1.1 Introduction
EtherNet/IP™ is the most commonly used industrial communication protocol managed by Open
DeviceNet Vendors Association (ODVA). EtherNet/IP is an application layer protocol that is
transferred inside a TCP/IP Packet. That means that EtherNet/IP is simply the way data is organized in
a TCP or UDP packet. EtherNet/IP is part of CIP, the Common Industrial Protocol. CIP defines the
Object structure and specifies the message transfer. CIP protocol over Ethernet is EtherNet/IP.
This document describes how to enable EtherNet/IP protocol support in Smart Wireless Gateway
(Gateway). This document also explains the procedure to import Order Options, enable protocol
support, and establish various types of connections with Rockwell ControlLogix
UCMM, and Class3 connections.
The document also explains about understanding different user interface pages within the Smart
Wireless Gateway. These pages include, EtherNet/IP statistics, the communication page, and how to
map device variables in the EtherNet/IP mapping page. It is assumed that there is general knowledge
of how to establish connections using the Rockwell ControlLogix PLC. Consult the manual for the
specific PLC. This document is just aimed at users looking to incorporate data values from the Smart
Wireless Gateway. For assistance, contact your local wireless specialist.

1.2 Preparing the Gateway for EtherNet/IP connection
1.2.1 Importing EtherNet/IP Order Option
Before importing the order option
Note
If the Gateway was pre ordered with the EtherNet/IP option, skip to “Enable EtherNet/IP
Protocol” on page 4. If this is a field upgrade, follow these directions. An option file will need to
be purchased for all field upgrades. Contact your local Emerson representative or contact
information at the end of this manual.

Once an option file has been obtained navigate to Setup>Firmware options. Under Select a
Gateway option file, browse to the option file. See Figure 1-1 on page 2.
After selecting the EtherNet/IP order option file associated with the correct Gateways HG serial
number, select the Submit button to apply the changes and proceed to Restart the Applications
as seen below in Figure 1-2.
An application restart is necessary for the installation to be complete. Navigate to
Setup>Restart Applications if not prompted.
Note
This will result in a temporary loss in communications with the network and will require a
network rebuild. The mesh network is maintained, however, the devices will need to establish a
connection to the Gateway. WARNING - All communications back to the host will be lost.

1.2.2 Enable EtherNet/IP Protocol
Navigate to the Setup>Security>Protocols page to enable the EtherNet/IP Protocol. The
Gateway needs to restart in order to apply the changes.
Select the Enable checkbox and press the Submit button to enable the EtherNet/IP Protocol in
the Gateway as shown below. Restart the application to apply the changes.
Navigate to Setup>Security>Protocols page. Ensure that the EtherNet/IP Protocol checkbox is
enabled as shown in the below screenshot and that there are no error messages on the Protocol
Page. A browser reset/cache clear may be required for the option to fully display.

1.2.3 EtherNet/IP Web Pages
EtherNet/IP mapping page
Navigate to the Setup>EtherNet/IP>EtherNet/IP Mapping page to map various device
variables in Instance Pairs (100-101 or 102-103 or 104-105).
Note
If no devices are configured with the Gateway or if all devices are offline, enable the Include
Gateways option from the HART>Hierarchy page for initial EtherNet/IP communication with the
Smart Wireless Gateway. In that case, the user can map wihartgw.PV, wihartgw.QV, etc. This web
page is also useful while reading values from ControlLogix to understand in which pair and as
which member user has mapped his particular device variable.
Below represents the EtherNet/IP mapping page of the Gateway. See Table 1-1 on page 1-5 for
detailed explanations of the available options.

1.3 Connecting to the ControlLogix PLC
This section assumes knowledge of Allen-Bradley software. The IO Module is configured with a
valid IP address on the same subnet as the Gateway and the PC.
A basic knowledge of the Emerson Smart Wireless Gateway is required. The Gateway will need
to be configured with a valid IP address on the same subnet as the Allen-Bradley control system
and the PC.
The Emerson 1420 device uses multiple Class 1 CIP connections within a Generic Profile. The
latest version of RSLogix5000 is required for you to use this capability. This requires V19 and
higher of RSLogix5000. V20 of RSLogix5000 includes features that automatically populate
parameters such as for input/output instances for the Generic CIP Module making some of the
steps in this manual unnecessary.
Note
The PLC processor has to be taken offline to be configured, then downloaded to accept
the EtherNet/IP setup. This means the protocol can't be implemented when the process
is running.
EtherNet/IP can only be implemented on ControlLogix processor firmware revision 17
and up.
Manual Supplement
00809-0500-4420, Rev BB
EtherNet/IP will only work on the Ethernet 1 connection on the Gateway.
When mapping data, only use one input “instance” and one output “instance”. An
Allen-Bradley Ethernet card can only handle one instance per setup in the PLC.
EtherNet/IP can only be implemented on redundant ControlLogix processors starting
with firmware revision 20 and above.
See “Other information” on page 36 for limitations with explicit messaging before
proceeding.
Section 1.3.2, 1.3.4, 1.3.5 and 1.3.6 detail connecting to the ControlLogix PLC using four
separate methods, Class 1 Connections: CIP BUS Module, UCMM Connection, Class 3
Connections and Generic Gateway Module respectively. The methods are defined below. Use
only one of these methods to connect to the PLC.
Class 1 Connections (I/O): CIP BUS Module - Establishes a periodic exchange of data between a
scanner and an adapter. Messages are sent as connected messages which utilize resources
within each node that are dedicated in advance to a particular purpose. The messaging is
implicit and is time-critical in nature. Implicit messaging (or I/O) is typically used for real-time
data exchange when speed and low latency is important. They include very little information
about their meaning so its transmission is more efficient, but less flexible than explicit.
UCMM Connection (explicit messaging - unconnected) - Commands or data requests sent
from the scanner to individual target nodes (Class 3 messages). Unconnected messaging is used
during connection establishment and for infrequent, low-priority messages. The Unconnected
Message Manager, or UCMM, refers to the unconnected resources in a device. Explicit
messaging connections in general are request-response transactions between two nodes
typically used for non-real time data, normally for information. They include a description of
their meaning so the transmission is very flexible but less efficient.

Class 3 Connection - Similar to UCMM connection Class 3 connection is used for individual
request/response transactions. A request from a scanner always results in a response from the
adapter indicating the success or failure of the request. Messaging is explicit and connected
rather than unconnected.
Generic Gateway Module - Similar to CIP BUS Module the Generic Gateway Module is
established to move application specific I/O data at regular intervals. The Generic Gateway
Module however establishes class 1 connection to a single pair at a time whereas the Ethernet
CIP BUS Method allows connection to multiple pairs.
For status and output capability, the use of the CIP Bus method is recommended. It should be
noted that the CIP Bus method does require more memory than the generic Gateway method.
These are just examples of ways to bring in the data from the network. There are many possible
configurations.
Note
For instructions on how to first establish a connection to the Gateway, see either the Quick Start
Guide (document number 00825-0200-4420) or the Smart Wireless Gateway manual
(document number 00809-0200-4420).

1.3.1 Importing Smart Wireless Gateway EDS file using EDS
hardware installation tool
Note
Before doing connections with the controller, the user should import the EDS file of the Smart
Wireless Gateway in RSLogix. Navigate to Start>Programs>Rockwell Software>Version 2.56
>RSLinx>Too l s>EDS Hardware Installation Tool. The .eds file can be obtained by contacting
Specialist-Wireless.EPM-RTC@EmersonProcess.com with Allen-Bradley EDS file in the subject line.
Equipment used
