Detailed Description
The EdgeTriggerOperator triggers default output value on rising and/or falling edge(s).
An EdgeTriggerOperator triggers its output value for one process period if the edge of the default input is greater or equal to threshold.
Properties and Arguments
| Name | Description |
|---|---|
| Edge | Specifies the edge on which the signal is triggered. |
| In | The default input value. |
| Out | The default output value. |
| Threshold | Specifies the threshold on which the signal is triggered. |
When operator is used inside a signal its default input is automatically tied to signal's InternalValue or previous operator's output. Its default output is automatically tied to next operator's input or to signal's Value. See also CDP Operator Usage In CDP Signals.
Actual Processing Code of the EdgeTriggerOperator
unsigned int EdgeTriggerOperator<T>::Process() { if (!d->threshold) return STATUS_ERROR; bool risingEdgeDetected = d->DetectRisingEdge(); bool fallingEdgeDetected = d->DetectFallingEdge(); m_output = (d->TestEdgeFlag(eRisingEdge) && risingEdgeDetected) || (d->TestEdgeFlag(eFallingEdge) && fallingEdgeDetected); return STATUS_OK; }
See also Argument.
Member Type Documentation
enum EdgeTriggerOperator::Edge
This enum specifies the edge of a input value to detect.
| Constant | Value | Description |
|---|---|---|
Automation::EdgeTriggerOperator::eRisingEdge | 0x01 | Rising edge of the input value. |
Automation::EdgeTriggerOperator::eFallingEdge | 0x02 | Falling edge of the input value. |
Automation::EdgeTriggerOperator::eRisingAndFallingEdge | eRisingEdge | eFallingEdge | Rising and falling edge of input value. |
Member Function Documentation
EdgeTriggerOperator::EdgeTriggerOperator(const CDPPropertyBase &in)
Constructs an EdgeTriggerOperator with input in.
[virtual] EdgeTriggerOperator::~EdgeTriggerOperator()
Destructs the instance.
[override virtual] void EdgeTriggerOperator::Configure(XMLPrimitive *pObjectXML)
Reimplemented from CDPBaseObject::Configure().
[override virtual] void EdgeTriggerOperator::Create(const char *shortName, CDPBaseObject *parent)
Reimplemented from CDPBaseObject::Create().
Edge EdgeTriggerOperator::GetEdge() const
Returns the edge on which the signal is triggered.
T EdgeTriggerOperator::GetThreshold() const
Returns the threshold on which the signal is triggered.
[override virtual] unsigned int EdgeTriggerOperator::Process()
Reimplemented from CDPOperatorBase::Process().
Returns STATUS_OK.
void EdgeTriggerOperator::SetEdge(Edge edge)
Sets the edge on which the signal is triggered.
void EdgeTriggerOperator::SetThreshold(T threshold)
Sets the threshold on which the signal is triggered. The threshold argument must be positive, otherwise calling this function has no effect. If the threshold argument is equal to 0 then the signal is triggered on every change.
