UC10 - Safe function out of Context

Safe function out of context
UC10
Railway

This use case corresponds to safety-critical systems subjugated to various safety standards in the railway domain. The use case is defined by ALSTOM. A typical application in the railway domain receives a frame of (sensor) data, perform the intended safe/non-safe function, and then responds in a predetermined time frame that is typical to the application domain. If something happens with the function or it is not executed within the right time frame, the error should be detected and handled by the system in a domain-specific response time. A typical scenario is a fault-detection of the motor control in the application. When detected, the application should come to a complete stop and the status reported to the surveillance system.
