet/IP communication modules use thumbwheel switches.
that function similarly to rotary switches. This chapter uses the term
rotary switches to describe both switch types.
– Some EtherNet/IP communication modules do not have rotary
switches. If your module does not have switches, skip Set the Network

page 20 and go to Set the
page 21.
– 1783-ETAPx EtherNet/IP taps use DIP switches to set the network IP
address. For more information on how to use the DIP switches, see the
publications for those products.
• Bootstrap Protocol (BOOTP)/Dynamic Host Configuration Protocol
(DHCP) server
• RSLinx Classic software
• Studio 5000 environment
The module uses these tools sequentially to set the IP address.

Chapter 3 Configure an EtherNet/IP Communication Module to Operate on the Network
Set the Network IP Address with the Rotary Switches
This graphic shows the rotary switches on a 1756 EtherNet/IP communication
module. The location of the switches is dependant on the module.
At powerup, the module reads the rotary switches to determine if they are set to a
valid number for the last portion of the IP address. Valid numbers range from
001…254.
If the settings are a valid number, these conditions result:
• IP address = 192.168.1.xxx (where xxx represents the switch settings)
• Subnet mask = 255.255.255.0
• Gateway address = 0.0.0.0
TIP
Some modules now provide a gateway address of 192.168.1.1 when the
network address is set with rotary switches. Refer to the product
documentation to determine the correct gateway address the module uses.
• The module does not have a host name assigned, nor does it use any
Domain Name System
We recommend that you set the rotary switches to a valid number before
installing the module.
If either of these conditions exist, the module attempts to use the BOOTP/
DHCP server to set the IP address:
• Rotary switches are not set to a valid number
• Module does not have rotary switches
For more information on using the BOOTP/DHCP server to set the IP address,

Configure an EtherNet/IP Communication Module to Operate on the Network Chapter 3
Set the Network IP Address with the BOOTP/DHCP Server
The BOOTP/DHCP server is a standalone server you can use to set an IP
address. When used, the BOOTP/DHCP server sets an IP address and other
Transport Control Protocol (TCP) parameters.
You can use the BOOTP/DHCP server to set the module’s IP address if one of
these conditions exists at powerup:
• The module’s rotary switches are not set to a number and the module is
BOOTP/DHCP enabled.
• The module does not have rotary switches and the module is BOOTP/
DHCP enabled.
Access the BOOTP/DHCP server from one of these locations:
• Programs > Rockwell Software > BOOTP-DHCP Server
If you have not installed the server, you can download and install it from
http://www.ab.com/networks/ethernet/bootp.html.
• Tools directory on the Studio 5000 environment installation CD
IMPORTANT
Before you start the BOOTP/DHCP server, make sure you have the
module’s hardware (MAC) address. The hardware address is on a sticker
on the side of the communication module and uses an address in a
format similar to the following:
00-00-BC-14-55-35
To set the module’s IP address with a BOOTP/DHCP server, follow these steps.
1. Start the BOOTP/DHCP software.
2. From the Tools menu, choose Network Settings.

9. To permanently assign this configuration to the module, wait for the
module to appear in the Relation List panel and select it.
10. Click Disable BOOTP/DHCP.
When power is recycled, the module uses the assigned configuration and
does not issue a BOOTP request.
IMPORTANT
If you do not click Disable BOOTP/DHCP, on a power cycle, the host
controller clears the current IP configuration and begins sending
BOOTP requests again.
Use DHCP Software
Dynamic Host Configuration Protocol (DHCP) software automatically assigns
IP addresses to client stations logging onto a TCP/IP network. DHCP is based
on BOOTP and maintains some backward compatibility. The main difference is
that BOOTP allows for manual configuration (static), while DHCP allows for
both static and dynamic allocation of network addresses and configurations to
newly attached modules.
Be cautious when using DHCP software to configure a module. A BOOTP
client, such as the EtherNet/IP communication modules, can start from a DHCP
server only if the DHCP server is specifically written to also handle BOOTP
queries. This is specific to the DHCP software package used. Consult your
system administrator to see if a DHCP package supports BOOTP commands
and manual IP allocation.
ATTENTION: The EtherNet/IP communication module must be assigned a
fixed network address. The IP address of this module must not be dynamically
provided.
Failure to observe this precaution may result in unintended machine motion or
loss of process control.

Chapter 3 Configure an EtherNet/IP Communication Module to Operate on the Network
Set the Network IP Address with RSLinx Software or the Studio 5000 Environment
This table describes when to set the network IP address with RSLinx software or
the Studio 5000 environment.
Conditions Software to Use Page
• A BOOTP server is not available
• The EtherNet/IP communication module is connected to another NetLinx
network
The Studio 5000 Logix Designer project is online with a controller that
communicates to or through the EtherNet/IP communication module
Consider these factors when you determine how to set the network IP address:
• Network isolation from or integration into the plant/enterprise network
• Network size - For large networks, isolated networks, it might be more
convenient and safer to use a BOOTP/DHCP server rather than the
Studio 5000 Environment or RSLinx software. The BOOTP/DHCP
server also limits the possibility of assigning duplicate IP addresses.
RSLinx software 25
Studio 5000 environment 28
• Company policies and procedures dealing with plant floor network
installation and maintenance
• Level of involvement by IT personnel in plant-floor network installation
and maintenance
• Type of training offered to control engineers and maintenance personnel
If you use the Rockwell Automation BOOTP or DHCP server in an uplinked
subnet where an enterprise DHCP server exists, a module may get an address
from the enterprise server before the Rockwell Automation utility even sees the
module. You might have to disconnect from the uplink to set the address and
configure the module to retain its static address before reconnecting to
the uplink. This is not a problem if you have node names configured in the
module and leave DHCP enabled.

following methods:
• If the module has rotary switches, set the switches to 888 and cycle power.
• If the module does not have rotary switches, use a MSG instruction to the
reset the IP address.
Duplicate IP Address Detection
Some EtherNet/IP communication modules support duplicate IP
address detection. The module verifies that its IP address does not match any
other network device’s IP address when you perform either of these tasks:
• Connect the module to a EtherNet/IP network.
• Change the module’s IP address.
If the module’s IP address matches that of another device on the network, the
module’s EtherNet/IP port transitions to Conflict mode. In Conflict mode, these
conditions exist:
• OK status indicator is blinking red.
• Network (NET) status indicator is solid red.
• On some EtherNet/IP communication modules, the module status display
indicates the conflict.
The display scrolls:OK <IP_address_of_this_module> Duplicate IP
<Mac_address_of_duplicate_node_detected>
For example: OK 10.88.60.196 Duplicate IP - 00:00:BC:02:34:B4
• On some EtherNet/IP communication modules, the module’s diagnostic
webpage displays information about duplicate IP address detection.
For more information on which EtherNet/IP communication modules
support displaying duplicate IP address on their diagnostic webpage, see

Duplicate IP Address Resolution
When two EtherNet/IP communication modules on a network have conflicting
IP addresses, the resolution depends on the conditions in which the duplication is
detected. This table describes how duplicate IP addresses are resolved.
Duplicate IP Address Detection Conditions Resolution Process
• Both modules support duplicate IP address detection
• Second module is added to the network after the first
module is operating on the network
• Both modules support duplicate IP address detection
• Both modules were powered up at approximately the same
time
One module supports duplicate IP address detection and a
second module does not
1. The module that began operation first uses the IP address and continues to operate without interruption.
2. The module that begins operation second detects the duplication and enters Conflict mode.
To assign a new IP address to the module and leave Conflict mode, see
on page 18.
Both EtherNet/IP devices enter Conflict mode.
To resolve this conflict, follow these steps:
a. Assign a new IP address to one of the modules by using the methods described in
Address on a Module on page 18.
b. Cycle power to the other module.
1. Regardless of which module obtained the IP address first, the second module, that is, the module that does not
support IP address detection, uses the IP address and continues to operate without interruption.
2. The module that supports duplicate IP address detection detects the duplication and enters Conflict mode.
To assign a new IP address to the module and leave Conflict mode, see
on page 18.

IP Address Swapping
Devices experiencing duplicate IP address conditions behave differently
depending on whether connections have been established to either of the
modules and whether both modules support duplicate IP address detection.
Some EtherNet/IP communication modules support IP address swapping. This
functionality is used in ControlLogix enhanced redundancy systems. During a
system switchover, partnered EtherNet/IP communication modules swap IP
addresses.
For more information about IP address swapping, see the ControlLogix
Enhanced Redundancy System User Manual, publication
1756-UM535.
