ICS Triplex 56AMXN

Product Introduction: The 56AMXN is an Allen-Bradley ControlLogix communication interface module manufactured by Rockwell Automation. It is designed to connect ControlLogix systems to AutoMax DCS networks or AutoMax remote I/O networks, serving as a communication bridge between modern ControlLogix platforms and traditional Reliance Electric Systems based on AutoMax controllers and architectures. DCSNet functions as the primary communications, data, and control network backbone.

Working Principle: The 56AMXN operates as a protocol gateway within the ControlLogix chassis. The 100 MHz MIPS processor manages communication between the ControlLogix backplane and the AutoMax DCSNet or Remote I/O network. Data from ControlLogix programs is formatted into DCSNet protocol frames for transmission to legacy devices, while incoming network data is translated into ControlLogix tag structures. The shared RAM buffer enables high-speed data exchange between the network processor and the ControlLogix controller.

Installation Requirements:

  • Install in approved ControlLogix chassis slot
  • Configure through RSLogix 5000 software before operation
  • Connect to AutoMax network using appropriate cabling
  • Verify module keying matches chassis slot
  • Establish proper grounding through chassis installation

Usage Precautions:

  • Verify firmware compatibility with ControlLogix controller revision
  • Monitor backplane current loading to prevent power supply overload
  • Configure RPI settings appropriate for network load
  • Do not operate outside specified temperature range
  • Follow anti-static handling procedures during installation
