Altpro signs contract for ERTMS Protocol Software and STM testing kit

28 September 2018

Convinced by the quality of ERTMS Solutions’ products, ALTPRO  signed a new contract for the implementation and testing of a software laboratory system required for the development of their new STM module, within the industrial research phase of their project.

To do so, Altpro acquired a SW implementation and testing kit, including:

  • FFFIScom/PROFIBUS library
  • Onboard-Monitoring Box
  • Triple-F-Sniffer SW

The FFFIScom Euroradio library provides all the functionality needed to use Euroradio FIS (UNISIG Subset-037) and the Application Layer (Subset 026 chapters 7 and 8) protocols in your own applications.

  • Easy Euroradio Safety/X.224./T.70/HDLC connection management
  • Application layer (Subset 026-7 and 026-8) messages encoding, decoding and validation
  • Euroradio Safety MAC (Message Authentication Code) computation and verification
  • Source code available.

The Onboard Monitoring Box (OMB) is a passive acquisition and monitoring device which collects real-time messages exchanged between various ERTMS OBU sub-systems (such as the EVC, JRU, and STMs) and transfers this information to a configurable application software.

The Triple-F Sniffer software decodes the onboard information and displays the protocols according to ERTMS definitions which allows users to see whether the messages are compatible with ERTMS specifications.

On the top of these activities, Altpro also decided to purchase the Subset-74 Automation Package, to perform an effective and complete testing on their STM from day one.

By using the Triple-F-Sniffer and PROFIBUS/STM recording and decoding software, Altpro will be able to record a unique file for each test case. Within this file, they will have the full PROFIBUS traffic exchange between the FFFIS simulator and the device under test.

The Automation Package not only enables its user to review the exchanged messages after the test and immediately find the cause of test failures, but it can also serve as evidence of Subset-74 conformance.
