Detailed Description
The NEOperator is a greater than or equal, or NE comparison function block as referenced by IEC 61131-3 in PLC.
The NEOperator output (Out) is set to true when the first argument (In1) does not equal with the second argument (In2), otherwise it will be set to false.
Arguments
| Name | Description |
|---|---|
| In1 | Argument 1 |
| In2 | Argument 2 |
| Out | Result of the logical operation |
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 NEOperator
unsigned int NEOperator<T>::Process() { if (!m_in2) return STATUS_ERROR; m_output = (T)*m_in1 != (T)*m_in2; return STATUS_OK; }
