Safety

Required
The highest SIL derived from SafetyRequirements and Technical Functions. SIL derived	-
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	-
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
