internal counter for button press duration

Warnings

Safety Warnings for GlobalVar press_cnt.
Safety warnings are related to the Requirements Layer, especially the SIL

press_cnt has a SIL required of SIL_1 but a SIL achieved of QM

Required
The highest SIL derived from SafetyRequirements and the parent SoftwareUnit. SIL derived	SIL_1
This attribute allows to overwrite the derived SIL level. The result is the SIL effective attribute. SIL manual	derived
The reason why the derived SIL is ignored and an explicit SIL is set. reason
The SIL required for this implementation unit is defined by the derived SIL but can be overwritten by "SIL manual". SIL required	SIL_1
Achieved
The achieved SIL for this implementation unit. Has to be provided by the user. SIL achieved	QM
A justification why a certain SIL was achieved. justification
