Linking Device Overview
Chapter 1
About the Linking Device
The 1788-EN2DNR EtherNet/IP-to-DeviceNet linking device lets you
seamlessly connect your information or control-level networks with your
device-level network.
The linking device provides 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 device to do the following:
• As a gateway to connect information or control-level networks to devicelevel networks for programming, configuration, control, or data collection
• As a router/bridge to connect the EtherNet/IP network to the DeviceNet
network
The linking device provides 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 device appears as a single device 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 device also supports Device Level Ring (DLR) and CIP Safety
connections.
Phoenix connectors are provided for power and DeviceNet connections. Two
RJ45 style connectors are provided for EtherNet/IP connection.
The linking device can be mounted to a DIN rail.

IMPORTANT
Configure DeviceNet I/O
Steps 8 and 9 are required only if the linking device is used as an I/O scanner.
The linking device can function as a gateway/bridge for explicit messaging and
safety I/O routing, even if no I/O is configured.
I/O Mapping
The DeviceNet I/O configuration defines the format of the Input and Output
tables, or the mapping of DeviceNet slaves’ I/O data to the I/O tables. As slaves
are added to the linking device’s DeviceNet scanner configuration, the location in
the I/O tables of each part of the slave’s I/O data is determined and stored.
The organization of the I/O tables is very important. I/O tables define the
format of the data that is provided to the EtherNet/IP scanner. Plan and
document the Input and Output table formats to be sure the EtherNet/IP
scanner is working with the correct data from the DeviceNet network.
The size of the I/O data that can be exchanged with the EtherNet/IP scanner
(and, hence, the size of the I/O tables) is restricted as explained below:
• The Input table size cannot be larger than 496 bytes.
• The Output table size cannot be larger than 492 bytes.
• Either table can be empty (0 bytes).
To configure standard DeviceNet I/O, use RSNetWorx for DeviceNet software
to set the linking device’s scan list and I/O table mapping.
To configure CIP Safety I/O, see the following:
• GuardLogix User manual: 1756-UM020H-EN-P - April 2012
• 1791DS User manual: 1791DS-UM001J-EN-P - May 2013
Automap is used in this example for simplicity. In some cases, if you want to
organize the I/O data in other ways, use the Advanced data table editor in the
Input and Output tabs. Refer to RSNetWorx online help for complete details.
1. In RSNetWorx for DeviceNet software, from the Network menu, choose
Online.
2. From the Network menu, choose Single Pass Browse.
Wait for browsing to complete.

Install or Remove the SD Card
Complete these steps to install or remove the Secure Digital (SD) card in the
linking device.
WARNING: When you insert or remove the SD card while power is on, an
electrical arc can occur. This could cause an explosion in hazardous location
installations.
Be sure that power is turned off or the area is nonhazardous before proceeding.
• Verify that the SD card status indicator is off and that the card is not in use
before removal.
• We recommend that you do the following:
- Leave an SD card installed.
- Use the SD cards available from Rockwell Automation (catalog number
1784-SD1 or 1784-SD2).
• While other SD cards can be used with the linking device, Rockwell
Automation has not tested the use of those cards with the linking device. If
you use an SD card other than those available from Rockwell Automation,
there is a possibility of data corruption or loss.
• Also, SD cards not provided by Rockwell Automation do not have the same
industrial, environmental, and certification ratings as those available from
Rockwell Automation.
1. Verify that the SD card is locked or unlocked according to your preference.

Diagnostic Web Pages—
DeviceNet
The following sections explain the diagnostic web pages for the DeviceNet
network.
DeviceNet Status
The DeviceNet Status page presents information about the DeviceNet network
and general DeviceNet diagnostics.
Active Nodes
The Active Nodes page indicates which DeviceNet nodes are currently online on
the DeviceNet network. Nodes that are listed in the scan list are marked ‘Active’.
Nodes that are not in the scan list, but still part of the network, are marked
‘Online’.
Idle Nodes
The Idle Nodes page indicates which DeviceNet nodes are currently in the Idle
state. If a node is Idle, the page displays ‘Idle’ next to the node’s MAC ID. Note
that only nodes configured as slaves to the linking device and the linking device
itself are updated on this page.
Faulted Nodes
The Faulted Nodes page indicates which DeviceNet nodes are currently in a
faulted state. If a node is faulted, the page displays ‘Faulted’ next to the node’s
MAC ID. Note that only nodes configured as slaves to the linking device and the
linking device itself are updated on this page.
A node is considered faulted if the linking device has lost communication or is
unable to establish communication with the node. The actual problem can be
determined by viewing the Node Status web page.
Rockwell Automation Publication 1788-UM059A-EN-P - August 201441
Chapter 6Diagnostic Web Pages
Invalid Nodes
The Invalid Nodes page indicates which DeviceNet nodes are not the correct
device type. If a node’s device type is different than that configured in the scan
list, the page displays ‘Invalid’ next to the node’s MAC ID. Note that only nodes
configured as slaves to the linking device are updated on this page.
Node Status
The Node Status page displays the current status of all DeviceNet nodes that are
configured as slaves to the linking device and the linking device itself. The status
of each node is displayed next to the node’s MAC ID. Note that only nodes
configured as slaves to the linking device and the linking device itself are updated
on this page.
The page displays the status textually for many of the common status values.
However, to save web page size, many of the status values are displayed only
numerically. The table below describes the meaning of each status value.
