EtherNet/IP Features in Allen-Bradley Network
Devices
EtherNet/IP networks offer a comprehensive suite of messages and services for
many automation applications. This open network standard uses standard
Ethernet communication products to support real-time I/O messaging,
information exchange, and general messaging. Other features to all EtherNet/
IP network devices include the following:
• Support for messaging, produced/consumed tags, and distributed I/O
• DNS addressing
• Internet Group Management Protocol (IGMP) snooping (enabled by
default) and querier (disabled by default)
• Port configuration and diagnostics
•Emailserver
EtherNet/IP networks also support CIP Safety applications. Such support
makes the simultaneous transmission of safety and standard control data and
diagnostics information over a common network possible.

Duplicate IP Address
Detection
Duplicate IP address detection verifies that an IP address does not match any
other device IP address on the network when you perform either of these tasks:
• Connect the device to a EtherNet/IP network.
• Change the IP address on the device.
If the IP address matches that of another device on the network, the
EtherNet/IP port on the device transitions to conflict mode. In conflict mode,
these conditions exist:
• OK status indicator blinks red.
• Network (NET) status indicator is solid red.
• If the device has a text display, the following message scrolls across the 4-
character display:
<IP_address_of_this_device> Duplicate IP -
<MAC_address_of_duplicate_node_detected>
For example: 10.88.60.196 Duplicate IP - 00:00:BC:02:34:B4
Duplicate IP Address Resolution
This table describes how to resolve duplicate IP addresses.
Duplicate IP Address Detection Conditions Resolution Process
• Both devices support duplicate IP address detection
• Second device is added to the network after the first
device is operating on the network
1. The device that began operation first uses the IP address and continues to operate without interruption.
2. The device that begins operation second detects the duplication and enters Conflict mode.
• Both devices support duplicate IP address detection
• Both devices were powered up at approximately the
same time
Both EtherNet/IP devices enter Conflict mode.
To resolve this conflict, follow these steps:
a. Assign a new IP address to one of the devices.
b. Cycle power to the other device or disconnect and reconnect all Ethernet cables from the other device.
One device supports duplicate IP address detection and a
second device does not
1. Regardless of which device obtained the IP address first, the device that does not support IP address detection
uses the IP address and continues to operate without interruption.
2. The device that supports duplicate IP address detection detects the duplication and enters Conflict mode.
