Safety-Requirement - SafetyRequirement_97

local and global signals

Signals can either be global data objects of local objects on the task stack.
Global signals are the same for everyone while with local signals each task has an own copy which gets synchroized if the signal changes,

Warnings

Testing Warnings (1)

Testing Warnings for SafetyRequirement local and global signals
Testing warnings are related to the tests in the testing layer and their depedencies.

(SafetyRequirement_97) local and global signals 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.
