B&R X20CP1484

Product Series: B&R X20 I/O System (X20CP Series)

Product Introduction: The X20CP1484 is a POWERLINK communication processor module that serves as the dedicated interface between a B&R X20 CPU (e.g., X20CP0484, X20CP3484) and a POWERLINK real-time Ethernet network. It offloads all POWERLINK protocol processing from the CPU, enabling deterministic cyclic data exchange with nanosecond-level synchronization.

  • Printing and converting machines
  • Semiconductor wafer handling
  • Power generation (turbine control)
  • Railway signaling and traction control

Installation Requirements:

  • Must be mounted in the same X20 rack as the X20 CPU module
  • Connect RJ45 to POWERLINK network using shielded CAT5e/CAT6 cable
  • Maximum segment length: 100 m (100 Mbps)
  • Terminate line ends with 120 Ω resistor

Usage Precautions:

  • This module requires an X20 CPU — it cannot operate standalone
  • Use only shielded twisted-pair cable for POWERLINK connection
  • Do not connect POWERLINK port to standard Ethernet switch port (VLAN separation required for mixed traffic)
  • Ensure POWERLINK master acknowledges this node before startup

Advantages & Highlights:

  • Hardware-based POWERLINK stack — zero CPU load for real-time communication
  • IEEE 1588v2 synchronization < 1 μs — industry-leading precision
  • Galvanic isolation protects CPU from network transients
  • On-board web server enables remote diagnostics without engineering software
