Safety

Required
The highest SIL derived from SafetyRequirements,Technical Functions and calling Runnables.
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.

Datatype this driver provides/accepts.
DataType
No datatype was defined for this driver. A driver specific type definition was generated.
Defines if the driver provides or applies data synchronously ro asynchronously. Examples: GPIOs are typically synchronous, while communication interfaces are typically asynchrouns.
