Chapter 1
Linking Device Overview
About the Linking Device The EtherNet/IP-to-DeviceNet linking device comes in two designs, the IP20
linking device (catalog number 1788-EN2DNR) and the IP67 linking device
(catalog number 1788-EN2DNROM). These devices let you seamlessly connect
your information or control-level networks with your device-level network.
See 1788-EN2DNR and 1788-EN2DNROM Linking Device Features on
page 12 for information about the products.
The linking devices provide full DeviceNet master functionality, so you can
connect up to 63 DeviceNet slave devices to an Ethernet TCP/IP interface that
supports the EtherNet/IP network and an HTTP web server. For example, you
could use the linking devices to do the following:
•As gateways to connect information or control-level networks to device-
level networks for programming, configuration, control, or data collection
•As routers/bridges to connect the EtherNet/IP network to the DeviceNet
network
The linking devices provide centralized data storage, or I/O tables, for data
shared between the DeviceNet and EtherNet/IP networks. Data is placed into
the I/O tables by one network interface, allowing the data to be read through the
other network interface.
The linking devices appear as single devices on either network by using standard
protocol mechanisms. No special, or extended, protocol features are required for
the devices on either network to read or write the data flowing through the I/O
tables; all cross-network activity is transparent to the devices on either network.
The linking devices also supports Device Level Ring (DLR) and CIP Safety
connections.

The Online Scanlist Changes Allowed in Run (OSCAR) feature lets you
manipulate the DeviceNet scanner configuration while the scanner is in Run
mode. Configuration items that can be changed in Run mode include the
scanlist, ADR, and ISD (InterScan Delay). Safety I/O cannot be added to the
scanlist.

Install the 1788-EN2DNROM Linking Device Chapter 2
System Requirements The following hardware and software components are required to use the linking
device.
Required Hardware
•EtherNet/IP-to-DeviceNet linking device
•DeviceNet cabling, power, and devices forming a DeviceNet network
•Ethernet cabling
•Computer with USB connection or access to the Ethernet network
•24V DC power to the linking device
DeviceNet power can be used; however, using DeviceNet power bypasses
the DeviceNet network isolation.
Required Software
•RSNetWorx for DeviceNet software, version 21 or later, to configure
DeviceNet devices and the linking device’s DeviceNet functionality
•RSLinx® software, version 3.51 or later
•RSLogix™5000 software, version 20 or Studio 5000 Automation
Engineering & Design Environment™, version 21 or later
Connect the
1788-EN2DNROM Linking
Device to the EtherNet/IP
Network
Connect the EtherNet/IP network cable to either of the two D-Code M12 ports
on the front of the linking device.

Connect the
1788-EN2DNROM Linking
Device to the DeviceNet
Network
1. With power to the linking device off, connect the DeviceNet network
cable to the mini-style DeviceNet connector on the linking device.
2. Connect the mini-style power cable to the linking device.
3. Apply power to the linking device and DeviceNet network.
TIP
See the DeviceNet Specification (available from ODVA, Inc at
http://www.odva.org) for specific rules on DeviceNet connections and
termination.
IMPORTANT
On Machine end devices, such as the 1788-EN2DNROM, use the EN-50044 wiring standard while
On-Machine cordsets with flying leads use the SAE-J-1738A standard for wiring. Use care to
follow the pin numbering convention shown below before powering up the unit.

Set the DeviceNet Node
Address and Baud Rate
Two methods can be used to set the DeviceNet node address and the baud rate:
•Use the node address and baud rate rotary switches on the linking device
•Use RSNetWorx for DeviceNet software
Set the DeviceNet Node Address and Baud Rate by Using the
Rotary Switches
Set the desired node address and baud rate using the rotary switches on the
device, according to these tables.
Set the DeviceNet Node Address and Baud Rate by Using RSNetWorx
for DeviceNet Software
See Set the DeviceNet Node Address and Baud Rate on page 46 for information
about using RSNetWorx software to set node address and baud rate.
Set the Linking Device
IP Address
Four methods can be used to set the linking device IP address:
•Use the IP address rotary switches on the linking device
•Use the DHCP protocol
•Use RSLinx software
•Use the web pages of the linking device
