BrowseName	Description
<DefectReason>	The defect reasons triggered by the sensor function.
DetectionMode	When DetectionMode is True, the sensor function measures the sensor value and the inner defect reasons are enabled, meaning they can be active or not. When DetectionMode is False, the inner defect reasons are also not active.
SensorValue	The value measured for the sensor function.
UIInfo	The visualization resources to display the SensorFunctionType on the User Interface.

The Method LoadReferenceFeatures loads binary profiles to be used as references for defect detection.

The signature of this Method is specified below. Table 60 specifies the Arguments representation.

Signature

	LoadReferenceFeatures (
	  [in]  0:ByteString[]     				Features,
	  [out] MethodExecutionFeedbackType		ExecutionFeedback);

Table 60 – LoadReferenceFeatures Method Arguments

Argument	Description
Features	The list of binary profiles used as references for a detection system.
ExecutionFeedback	The extended feedback returning a detailed message in case of execution failure.

The Method SetDetectionMode enables or disables the defect detection sensor.

The signature of this Method is specified below. Table 61 specifies the Arguments representation.

Signature

	SetDetectionMode (
	  [in]  0:Boolean     					Enable,
	  [out] MethodExecutionFeedbackType		ExecutionFeedback);

Table 61 – SetDetectionMode Method Arguments

Argument	Description
Enable	Specifies if the method enables, when True, or disables, when False, the sensor function.
ExecutionFeedback	The extended feedback returning a detailed message in case of execution failure.

The Method SetDetectionMode sets the DetectionMode of the sensor function and of its components, i.e. the defect reasons.
