Safety

Required
The highest SIL derived from SafetyRequirements.
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.

Properties

Base
The name of this object. Certain classes of objects require this field to be unique. Please consider that this field might be used in code and thus must not contain special characters.
Name 		HWI LED
The type of this object within the uRTE model
Type 		SignalDataObject
A descriptive text for this object. Please consider that this field might be used in code and thus must not contain special characters.
Description

Hardware interface for the LED
A user defined ID which can be freely chosen. Please consider that this field might be used in code and thus must not contain special characters.
User-ID 		SignalDataObject_17
Each object within the uRTE model has a unique ID, this is the ID for this object
UID 		_Qh-JIOTWEeyrV5NXTwe27Q
signal configuration
The minimum age of the signal. If the value is other than 0 then the signal will not be valid if the minimum age is not reached.
miminum Age 		0
The maximum age of the signal. If the value is other than 0 then the signal will not be valid if the maximum age is reached.
maximum Age 		0
Lokal signals are stored in all stacks of all tasks using them, global signals are stored as global data-objects.
Storage (isLocal) 		local signal
if the checksum feature is enabled, the signals content (meta-data and payload) will be protected by a user defined hash alogrithm. The hash is calculated after every write operation to the signal and is checked with every read operation.
Checksum 		false
Depending on how a signal is configured and used, the generator can decide wether an change of the signal shall be signaled by sending a trigger or a deep copy of the signal to the corresponding tasks. If this flag is set, the generator will choose deep copy sychronization over notification where possible.
Force Sync 		false
Determines if the signal code shall be inlined. Might be overwritten by the Signalpool or the SignalLayer
Inline 		false
The inline property might be overwritten by the signalPool or the SignalLayer. This is the effective inline.
effective inline 		false
If this flag is set, an API will be generated with which the signal can be used from an ISR context. This option works along with the global "signal_ISR_API" option.
Has ISR API 		false
The ISR property might be overwritten by the global configuration. This is the effective ISR API status.
effective ISR API 		deactivated for all signals
datasignal configuration
The initial value of the signal. If no value is set, the generator will try to use the inital value of the datatype (if defined).
Initial value: 		0
Will create methods which allow to access the signals payload via a pointer. Meant for signals with large payload or timing critical signals. Use with caution!
Pointer access: 		false
Datatype of the signal payload.
Datatype: 		uRTE_boolean_t
