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.

Set the DeviceNet Node Address and Data Rate

Two methods can be used to set the DeviceNet node address and the data rate:
• Use the node address and data rate rotary switches on the side of the linking device
• Use RSNetWorx for DeviceNet software
Set the DeviceNet Node Address and Data Rate by Using the Rotary Switches
The rotary switches are on the right side of the linking device.
Set the desired node address and data rate according to the table below.

TIP
Set the Linking Device IP Address by Using DHCP/BOOTP
The use of DHCP is the default configuration for the linking device as shipped.
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.
Automatic Configuration
Launch a DHCP/BOOTP Server. If using the Rockwell Automation DHCP/ BOOTP server, then follow these steps to change the IP address, Subnet mask, and Gateway address from this dialog box.
1. Click New.
The Properties dialog box appears.
2. Enter the appropriate values into the following boxes.
• Ethernet address (MAC ID) from the linking device product ID label
• IP address
• Subnet Mask
• Gateway (IP address)
3. Click OK.

8. Configure the port settings.
To Th en
Use the default port speed and duplex settings
Manually configure your port’s speed and duplex settings
Consider the following when you configure the linking device’s port settings:
• If the linking device is connected to an unmanaged switch, leave Auto-negotiate port speed and duplex checked or the communications to the linking device fails.
• If you are forcing the port speed and duplex with a managed switch, the corresponding port of the managed switch must be forced to the same settings or the linking device fails.
Leave Auto-negotiate port speed and duplex checked. This setting determines the actual speed and duplex setting.
Follow these steps.
1. Clear the Auto-negotiate port speed and duplex checkbox.
2. From the Current Port Speed pull-down menu, choose a port speed.
3. From the Current Duplex pull-down menu, choose the appropriate Duplex value.
9. Click OK.
Set the Linking Device IP Address by Using the Linking Device Web Pages
The EtherNet/IP address can also be configured by using the Network Configuration web page on the linking device, as shown in the following figure.
