About the Linking Device

The 1788-EN2DN Ethernet-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. As examples, you could use the linking device:
as a gateway to connect information- or 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.

Installing and Configuring the Linking Device

WARNING: If you connect or disconnect the communication cable with power
applied to this module or any device on the network, an elec trical arc can occur. This could cause an explosion in hazardous location installations.
If you connect or disconnec t wiring while the field-side power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.
When you change switch settings while field-side power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
Follow these steps to install the linking device (described in the sections that follow).

Connect the Linking Device to the EtherNet/IP Network

Connect the EtherNet/IP network cable to the RJ45 port on the end of the linking device.
ATTENTION: This product is grounded through the DIN rail to chassis ground. Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding. Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.) and use end-anchors appropriately.

ATTENTION:
Do not wire more than 2 conductors on any single terminal. To comply with the CE Low Voltage Directive (LVD), this equipment must be
powered from a source compliant with Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).
To comply with UL restrictions, this equipment must be powered from a source compliant with Class 2 or Limited Voltage/Current.
1. Make sure a computer running RSNetWorx for DeviceNet software is
connected to the EtherNet/IP network.
2. With power to the linking device off, connect the DeviceNet network
cable to the DeviceNet connector on the linking device.
The female terminal block connector is provided with the linking device.

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.
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 Do not attempt to commission the li nking 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
We b p ag e
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.
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.

Ethernet-to-DeviceNet Linking Device 13
TIP
The switch represents the binary value of the last byte in the 4-byte IP address. In this case it is n. If n = 0, the linking device obtains its IP address from the software configuration (DHCP or web page).
IP address 192.168.1.n
Subnet mask 255.255.255.0
Gateway address 0.0.0.0 (No gateway set)
Setting the IP Address By Using DHCP/BootP
The use of DHCP is the default configuration for the linking device as shipped. The IP address configuration DIP switch ships with n =0.
When DHCP/BootP is enabled and a DHCP or BootP server is found, the IP address, Subnet mask, and Gateway address are automatically configured by the DHCP server, as shown in the following figure.

IMPORTANT
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.
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.
