CiA 421 series of documents: CANopen application profile for train vehicle control systems

The CiA 421 series of documents specifies virtual device interfaces for sub-systems used in locomotives, power-cars, and coaches. The virtual devices provide gateway functionality to sub-layered control networks. No PDO communication is pre-defined. The following sub-system interfaces are specified or are under development:

  • Part 1: General definitions
  • Part 2: Train operating system
  • Part 3: Monitoring and safety system
  • Part 4: Auxiliary operating system
  • Part 5: Power (drive) system
  • Part 7: Brake control system
  • Part 8: Ancillary operating system
  • Part 9: Vehicle linkage system
  • Part 10: Exterior lighting system
  • Part 11: Interior lighting system
  • Part 12: Door control system
  • Part 13: HVAC system
