Detailed Description
The NormalPositionOperator inverts signal value based in NormalPosition value.
A NormalPositionOperator sets output value equal to inverse of input value if NormalPosition is set to Normally Closed (1) and output value equal to input value if NormalPosition is set to Normally Open (0). NB! NormalPositionOperator is implemented for boolean signals only!
Properties
| Property Name | Description |
|---|---|
| NormalPosition | Specifies whether Normal Position is Normally Open (0) or Normally Closed (1). |
Arguments
| Name | Description |
|---|---|
| Out | The default output value. |
| In | The default input value. |
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 NormalPositionOperator
unsigned int NormalPositionOperator<bool>::Process() { if(d->normalPos) //normally closed m_output = !m_input; //invert else //normally open m_output = static_cast<bool>(m_input); // do nothing, just pass through return STATUS_OK; }
