CiA® 421 series: Profiles for train vehicle control systems

The document CiA 421 train vehicle control network describes the communication via the in-vehicle integration network. This profile describes which application data has to be provided to the in-vehicle integration network by a certain sub-system. In case e.g. all doors shall be closed, the train operating system needs to know, where to hand over the command to the door control system. From a CANopen point of view, this means to which object in the object dictionary of the door controller the train operating system has to write the “close all door command”. In addition, the door controller needs to know the structure of the command (e.g. which bit covers the demanded action). This information is standardized in the document CiA 421. In addition, the in-vehicle integration network may be connected to a WTB-based train control network via a gateway device. In order to minimize the formatting effort within such a gateway device, the data defined in CiA 421 was harmonized with those defined in UIC leaflet 556.

The CiA 421 series of documents specifies virtual device interfaces for sub-systems used in locomotives, power-cars, and coaches. This application profile is part of a virtual multiple network architecture. It is the higher hierarchical virtual network on vehicle sub-level that connects a number of sub-systems. In order to support every physical network architecture, no PDOs have been predefined. The virtual interfaces of the sub-system are described in:

  • 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
  • Part 18: Slip/slide control system

CiA 421-1 version 1.0.0 CANopen application profile for train vehicle control systems - Part 1: General definitions
Scope

This application profile defines the communication between virtual devices within locomotives, power cars as well as coaches. It is intended to use the application profile for urban and regional rail vehicle transportation system as well as long-distance rail vehicle transportation systems including high-speed trains. But it is not limited to these railway applications, e.g. it is also used in cargo train locomotives and cargo train wagons as well as other railway transportation systems, such as commuter trains, subway trains, etc. The set of specifications is organized as follows: • Part 1: General definitions; • Part 2: Train operating system (TOS); • Part 3: Monitoring and safety system (MSS); • Part 4: Auxiliary operating system (AUX): • Part 5: Power (drive) system (PDS); • Part 6: Running gear system (RGS); • Part 7: Brake control system (BCS); • Part 8: Ancillary operating system (ANC); • Part 9: Vehicle linkage system (VLS); • Part 10: Exterior lighting system (ELS); • Part 11: Interior lighting system (ILS); • Part 12: Door control system (DCS); • Part 13: HVAC system (HS); • Part 14: Passenger information system (PIS); • Part 15: Cargo superstructure system (CSS); • Part 16: Diagnostic system (DS); • Part 17: Train-to-ground communication system (TCS); • Part 18: Slip/slide control system (SCS). CANopen devices compliant to this application profile use communication techniques, which conform to those described in the CiA Draft Standard 301.

CiA 421-9 version 1.0.0 CANopen application profile for train vehicle control systems - Part 9: Vehicle linkage system
Scope

This part of the CANopen application profile for rail vehicles describes the CANopen interface of the vehicle linkage device. Via this interface all required data is exchanged that is relevant to control full automatic couplings. Full automatic couplings handle all connections between the rail vehicles such as e.g. electrically or electrical automatically, without human interaction.
