Verify EULYNX Compliance

Relesoft Test Center

Relesoft Test Center is an ISO/IEC 17025 – compatible system to verify the EULYNX compliance of object controllers, interlockings and CTC systems. It offers independent EULYNX development support, and national or project-specific testing capability.

  • Manufacturers can increase development speed and decrease cost by detecting EULYNX compliance issues early.
  • Infrastructure managers have capability for national or project-specific testing of EULYNX compliance.

Designed and implemented by leading European EULYNX and testing experts, Relesoft Test Center is the official testing system and test case database of the EULYNX Consortium Office. It includes the latest EULYNX compliance test catalogs and supports many variability options.

Use case examples

SCI
  • Testing SCI.XX-PDI of any EULYNX – compatible system
  • Testing SCI-P, SCI-LS, SCI-IO, SCI-TDS, SCI-LX and SCI-LC for object controllers
  • Testing SCI outside happy path, including telegram errors, protocol errors and bad network conditions
  • Testing SCI-CC, SCI-RBC and SCI-ILS for interlockings with a virtual traffic location
  • Testing SCI-CC for CTC with a virtual traffic location
SDI, SMI, SSI
  • Testing SDI by reading and checking state information over OPC UA
  • Testing SMI by performing data item preload and activation over OPC UA
  • Testing SSI-PKI client to verify its ability to request X.509 certificates with CMP over HTTP
  • Using SSI-LOG – compatible Syslog over TLS server (SCS-LOG) to relay safety-related messages into a SIEM system for collection and analysis
RaSTA
  • Testing Mutual TLS authentication for RaSTA and OPC UA to establish and use a TCP+TLS connection
  • Verifying the correct implementation of RaSTA (UDP and TCP+TLS)

ISO/IEC 17025 compliance
  • Clear and easy-to-read, ISO/IEC 17025-compliant test reports and technical records to support the technical development
  • User authentication and authorisation for various testing and ISO/IEC 17025-related roles

Provision a Virtual Traffic Location for Interlocking Testing

Relesoft Infrastructure Simulator complements the Relesoft Test Center by providing a virtual environment or a digital twin for testing EULYNX-compatible interlockings and CTC systems. It provisions an EULYNX-compatible traffic location using Relesoft Reference Object Controllers, field element emulators and IO bridges, enabling comprehensive testing. Key features of the Relesoft Infrastructure Simulator include:

  • Configuration and launching a virtual traffic location to test EULYNX-compatible interlockings (SCI-CC, SCI-RBC, SCI-ILS) and CTC (SCI-CC)
    • Configure and launch any number of Relesoft Reference Object Controllers, IO bridge emulators and field element emulators
    • Scriptable logic for field element emulators
  • Verification of legal route setting with respect to the field element emulator states

Relesoft Reference Object Controller (RROC) is an EULYNX field element Subsystem (Object Controller) specifically designed to support testing and development of EULYNX-compatible systems. It adheres strictly to the EULYNX standard and is implemented with maximum rigour against the EULYNX functional definition. Every state update of each functional entity is logged, up to the individual trigger port names in the EULYNX SysML modelling format, making external validation possible. RROC supports all EULYNX field element Subsystem types (P, IO, LS, LC, LX, TDS (AC, TC, TDP)), cardinalities (single type, multi type, single element, multi element, …) through configuration and interfaces (SCI, SDI, SMI, SSI).

Relesoft Infrastructure Simulator and its constituents are included in the Relesoft Test Center as a dedicated component called Infrastructure Engine.

System Architecture

System Delivery Variants

Local Dedicated Installation

Local Dedicated Installation is a self-containing, complete installation of Relesoft Test Center. It includes a local deployment of all hardware and software components. The system can be completely isolated from outside world and executed in an offline environment. It consist of the following components:

  • A server rack containing:
    • A computer running a browser-based graphical user interface for accessing Test Catalogs and controlling the Test Execution System
    • A physical IO controller for Object Controller IO connectivity (using Ilme connectors) and optional Test Adapter connectivity
    • Two Ethernet interfaces for two RaSTA channels
  • Display, keyboard and mouse to operate the browser-based graphical user interface
  • Requires 4m² of space and a table
  • Power supply: 230 V AC
RTC-IO Online

RTC-IO Online allows portable EULYNX testing anywhere with minimum overhead and maximum convenience. RTC-IO Online comes in a case with Ethernet interfaces for RaSTA connectivity and a physical IO controller for field element emulation.

RTC-IO Online automatically connects to a cloud instance of Relesoft Test Center during boot. It supports a data SIM card and a WAN Ethernet port for online connectivity. The cloud instance of Relesoft Test Center is accessed over the Internet, directly with your laptop and web browser. Relesoft Test Center controls the RaSTA Ethernet interfaces and the physical IO controller to execute test cases through RTC-IO Online.

RTC-IO Online is connected to a SCI-P EULYNX field element Subsystem (object controller). The blue RJ45 connects to a RaSTA channel (two available) and the gray IO connectors are for field element emulator running a point emulation.
