Detailed Description

The LEOperator is a greater than or equal, or LE comparison function block as referenced by IEC 61131-3 in PLC.

The LEOperator output (Out) is set to true when the first argument (In1) is less than or equal with the second argument (In2), otherwise it will be set to false.

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.

Arguments

Actual Processing Code of the LEOperator

unsigned int LEOperator<T>::Process()
{
  if (!m_in2)
    return STATUS_ERROR;

  m_output = (T)*m_in1 <= (T)*m_in2;

  return STATUS_OK;
}
