Summary:Software-in-the-loop (SIL) is a common methodology for repeatable and controllable component testing during the development process of complex systems. Testing the integration of distributed embedded systems is accomplished on a network centric abstraction level. However, todays state-of-the-art is missing a solution for the railway domain which couples local simulations via the Internet or LANs to support those tests between companies. The framework proposed in this paper is based on the simulation standards FMI (Functional Mock-up Interface) and HLA (High Level Architecture). They are combined with further mechanisms for configuration, delay-management, fault-injection, monitoring and simulation control. This solution enables SIL testing via the Internet without sharing any software. Hence, it facilitates the interplay between different railway manufacturers and allows early integration tests wherefore testing effort and time can be reduced compared to today.
