Allen-Bradley 1734-AENTR POINT I/O Dual-Port EtherNet/IP Adapter Module

The Allen-Bradley 1734-AENTR is a high-performance, dual-port EtherNet/IP communication adapter designed for Rockwell Automation’s POINT I/O platform. Weighing 0.62 lbs (0.28 kg), this head module mounts on the far-left position of a POINT I/O assembly to interface up to 63 local expansion I/O modules with central programmable automation controllers (PACs) across high-speed industrial Ethernet networks.

Key Network & Topological Features

Equipped with two embedded RJ-45 Ethernet ports with integrated switching capability, the 1734-AENTR supports Device Level Ring (DLR), linear/daisy-chain, star, and tree network topologies at 10/100 Mbits/s auto-negotiating speeds. Powered by a 24V DC external supply, it features reverse polarity protection, 50V continuous isolation, and accommodates up to 31 direct controller connections for multi-master scanner architecture.

IP Addressing & Configuration Options

  • Rotary Thumbwheel Switches: Quickly set static IP host values (1–254) directly on the front panel using the hardware switches for predictable, non-volatile addressing.
  • BOOT-P / DHCP Server Utility: Assign dynamic or fixed IP addresses over the network using Rockwell's BOOT-P/DHCP tool during commissioning.
  • Static IP Best Practice: Always assign a static IP address in production environments to avoid communication losses caused by dynamic address lease renewals or power cycles.

Frequently Asked Questions

Q1: How many expansion modules can be controlled by a single 1734-AENTR adapter?
A1: A single 1734-AENTR adapter supports up to 63 POINT I/O expansion modules on its backplane (expansion power power-supply modules may be required for large nodes).

Q2: What is the primary difference between the 1734-AENT and 1734-AENTR adapters?
A2: The 1734-AENTR includes 2 embedded Ethernet ports supporting Device Level Ring (DLR) and fault-tolerant ring topologies, whereas the 1734-AENT features a single Ethernet port.

Q3: What cable types are recommended for connecting the 1734-AENTR to an EtherNet/IP network?
A3: Standard Category 5 or Category 6 industrial-grade twisted-pair Ethernet cables with RJ-45 connectors should be used.
