Getting Started Chapter 1
Safety Precautions Read the following safety precautions carefully.
ATTENTION: Risk of injury or equipment damage exists. If the adapter is
transmitting control I/O to the end device, the end device can fault when you
reset the adapter. Determine how your end device responds before resetting an
adapter.
ATTENTION: Risk of injury or equipment damage exists. Various parameters in
the end device let you determine the action of the adapter and connected end
device if I/O communication is disrupted or the controller is idle. By default,
these parameters turn off the outputs of the connected E3 Plus and 825-P. You
can set these parameters so that outputs react as desired (for example, to keep
the motor running). Take precautions to be sure that the settings of these
parameters do not create a risk of injury or equipment damage. When
commissioning the end device, verify that your system responds correctly to
various situations (for example, a disconnected cable or a faulted controller).
ATTENTION: Risk of injury or equipment damage exists. When a system is
configured for the first time, there can be unintended or incorrect machine
motion. Disconnect the motor from the machine or process during initial system
testing.
ATTENTION: Risk of injury or equipment damage exists. The examples in this
publication are intended solely for purposes of example. There are many
variables and requirements with any application. Rockwell Automation, Inc.
does not assume responsibility or liability (to include intellectual property
liability) for actual use of the examples shown in this publication.

Chapter 2
Install the Adapter
This chapter provides instructions for installing the adapter.
Prepare for an Installation Before installing the adapter, refer to these guidelines:
•Make sure the Ethernet switch is the correct type. A managed switch that
supports Internet Group Management Protocol (IGMP) snooping is
usually recommended. An unmanaged switch can be used instead if
RSLogix 5000 software, version 18 or later, is used and all devices on the
network are configured for unicast I/O. For more details, see the following
documents:
–EtherNet/IP Media Planning and Installation Manual, ODVA
publication 148
–EtherNet/IP Network Infrastructure Guidelines, ODVA publication
35
–Ethernet Design Considerations Reference Manual, Rockwell
Automation publication ENET-RM002
•Understand IGMP Snooping/Ethernet Switches
The 2100-ENET adapter is a multicast device. In most situations, an
IGMP snooping (managed) switch is required. If more than one
2100-ENET adapters are connected to the switch, a managed switch is
required—otherwise the end device can fault on a communication
(comms) loss. The 2100-ENET adapter, RSLogix 5000 software,
version 18 or later, and a ControlLogix® or CompactLogix™ controller
supports unicast. When all Ethernet connections are set up as unicast
devices in RSLogix 5000 software, then an IGMP snooping (managed)
switch is not needed.
Much of EtherNet/IP network implicit (I/O) messaging uses IP
multicast to distribute I/O control data, which is consistent with the
CIP producer/consumer model. Historically, most switches have
treated multicast packets the same as broadcast packets. That is, all
multicast packets are re-transmitted to all ports.

Chapter 2 Install the Adapter
IGMP snooping constrains the flooding of multicast traffic by
dynamically configuring switch ports so that multicast traffic is
forwarded only to ports associated with a particular IP multicast group.
Switches that support IGMP snooping (managed switches) learn which
ports have devices that are part of a particular multicast group and
forward only the multicast packets to the ports that are part of the
multicast group.
Be careful as to what level of support a switch has of IGMP snooping.
Some layer 2 switches that support IGMP snooping require a router,
which could be a layer 3 switch, to send out IGMP polls to learn what
devices are part of the multicast group. Some layer 2 switches can use
IGMP snooping without a router sending polls. If your control system
is a stand-alone network or is required to continue performing if the
router is out of service, make sure the switch you are using supports
IGMP snooping without a router being present:
•Refer to Appendix A for the number of CIP connections supported
by the 2100-ENET adapter.
•Verify that you have all required equipment. Refer to Required
Equipment on page 10.

Follow these steps to connect the adapter to the network.
1. Connect one end of an Ethernet cable to the network.
See following graphic for an example of wiring to an EtherNet/IP
network.
Connecting the Ethernet Cable to the Network
2. Route the other end of the Ethernet cable to the EtherNet/IP network
connector on the bottom of the 2100-ENET adapter.
Apply Power Connect 24V power to the DC+ connector on the bottom of the 2100-ENET
adapter. When power is supplied to the adapter for the first time, its topmost
status indicator is steady green or flashing green after an initialization. If it is red,
there is a problem. Refer to Troubleshooting, Chapter 7.
Start-up Status Indications
After power has been applied, the status indicators can be viewed on the front of
the 2100-ENET adapter (Figure 2).

Chapter 2 Install the Adapter
After installing the adapter and applying power, refer to Tab le 8 on p ag e 5 8 for a
description of the status indicators.
Commission the Adapter To commission the adapter, you must set a unique IP address on the network.
(Refer to the Glossary for details about IP addresses.) After installing the adapter
and applying power, you can set the IP address by using a BOOTP server or by
setting adapter parameters. See Chapter 3 for details.
By default, the adapter is configured so that you must set the IP address by using a
BOOTP server. To set the IP address by using adapter parameters, you must
disable the BOOTP feature. See Using BOOTP on page 17 for details.

Configure the Adapter
This chapter provides instructions and information for setting up the adapter.
For a list of E3 Plus or 825-P parameters, refer to the appropriate user manual.
For definitions of terms in this chapter, refer to the Glossary.
Configuration Tools The adapter does not have any parameters that need to be configured. The only
items that need to be configured are the IP Address, Subnet Mask and Gateway
Address. This can be done only with a BOOTP Server.
Using BOOTP By default, the adapter is configured so that you can set its IP address, subnet
mask, and gateway address by using a BOOTP utility. You can select from a
variety of BOOTP utilities. These instructions use the Rockwell Automation
BOOTP Server, version 2.3 or later, a free standalone program that incorporates
the functionality of standard BOOTP utilities with a graphical interface. It is
available from http://www.software.rockwell.com/support/download/
detail.cfm?ID=3390. Refer to the Read Me file and online Help for directions
and more information.
