Overview

CLC/TR 50623:2014 - "Railway applications - Functional Interface Specification - Door System" defines a standardised, vehicle-level functional interface between the external railway door system (including movable steps and ramps) and the Train Control & Monitoring System (TCMS). It covers both the TCMS network interface and the direct I/O interface to conventional train‑lines (safety‑critical signals), and provides UML models and data-type definitions to harmonise control, monitoring and diagnostics across rolling stock.

Key topics

• Scope and architecture
  • Complete external door system (doors, steps, ramps) and its vehicle-level interfaces.
  • Reference architecture showing TCMS bus and conventional train-line connections.
• Functional interface types
  • Control & parameterisation: central open/close, release, lock steps, configuration and behaviour parameters.
  • Monitoring: lifecycle and status attributes (e.g., systemLifesign, closed, released, obstacleDetected).
  • Diagnostics & service: fault attributes, diagnostic operations and service interfaces.
• Door system modes
  • Enumerated modes (e.g., NONE, CLOSED_AND_LOCKED, CLOSED, CLOSING, OPENING, OPENED, EMERGENCY_UNLOCKED, DEACTIVATED) to standardise state reporting.
• Data modelling and UML
  • UML component, deployment and class diagrams, plus common data types and enumeration definitions to support integration and implementation.
• Interfaces & operations
  • Attribute lists, operation commands and parameters (Get/Set services for most parameters) and direct train-line signals (e.g., “Door closed and locked”, “release all left/right doors”).
• Normative references
  • Relies on EN 61131‑3 (programmable controllers) and UIC documents (UIC 556, UIC 558) for train-bus and train-line conventions.

Applications

Who benefits and how:

• Rolling‑stock OEMs - implement consistent door control units (DCUs) and reduce integration effort with TCMS vendors.
• TCMS and vehicle systems integrators - use the FIS to map services, attributes and train-line signals for safe door operation.
• Rail operators & maintainers - gain standard diagnostics and status reporting for maintenance, fault finding and operational procedures.
• Safety and RAMS engineers - use the defined modes, interfaces and UML models to verify behaviour, timing and reliability requirements.
• Software developers - follow the provided data types and UML diagrams for consistent APIs and embedded implementations.

Related standards

• EN 61131‑3:2013 (Programmable controllers - programming languages)
• UIC 556 (Information transmission in the train)
• UIC 558 (Remote control and data cable - RIC coaches)

This Technical Report is a practical reference for anyone implementing or integrating railway door systems, enabling safer, interoperable door control, diagnostics and train-line signalling through a common functional interface specification.

5 Functional description
5.1 General
In this subclause are described the door functions external to the TCMS, which exchange information
with the TCMS over the interface.
The here described interface is a basic standard interface with possibilities of extension (parameters
and services can be added).
If not especially mentioned for each parameter a Set and a Get service is provided.
The function types which are considered are the following:
• Functions for parameterisation;
• Functions for control;
• Functions for monitoring;
• Functions for diagnostics;
• Functions for service.
5.2 Specific requirements on functional interfaces
If deemed useful, the static description of data are completed by:
• Dynamic description, with sequence diagrams, possibly using several interfaces identified in
the reference architecture, for normal and degraded modes. These diagrams may contains
timing requirements (such as time between the command set to TCMS and notification to
remote actuators);
• RAMS requirements to the communication and processing in the TCMS;
• Any other relevant item;
• The physical layer shall be defined later.

The control is supported by services and parameters to influence the behaviour of the system in a
wanted way. The door control and parametrisation functionality uses the TCMS interface to get the
relevant train information (e.g. train mode, time, position).
