Description

The Allen-Bradley 1756-AMXN is a communication bridge module for the ControlLogix platform, specifically engineered to facilitate the integration of legacy Reliance Electric AutoMax Distributed Power Systems (DCS) and Allen-Bradley Remote I/O (RIO) networks into modern control architectures. This module allows for a phased migration strategy, enabling users to upgrade to ControlLogix controllers while maintaining existing field networks and drive racks.

Features

  • Integrated 100 MHz IDT MIPS processor for high-speed protocol conversion.
  • Supports three distinct operating modes: DCS Master, DCS Slave, and RIO Master.
  • Hardware-level support for up to 55 AutoMax DCS slave nodes in Master mode.
  • Dedicated 1 MB logic RAM and 512 KB shared backplane RAM for efficient data handling.
  • Facilitates legacy block transfers and discrete I/O polling for RIO networks.
  • Designed for seamless insertion into standard ControlLogix chassis backplanes.

Applications

This module is primarily used in industrial automation environments where legacy Reliance Electric AutoMax or older Allen-Bradley RIO systems are still in operation. It is ideal for retrofitting drive systems, power distribution control, and legacy I/O networks into modern ControlLogix-based automation environments without requiring a complete system overhaul.

Installation Guidelines

  • Ensure the ControlLogix chassis is powered down before inserting or removing the 1756-AMXN module.
  • Handle the module using ESD-safe practices to prevent damage to internal circuitry.
  • Verify that the module is fully seated in the chassis slot and that the locking mechanism is engaged.
  • Ensure that the communication cable connected to the DB9 port is properly shielded and routed away from high-voltage or high-EMI sources to maintain signal integrity.
  • Configure the module operating mode (DCS Master, DCS Slave, or RIO Master) via the appropriate software configuration tool before commissioning.

FAQ

What is the primary function of the 1756-AMXN?

The 1756-AMXN acts as a bridge between the ControlLogix backplane and legacy AutoMax DCS or Remote I/O networks, allowing for the integration of older hardware into modern control systems.

Can this module communicate with both AutoMax and RIO networks?

Yes, the module is designed to support both AutoMax DCS protocols and Allen-Bradley Remote I/O (RIO) protocols, depending on the configured operating mode.

How many nodes can be supported in DCS Master mode?

In DCS Master mode, the module can coordinate high-speed deterministic messaging for up to 55 AutoMax DCS slave nodes.
