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.
