Chapter 1
EtherNet/IP Overview
EtherNet/IP Communication
Modules in a Control System
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 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

Chapter 2
Configure a Workstation to Operate on an EtherNet/IP Network
This chapter describes how to configure a workstation to operate on an
EtherNet/IP network.
You must configure an Ethernet communication driver in RSLinx software for the workstation.
A workstation needs the driver to perform these tasks:
•Upload and download Studio 5000 environment project information to controllers over an EtherNet/IP network.
•Configure EtherNet/IP network parameters for devices via RSNetWorx for EtherNet/IP software.
•Collect controller data for electronic operator interfaces, for example,
PanelView Plus terminals, and visualization software, for example,
FactoryTalk View software.
You can choose either of these Ethernet drivers:
•AB_ETHIP
•AB_ETH
Before you add a new driver, confirm these conditions exist:
•Workstation is properly connected to the EtherNet/IP network
•IP address and other network parameters are correctly configured for the workstation

Determine Network
Parameters
To operate an EtherNet/IP network, you must define these parameters.
EtherNet/IP Network Parameter |
Description |
|
|
|
|
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 according the conditions of each application. The previous values |
|
|
are only examples of reserved values. |
|
|
|
|
Subnet mask |
Subnet addressing is an extension of the IP address scheme that allows a site to use a single network ID for multiple |
|
|
physical networks. Routing outside of the site continues by dividing the IP address into a net ID and a host ID via the |
|
|
class. Inside a site, the subnet mask is used to redivide the IP address into a custom network ID portion and host ID |
|
|
portion. This field is set to 0.0.0.0 by default. |
|
|
If you change the subnet mask of an already-configured module, you must cycle power to the module for the change |
|
|
to take effect. |
|
|
|
|
Gateway |
A gateway connects individual physical networks into a system of networks. When a node needs to communicate with |
|
|
a node on another network, a gateway transfers the data between the two networks. This field is set to 0.0.0.0 by |
|
|
default. |
|
|
|

Chapter 3 Configure an EtherNet/IP Communication Module to Operate on the Network
|
If you use DNS addressing, or reference the module via host name in MSG |
|
|
instructions, define these parameters. |
|
Table 1 - EtherNet/IP Network Parameters for DNS Addressing |
||
|
|
|
EtherNet/IP Network Parameter |
Description |
|
|
|
|
Host name |
A host name is part of a text address that identifies the host for a module. The full text address of a module is |
|
|
host_name.domain_name. |
|
|
|
|
Domain name |
A domain name is part of a text address that identifies the domain in which the module resides. The full text address of a module is |
|
|
host_name.domain_name. The domain name has a 48-character limit. |
|
|
If you specify a DNS server, you must type a domain name. Also, if you send email from the module, some mail relay servers require a |
|
|
domain name during the initial handshake of the SMTP session. |
|
|
|
|
Primary DNS server address |
This identifies any DNS servers used in the network. You must have a DNS server configured if you specified a domain name or a host |
|
|
name in the module’s configuration. The DNS server converts the domain name or host name to an IP address that can be used by the |
|
Secondary DNS server address |
||
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
IP Address with the Rotary Switches on page 20 and go to Set the
Network IP Address with the BOOTP/DHCP Server on 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, see page 21.

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.

Chapter 3 |
|
|
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 |
RSLinx software |
25 |
• The EtherNet/IP communication module is connected to another NetLinx |
|
|
network |
|
|
|
|
|
The Studio 5000 Logix Designer project is online with a controller that |
Studio 5000 environment |
28 |
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
•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.

Duplicate IP Address
Detection
Reset the Module IP Address to Factory Default Value
You can reset the module’s IP address to its factory default value with the 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.
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 the Technical Note titled Logix modules Duplicate IP address detection enhancement, #118216, in the Technical Support Knowledgebase available at http://www.rockwellautomation.com/knowledgebase/.

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 |
1. |
The module that began operation first uses the IP address and continues to operate without interruption. |
• Second module is added to the network after the first |
2. |
The module that begins operation second detects the duplication and enters Conflict mode. |
|
|
|
module is operating on the network |
|
To assign a new IP address to the module and leave Conflict mode, see Set the Network IP Address on a Module |
|
|
on page 18. |
|
|
|
• Both modules support duplicate IP address detection |
Both EtherNet/IP devices enter Conflict mode. |
|
• Both modules were powered up at approximately the same |
To resolve this conflict, follow these steps: |
|
time |
|
a. Assign a new IP address to one of the modules by using the methods described in Set the Network IP |
|
|
Address on a Module on page 18. |
|
|
b. Cycle power to the other module. |
|
|
|
One module supports duplicate IP address detection and a |
1. |
Regardless of which module obtained the IP address first, the second module, that is, the module that does not |
second module 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 Set the Network IP Address on a Module |
|
|
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.
