EtherNet/IP-to-DeviceNet Linking Device Introduction

The EtherNet/IP-to-DeviceNet linking device comes in two designs, the IP20 linking device (catalog number 1788-EN2DNR) and the IP67 linking device (catalog number 1788-EN2DNROM). These devices let you seamlessly connect your information or control-level networks with your device-level network. See 1788-EN2DNR and 1788-EN2DNROM Linking Device Features. 

The linking devices provide 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 devices to do the following:

• As gateways to connect information or control-level networks to devicelevel networks for programming, configuration, control, or data collection

• As routers/bridges to connect the EtherNet/IP network to the DeviceNet network The linking devices provide 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吗other network interface. The linking devices appear as single devices 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 devices also supports Device Level Ring (DLR) and CIP Safety connections.
