Detailed Description
The GTOperator is a greater than, or GT comparison function block as referenced by IEC 61131-3 in PLC.
The GTOperator output (Out) is set to true when the first argument (In1) is greater than 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 GTOperator
unsigned int GTOperator<T>::Process() { if (!m_in2) return STATUS_ERROR; m_output = (T)*m_in1 > (T)*m_in2; return STATUS_OK; }
