【英文介绍】

Allen-Bradley 1788-EN2DNR Ethernet I/P to DeviceNet link device. This is an externally mounted module with two (2) Ethernet communication ports and one (1) DeviceNet terminal. The module can also act as a CIP security information bridge.

The 1788-EN2DNR Ethernet port supports thirty-two (32) Class 0 connections (secure), 21 Class 1 connections (1 owner-excluded, 20 input/listen only), and sixteen (16) Class 3 connections. It also has an integrated Web server that can be accessed using Microsoft Internet Explorer, Edge, Google Chrome, Mozilla Firefox, and other Web browsers. It also supports a beacon based device-level ring network (DLR) topology.

The 1788-EN2DNR DeviceNet port enables full DeviceNet master device operation, where up to 63 DeviceNet slave devices are connected over Ethernet TCP/IP. The DeviceNet port also supports secure I/O, automatic Device replacement (ADR) with a capacity of 256 KB, fast connections, and I/O slave station messaging, such as bit-strobe, polling, loop, and status change. The scanner configuration for the 1788-EN2DNR can be configured using RSNetworx for DeviceNet.

The 1788-EN2DNR is an IP20 class device compatible with Class 0 CIP secure connections with a maximum latency of 5 ms between networks. The linked device centralizes data stores, input and output tables shared between networks. This device is displayed as a single device on the network using a standard protocol mechanism.

1788-EN2DNR Operating temperature is 0... 60 degrees Celsius (32... 140 °F) and storage temperature -40... 85 °C (-40... 185°F). As an externally mounted device, the module is powered by an external 24V DC SELV/PELV supply voltage. The module is mounted using standard DIN rail.

1788-EN2DNR connected devices are for indoor use only. It should be installed in a housing with appropriate flame retardant properties. The USB port provided on the device is only used for temporary local programming, so it should not be permanently connected. The power supply for the 1788-EN2DNR connected device requires 24 volts DC input voltage with a maximum current of 150 mA. The enclosure of the device has been opened. For power connections, 14 AWG solid or stranded copper wire with a temperature rating of 22 degrees Celsius or higher should be used. For Ethernet connections, 2 or 4 pairs of Class 5e or Class 5 cables should be used. For DeviceNet connections, a 20 AWG 1485C-P1-Cxxx cable should be used.
