Description

EULYNX test and simulation system for object controller and interlocking testing and verification

Relesoft Test Center (RTC) is an ISO/IEC 17025 and Eu.Proc.7 – 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.

The system enables manufacturers to increase development speed and decrease cost by detecting EULYNX compliance issues early. On other hand infrastructure managers can benefit from the system on national or project-specific testing of EULYNX compliance.

Designed and implemented by leading European EULYNX and testing experts, Relesoft Test Center supports testing multiple protocols and multiple delivery variants. The system has an easy-to-use, web-based user interface. Test database includes all official EULYNX Baseline 4 test catalogs from the EULYNX Consortium Office.

Feature highlights

All EULYNX Interfaces and Versions Are Supported

• Testing supports all baselines and releases of EULYNX
• Testing supports all SCI interfaces over RaSTA (UDP / TCP+TLS)
• SCI Generic (PDI) and all EfeS interfaces can be tested with official EULYNX test case definitions (SCI-P, SCI-IO, SCI-LS, SCI-TDS, SCI-LC, SCI-LX)
• Custom test coverage can be specified, implemented and performed for SCI-CC, SCI-ILS and SCI-RBC
• Testing supports SDI and SMI over OPC UA
• Test bench includes Shared Cybersecurity Services for SSI

Shared Cybersecurity Services for SSI

• Shared Cybersecurity Services available for SSI in test bench network (NTS (SCS-STS), PKI RA/CA (SCS-PKI/ESS-PKI), …)
• Syslog over TLS server (SCS-LOG) available to collect safety-related log messages with SSI-LOG Security Logging and to relay the syslog messages into a SIEM system for collection and analysis

Advanced Test Execution

• Test Execution System supports many types of executable test steps. Has been used for example for FAT and pre-SIT testing for EULYNX systems.
• Hardened execution logic to eliminate false positive and false negative results.

Field Element Emulation

• Programmable field element emulator logic (e.g., to write a point machine emulator for SCI-P testing)
• Execute field element emulators with a Device Emulation Interface component, which controls a physical, integrated IO controller for wired connectivity with the system under test.

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
• Comprehensive and detailed test report generator

Multiprotocol testing use case

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)

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 including verification of legal route setting with respect to the field element emulator states.

Has a reference for replicating large traffic locations as needed in interlocking commissioning and SAT testing. Additional information available at https://www.linkedin.com/pulse/how-rtc-infrastructure-simulator-transformed-eulynx-based-rmxkf

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 the outside world and executed in an offline environment.

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.
