6 Ethernet-to-DeviceNet Linking Device
About the Linking Device
The 1788-EN2DN Ethernet-to-DeviceNet linking device lets you seamlessly connect your informationor 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. As examples, you could use the linking device:
•as a gateway to connect informationor control-level networks to device-level 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.
All connections, whether power or fieldbus, to the linking device are made on one end of the module. Phoenix connectors are provided for power and DeviceNet connections. A RJ45 style connector is provided for EtherNet/IP connection.
The linking device can be mounted to a DIN rail.

TIP |
Two 120 ohm termination resistors (supplied with the linking device) may be |
||||
|
required for proper network termination at each end of the trunk line. See the |
||||
|
DeviceNet Specification (available from the Open DeviceNet Vendors |
||||
|
Association at http://www.odva.org) for specific rules on DeviceNet |
||||
|
connections and termination. |
||||
4. Apply power to the linking device and DeviceNet network.
IMPORTANT |
The linking device defaults to Autobaud. This means that the linking device |
|
automatically finds the network communication rate at when power is |
|
applied. You must specify a master device, such as a DeviceNet Bridge Module |
|
(catalog number 1756-DNB) so that the linking device can pick up the correct |
|
communication rate. If you do not have another device installed, you must |
|
use RSNetWorx for DeviceNet software to set the communication rate, as |
|
described in Set the DeviceNet MAC ID and Communication Rate on page 21. |
|
Do not attempt to commission the linking device on a network configured at |
|
a different communication rate. |

Configure the Linking Device IP Address
Several methods may be used to set the IP Address. These methods include the following:
•IP address configuration DIP switch
•DHCP protocol
•Web page
•RSLogix 5000 software, version 13 or later), and 1788-EN2DN Linking Device, revision 2.x or later
Setting the IP Address with the Configuration DIP Switch
A configuration DIP switch on the end of the linking device lets you set the IP address. If the configuration DIP switch is set to 1 (in the up position, as shown in the following figure), when power is applied to the switch, the value of the switch creates the IP address of 192.168.1.1.
IMPORTANT |
The numbers that appear above the switches on the DIP switch do not |
|
correspond to bit locations in the address value. The numbers on the switch |
|
are opposite the address value bit locations; for example, bit 0 is set by |
|
switch 8. |

16 Ethernet-to-DeviceNet Linking Device
Setting the IP Address Using By Using the Web Page
The EtherNet/IP address can also be configured using the IP Configuration web page on the linking device, as shown in the following figure.
The IP address can be set with the web page only if the linking device already has a valid IP address. Typically, you can do this by using the DIP switch to force the linking device to use a temporary IP address after you cycle power. Follow these steps to configure the IP address with the web page.
IMPORTANT |
Because the DIP switch setting overrides other IP address configurations, be |
|
sure to set the DIP switch to the 0 position before continuing. |
|
|
1.Browse to the linking device by entering the temporary IP address in your web browser’s address bar and click Enter.
2.In the left pane, click IP Configuration.
You see the Enter Network Password dialog box.
3.In the Username field, enter Administrator.
