Product Description
Allen Bradley 1756-CN2RXT Interface Module product image
System Architecture & Network Logic
The 1756-CN2RXT is a high-availability, redundant-media bridge designed for the ControlNet protocol. This module implements a strict traffic prioritization hierarchy:
  • Primary Priority: Deterministic I/O updates and controller-to-controller interlocking
  • Secondary Priority: Non-scheduled messaging, program uploads, and firmware downloads
Connection Management
  • Total Capacity: 131 logical connections
  • Partitioning: 128 dedicated Logix connections + 3 permanently reserved for redundancy synchronization
  • Operational Note: The 3 redundancy-specific connections remain active even during idle states to ensure immediate failover readiness
Physical Layer & I/O Interface
  • Network Media: Dual BNC ports supporting redundant 1786-RG6 quad-shield coaxial cabling
  • Throughput: Fixed 5 Mbps ControlNet signaling rate
  • Local Configuration: One USB 1.1 Full Speed (12 Mbps) port for local commissioning/bridging
  • Network Scale: Supports a maximum of 99 addressable nodes
Industrial automation components and availability illustration
Waiting 16 weeks for an OEM part isn't just an inconvenience—it's a massive loss in production revenue. At Amikon, we've spent 20+ years building a massive inventory buffer for the industry. We are not just another broker; we are a major stockist of PLCs, DCS, and HMI components that original manufacturers often list as "backordered" or "discontinued."
Our Value Proposition
  • Hard-to-Find Components: We specialize in EOL (End-of-Life) and obsolete hardware that's impossible to find elsewhere
  • Ready Inventory: Most parts are on our shelves right now with global fast shipping
  • Competitive Pricing: Get surplus pricing without the "new-from-factory" wait times
Don't let a faulty module kill your uptime.
