Safety-Requirement - SafetyRequirement_98

Multiple System-States

uRTE allows the definition of multiple system-states where each state has an own data-flow.
For each runnable the system state it shall be active in is configured.
The resulting data-flow can be visualized in Software Model/uRTE/SystemStates

Testing Warnings for SafetyRequirement Multiple System-States
Testing warnings are related to the tests in the testing layer and their depedencies.

(SafetyRequirement_98) Multiple System-States is not referencing a test but all refinements reference a test.

(Requirement_95) UART

When the button is pressed, the system-state shall change from Blink into UART mode.
The start of UART mode shall be signaled via UART.
As long as the button is pressed, UART strings with the time in seconds the Button was pressed shall be send with the frequency with which the button pressed signal is updated.
