Allen-Bradley 1747-AENTR Ethernet/IP Communication Module

Product Overview

The Allen-Bradley 1747-AENTR is an Ethernet/IP communication module for SLC 500 systems. It allows CompactLogix and ControlLogix processors to control SLC I/O modules. This module replaces the SLC processor in the chassis. It acts as a gateway between SLC and Ethernet/IP backplanes. The 1747-AENTR uses two embedded Ethernet ports. These ports support 10/100 Mbps speeds. They work in half or full duplex mode. You can use star, tree, daisy chain, or ring topologies. This module is a CIP server on Ethernet and a host on the SLC backplane. It simplifies migration from old SLC systems to modern Logix platforms.

Application Scenarios

Use the 1747-AENTR to upgrade existing SLC 500 installations. It works well in manufacturing plants. It connects remote I/O racks to a central Logix controller. Use it in distributed control systems. It supports both new installations and retrofits. The module fits in slot 0 of a 1746 chassis. It replaces the original SLC processor or adapter modules. It works with CompactLogix and ControlLogix controllers. The dual ports enable redundant network paths. It is ideal for applications needing high availability.

Installation & Maintenance Guide

Install the 1747-AENTR in the leftmost slot of the SLC chassis. Remove the existing processor or adapter. Insert the module and secure it. Configure the IP address, subnet mask, and optional gateway. Use a Category 5 shielded or unshielded cable. Connect to an Ethernet/IP network. The module works with star, tree, linear, and ring topologies. For maintenance, check LED indicators for status. Keep firmware updated. Protect the module from moisture and extreme temperatures. Clean only with a dry cloth. Do not open the module housing. If issues occur, verify network settings and cable connections. Replace only with authorized parts.
