A Fault Injection based Approach for Safety Industrial Control Applications

This paper deals with an optimized simulation of industrial control applications following the component-based standard IEC 61499. According to this standard, a Function Block (FB) is an event triggered component and an application is a network of distributed blocks. We design these components in different abstraction levels to reduce the development complexity. To optimize the simulation, we define critical scenarios presenting application executions with high probabilities to fall into faults. To bring the application into such scenarios, we propose to apply a simulation based on a fault injection technique. By considering the application modularity, we exploit the master-slave model to implement the simulator. The master defines errors allowing to bring the application into critical scenarios, whereas each slave injects these errors in the behavior of blocks belonging to a particular abstraction level
