Chapter 1 EtherNet/IP Features in Allen-Bradley Network Devices
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.

Rockwell Automation Publication ENET-UM006A-EN-P - March 2019 11
EtherNet/IP Features in Allen-Bradley Network Devices Chapter 1
DNS Addressing To qualify the device address further, use DNS addressing to specify a host
name for a device. When you specify a host name for the device, you also
specify a domain name and DNS servers. DNS addressing makes it possible to
create similar network structures and IP address sequences under different
domains.
DNS addressing is necessary only if you refer to the device by host name, such
as in path descriptions in MSG instructions.
To use DNS addressing, follow these steps.
1. Assign a host name to the device.
A network administrator can assign a host name. Valid host names must
be IEC-1131-3 compliant.
2. Configure the device IP address:
In the DNS server, the host name must match the IP address of
the device.
IMPORTANT Make sure the DNS enable bit is set.
• If you use Logix Designer application, version 28 or later, to configure
your device, the enable bit is set and DNS addressing is successful.
• If you use RSLinx® Classic software, version 2.41.00 or later, to
configure your device, the enable bit is cleared and DNS addressing
fails.

12 Rockwell Automation Publication ENET-UM006A-EN-P - March 2019
Chapter 1 EtherNet/IP Features in Allen-Bradley Network Devices
3. In the Logix Designer application, add the device to the I/O.
Socket Interface Some EtherNet/IP devices support the use of a CIP Generic MSG instruction
to request socket services. For more information, see EtherNet/IP Socket
Interface Application Technique, ENET-AT002.
Linear Network A linear network is a collection of devices that are daisy-chained together. The
EtherNet/IP embedded switch technology lets you implement this topology at
the device level. No additional switches are required.
Figure 2 - Example Linear Network
The following are advantages of a linear network.
• Simple installation
• Reduced wiring and installation costs
• No special software configuration required
• Improved CIP Sync application performance on linear networks
The primary disadvantage of a linear network is that any break of the cable
disconnects all devices downstream from the break from the rest of the
network.
IMPORTANT If a child device resides in the same domain as its parent device, type the
host name. If the domain name of the child device differs from its parent
device, type the host name and the domain name (host.domain)
IMPORTANT You can also use DNS addressing in a device profile in the I/O
configuration tree or in a message path. If the domain name of the
destination device differs from the source device, use a fully qualified
DNS name (hostname.domainname). For example, to send a message
from AEN2TR1.location1.companyA to AEN2TR1.location2.company, the
host names match, but the domains differ.Without the entry of a fully
qualified DNS name, the device adds the default domain name to the
specified host name.

EtherNet/IP Features in Allen-Bradley Network Devices Chapter 1
Device Level Ring Device Level Ring (DLR) is an EtherNet/IP protocol that is defined by the
Open DeviceNet® Vendors’ Association (ODVA). DLR provides a means to
detect, manage, and recover from single faults in a ring-based network.
A DLR network includes the following types of ring nodes.
Depending on their firmware capabilities, both devices and switches can
operate as supervisors or ring nodes on a DLR network. Only switches can
operate as redundant gateways.
For more information about DLR, see the EtherNet/IP Device Level Ring
Application Technique, publication ENET-AT007.
Node Description
Ring supervisor A ring supervisor provides these functions:
• Manages traffic on the DLR network
• Collects diagnostic information for the network
A DLR network requires at least one node to be configured as ring supervisor.
IMPORTANT: By default, the supervisor function is disabled on supervisor-capable
devices, so they are ready to participate on a linear or star network or as a ring node on a
DLR network.
In a DLR network, you must configure at least one of the supervisor-capable devices as
the ring supervisor before physically connecting the ring. If you do not, the DLR network
does not work.
Ring participants Ring participants provide these functions:
• Process data that is transmitted over the network.
• Pass on the data to the next node on the network.
• Report fault locations to the active ring supervisor.
When a fault occurs on the DLR network, ring participants reconfigure themselves and
relearn the network topology.
Redundant gateways
(optional)
Redundant gateways are multiple switches that are connected to one DLR network and
also connected together through the rest of the network.
Redundant gateways provide DLR network resiliency to the rest of the network.

Parallel Redundancy
Protocol
Parallel Redundancy Protocol (PRP) is defined in international standard
IEC 62439-3 and provides high-availability in Ethernet networks. PRP
technology creates seamless redundancy by sending duplicate frames to two
independent network infrastructures, which are known as LAN A and LAN B.
A PRP network includes the following components.
For more information about PRP topologies and configuration guidelines, see
the EtherNet/IP Parallel Redundancy Protocol Application Technique,
publication ENET-AT006.

Reserve 10% of the bandwidth (packets/second) of the network device for
Explicit Messaging.
Time Synchronization In certain situations, the I/O modules can synchronize with the adapter before
the adapter synchronizes with the system Grandmaster clock. This
synchronization occurrence leads to a time difference between the I/O and the
Grandmaster clock until the adapter synchronizes with the Grandmaster clock.
In your logic, verify that the adapter is synchronized with the Grandmaster
clock (CIPSyncValid) before you initiate time stamp requests or scheduled
outputs from your I/O modules. A system with intermediate devices, such as
network bridges and switches, can require that you insert a delay until the time
stabilizes in the system.
For information on how to verify that the adapter is synchronized to a
Grandmaster clock, see CIP Sync Diagnostics in the Integrated Architecture
and CIP Sync Configuration Application Technique, publication IA-AT003.
This publication also includes information on Time Sync Object Attributes.

Configure a Workstation to Operate on an
EtherNet/IP Network
Before you can connect to the device via an Ethernet cable, you must install an
EtherNet/IP driver on your workstation.
A communication driver is required to complete these tasks:
• Upload and download Logix Designer application projects to
Logix 5000™ controllers over an EtherNet/IP network
• Collect controller data for electronic operator interfaces, for example,
PanelView™ Plus terminals, and visualization software, for example,
FactoryTalk®View software
• Update device firmware
• Set or change the IP address.
• Configure the device

communication drivers:
• EtherNet/IP driver:
– Supports runtime communications
– Requires that the workstation is properly connected to the
EtherNet/IP network
– Supports communications over longer distances when compared to
the USB driver
• Ethernet devices driver:
– Requires that you configure the IP addresses to which the software
browses and, therefore, the devices with which the device
communicates
•USBdriver:
– Convenient method to connect to an unconfigured device and
configure the Ethernet port
– Convenient method to connect to a device when the Ethernet port
configuration is unknown
– Convenient method to update the device firmware
– Not intended for runtime connections; it is a temporary-use only
connection with a limited cabling distance
