  • Dual Ethernet: one for I/O bus, one for IT/HMI/programming
  • CompactFlash-based OS — fast boot, easy backup/recovery
  • Integrated web server for remote diagnostics
  • Supports X20 and X67 I/O systems simultaneously
  • SoftPLC (PLC runtime) integrated in Automation Runtime
  • Motion control (CNC, robotics) via software libraries

Applicable Industries:
Machine building, packaging, printing, plastics, robotics, CNC, semiconductor, food and beverage, pharmaceutical.

Installation Requirements:

  • Mount on DIN rail TS 35
  • Connect 24 V DC power via dedicated terminal block (19.2–28.8 V DC)
  • Ethernet 1: connect to X20/X67 I/O bus (shielded Cat 5e or better)
  • Ethernet 2: connect to HMI, programming PC, or IT network
  • VGA output: connect to B&R Panel or external monitor
  • RS-232: connect for initial commissioning and diagnostics

Usage Notes:

  • Use B&R-approved CompactFlash card (industrial grade)
  • Do not disconnect power during CompactFlash write operations
  • Ensure 24 V DC supply is stable — voltage dips below 19.2 V cause brownout
  • Backup CompactFlash image regularly via Automation Studio
  • Fanless design — ensure adequate cabinet ventilation
