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.
page 18.
• Bootstrap Protocol (BOOTP)/Dynamic Host Configuration Protocol
(DHCP) server
• RSLinx Classic software
• the Studio 5000 environment
The module uses these tools sequentially to set the IP address.
The 1756 EtherNet/IP communication modules are shipped with
this configuration:
• BOOTP/DHCP enabled
• Rotary switches set to 999 - when applicable
This graphic shows the process used to set your module’s IP address.

This graphic shows the rotary switches on a 1756 EtherNet/IP communication
module. Depending on the module, the switches are on the top or the side of the
module.
Front of
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.

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
Page 20
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.

Grounding Considerations
ATTENTION: This product is grounded through the DIN rail to chassis ground.
Use zinc-plated yellow-chromate steel DIN rail to assure proper grounding. The
use of other DIN rail materials (for example, aluminum or plastic) that can
corrode, oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.87 in.) and use end-anchors appropriately.
Set the Network IP Address
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
You can use these tools to set the network Internet Protocol (IP) address on your
1768 EtherNet/IP communication module:
• Bootstrap Protocol (BOOTP)/Dynamic Host Configuration Protocol
(DHCP) server
ENET-UM001.
• RSLinx Classic software
• the Studio 5000 environemnt
The module uses these tools sequentially to set the IP address.
The 1768 EtherNet/IP communication modules are shipped with BOOTP/
DHCP enabled.

Chapter 2 Install a 1768 EtherNet/IP Communication Module
Set the Network IP Address with a 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.
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 environemnt 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.
3. Type the Subnet Mask of the network.
The Gateway address, Primary and/or Secondary DNS address, and
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.
Install a 1768 EtherNet/IP Communication Module Chapter 2
7. Type an IP Address, Hostname, and Description for the module.
8. Click OK.
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.
Rockwell Automation Publication ENET-IN002F-EN-P - January 2014 41
Page 42
Chapter 2 Install a 1768 EtherNet/IP Communication Module
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 or
RSLogix 5000 software.
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.
• Company policies and procedures dealing with plant floor network
installation and maintenance
RSLinx 43
Studio 5000 environment
(Logix Designer application)
45
• Level of involvement by IT personnel in plant-floor network installation
and maintenance
• Type of training offered to control engineers and maintenance personnel

Page 43
Install a 1768 EtherNet/IP Communication Module Chapter 2
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.

System Configuration
Follow these rules when planning your system configuration.
• The adapter must be the first and left-most module in the system (the first
module of Bank 1). Refer to page
• The adapter can communicate with up to 30 modules in a system
distributed across three I/O banks.
• An end cap/terminator must be on the last I/O bank.
• Each bank of I/O must have its own power supply.
• A bank of I/O can have a maximum of 16 modules with a maximum of
eight on either side of the power supply, depending upon module loading
on the supply.
• A 1769 I/O power supply has limits in the amount of 5V DC and
24V DC current it can supply to the modules in its I/O bank. These limits
depend on the catalog number (for example, 1769-PA2) of the supply. A
bank of modules should not exceed the current limits of the I/O bank
power supply. Refer to the Compact 1769 Expansion I/O Power Supplies
Installation Instructions, publication
• The maximum amount of current the system supports in one direction
(either side of the power supply) is: 2A @ 5V DC, 1A @ 24V DC.
• If another bank of I/O is required due to module requirements or I/O
loading, you can use a cable to link them together. You can have a
maximum of three banks of I/O connected with up to two
communication cables.
• Each module type has its own distance rating (the number of modules
from the power supply). Each module must be within this rating for its
type.
• The adapter has a distance rating of five, therefore the adapter must be
within five modules of the power supply.

At powerup, the adapter 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
• 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.
WARNING: When you change switch settings while power is on, an electrical
arc can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
The module attempts to use the BOOTP/DHCP server to set the IP address if
the rotary switches are not set to a valid number.

Chapter 3 Install a 1769 EtherNet/IP Adapter
Set the Network IP Address with a 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.
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 adapter and uses an address in a format similar to the
following:
00-00-BC-14-55-35
Complete 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.
3. Type the Subnet Mask of the network.
The Gateway address, Primary and/or Secondary DNS address, and
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.
Install a 1769 EtherNet/IP Adapter Chapter 3
7. Type an IP Address, Hostname, and Description for the module.
8. Click OK.
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, when power is cycled, the host
controller clears the current IP configuration and begins sending
BOOTP requests again.

Chapter 3 Install a 1769 EtherNet/IP Adapter
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 adapters, 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 adapter module must be assigned a fixed
network address. The IP address of this module must not be dynamically
provided.
Failure to observe this precaution can result in unintended machine motion or
loss of process control.
Set the Network IP Address with RSLinx or the Studio 5000 Environment
This table describes when to set the network IP address with RSLinx or the
Studio 5000 environment.
Conditions Software to Use Page
• A BOOTP server is not available.
• The EtherNet/IP adapter is connected to another NetLinx network.
The Logix Designer project is online with a controller that communicates to
or through the EtherNet/IP adapter.
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 Logix Designer application or RSLinx software. The BOOTP/DHCP
server also limits the possibility of assigning duplicate IP addresses.
• 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 can get an address
from the enterprise server before the Rockwell Automation utility even sees the
module. In this case, 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.

Fiber Cable and LC Connector
This appendix provides specifications for the fiber cable and LC connector used
with the 1756-EN2F EtherNet/IP fiber module or the 1783-ETAP1F and
1783-ETAP2F EtherNet/IP fiber taps.
Figure 5 - Fiber Cable
Specifications
The 1756-EN2F EtherNet/IP fiber module and the 1783-ETAP1F and
1783-ETAP2F EtherNet/IP fiber taps use a fiber cable and LC connector. The
fiber cable is typically used in 1 m (3 ft), 2 m, (6 ft), 3 m (9 ft), 5 m (15 ft), and
100 m (300 ft) lengths, but supports lengths up to 2 km (1.24 mi).
IMPORTANT
You can special order a fiber cable in any length up to 2 km (1.24 mi) from
your fiber cable vendor.
The fiber cable and LC connector supports these specifications.

EXAMPLE
IMPORTANT
Allow at least 5.08 cm (2 in.) for the fiber cable bend radius. Contact
the cable manufacturer for more information on the recommended cable
bend radius.
In the example shown here, the channel insertion loss is calculated for an optical channel based on these factors:
• 1 dB/km fiber
• 0.75 dB per adapter
Note that in this example, the end connectors are not factored in the calculations.
Fiber 1 dB/km Fiber 1 dB/kmFiber 1 dB/km

Total channel insertion loss = 3.5 db
0.75 dB0.75 dB
ATTENTION: The maximum power budget for this example is 12.8 dB for 62.5/125 m fiber. Therefore, the channel
insertion loss for the example of 3.5 dB is less than the maximum power budget.
