Parameters

NameTypeUsageDescription
In_Value1DINTInputFirst value to compare
In_Value2DINTInputSecond value to compare
Out_MaxValueDINTOutputThe greater of the two input values

Behavior

  1. Compare In_Value1 and In_Value2 every scan using standard DINT comparison semantics.
  2. If In_Value1 is greater than or equal to In_Value2, copy In_Value1 to Out_MaxValue.
  3. If In_Value2 is greater than In_Value1, copy In_Value2 to Out_MaxValue.
  4. The AOI must handle equal values, negative values, and full-range DINT inputs.
