Product Summary
The Allen-Bradley 1747-AENTR acts as a crucial bridge for system migration. This module replaces legacy SLC 500 processors directly. It allows modern CompactLogix or ControlLogix controllers to manage existing SLC I/O modules. You gain Ethernet/IP connectivity without replacing your entire rack. This solution protects your hardware investment.
Why Choose the 1747-AENTR for Your Migration
The Smart Path to Modern Control
Migrating to a Logix platform does not require a full system overhaul. The 1747-AENTR fits directly into slot zero of your SLC chassis. It replaces the old processor and scanner modules seamlessly. Your existing 1746 I/O modules remain in place. This approach saves significant capital and reduces downtime. Engineers avoid the complexity of rewiring an entire cabinet.
Solving Real Industrial Pain Points
Procurement managers face pressure to modernize without waste. The 1747-AENTR solves this by reusing valuable installed I/O. Application engineers gain the advanced functionality of Logix controllers. You retain the rugged reliability of the SLC backplane. This module transforms a legacy system into a distributed I/O station. It connects via two embedded RJ-45 ports for flexible topology.
Step-by-Step Installation Guide for the 1747-AENTR
Preparing Your SLC 500 Chassis
First, power down the entire control system completely. Remove the existing SLC 500 processor from the leftmost slot. This slot is reserved exclusively for the new adapter module. Verify the chassis backplane is clean and undamaged. Ensure no debris obstructs the electrical connectors.
Mounting the Module
Insert the 1747-AENTR into the designated slot zero position. Press firmly until the module locks into the backplane. Secure the module using the retention screws provided. The dimensions are 5.72 x 1.37 x 5.15 inches. Ensure adequate airflow for cooling. The operating temperature range is 0 to 60 degrees Celsius.
Configuring Network Parameters
You must assign an IP address, subnet mask, and gateway. Use the module's web interface or BOOTP utility for setup. Connect a Category 5 cable to one of the dual ports. The communication speed is 10/100 Mbps in half or full duplex. This module supports Star, Tree, Linear, and Ring topologies. Choose the topology that fits your network architecture.
Establishing Communication with Logix
Configure your CompactLogix or ControlLogix controller as the scanner. The 1747-AENTR acts as a CIP server on the Ethernet port. It functions as the SLC host on the backplane side. Add the module to your I/O configuration tree. Map the SLC I/O points to the Logix controller tags. The backplane current draw is 470 mA at 5 Volts DC.
