Linking Device Overview

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.

System Requirements

The following hardware and software components are required to use the linking device.

Required Hardware

•1788-EN2DNR linking device

•Two 121 Ω (1%, 1/4 watt) termination resistors (shipped with the linking device)

•DeviceNet cabling, power, and devices forming a DeviceNet network

•Ethernet cabling

Connect the Linking Device to the EtherNet/IP Network

Connect the EtherNet/IP network cable to either of the two RJ45 ports on the front of the linking device.

RJ45 Ports

Connect the Linking Device to the DeviceNet Network

ATTENTION: Do not wire more than two 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.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.

TIP			The two 121 ? termination resistors that come with the linking device are
			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.
