Set the Network IP Address on a Module
To operate an EtherNet/IP communication module on an EtherNet/IP network,
you must set a network IP address.
The IP address uniquely identifies the module. The IP address is in the form
xxx.xxx.xxx.xxx where each xxx is a number from 000…254.
There are some reserved values that you cannot use as the first octet in the
address. These numbers are examples of values you cannot use:
• 001.xxx.xxx.xxx
• 127.xxx.xxx.xxx
• 223 to 255.xxx.xxx.xxx
The specific reserved values that cannot be used vary by application.
For more information about configuring an EtherNet/IP network, see
EtherNet/IP Network Configuration User Manual, publication
Depending on the 1756 EtherNet/IP communication module, you can use some
or all of these tools to set the network Internet Protocol (IP) address:
• Rotary switches - The 1756-ENBT and 1756-EWEB modules do not offer
rotary switches. If you are using either of these modules, skip Set the
Network IP Address with the Rotary Switches on
the Network IP Address with the BOOTP/DHCP Server on
page 17 and go to Set
ENET-UM001.

Module
Rotary Switches
32454
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, that is, if the numbers are in
the 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
= 192.168.1.1 for firmware revision 5.008 or later
= 0.0.0.0 for firmware revision 5.007 or earlier
IMPORTANT
The gateway address of 192.168.1.1 applies only to the 1756-EN2T,
1756-EN2TR, 1756-EN2TRXT, 1756-EN2F, 1756-EN2TSC, and
1756-EN3TR modules with firmware revision 5.008 or later. Other
modules use the gateway address of 0.0.0.0 with firmware revision
5.007 or earlier.
For more information, see the Ethernet Design Considerations
Reference Manual, publication
ENET-RM002.
• 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.
Rockwell Automation Publication ENET-IN002F-EN-P - January 2014 17
Chapter 1 Install a 1756 EtherNet/IP Communication Module
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:
Access the BOOTP/DHCP server from one of these locations:
• The module’s rotary switches are not set to a valid number and the module
is BOOTP/DHCP enabled.
• The module does not have rotary switches and the module is
BOOTP/DHCP enabled.
• 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
Follow these steps to set the module’s IP address with a BOOTP/DHCP server.
1. Start the BOOTP/DHCP software.
2. From the Tools menu, choose Network Settings.

Domain Name fields are optional.
4. Click OK.
The Request History panel appears with the hardware addresses of all
modules issuing BOOTP requests.
5. Select the appropriate module.
6. Click Add to Relation List.
The New Entry dialog box appears.
7. Type an IP Address, Hostname, and Description for the module.
8. Click OK.
Rockwell Automation Publication ENET-IN002F-EN-P - January 2014 19
Chapter 1 Install a 1756 EtherNet/IP Communication Module
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.

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 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 22
Studio 5000 environment 24
• 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.
