The SUB (-) instruction subtracts subtrahend In2 from minuend In1 and outputs the result to output
value Out.
In1 and In2 can have different data types. However, use the combination that data types to include are
existed. If they are different, calculations are performed with the data type that includes the range of all
of the data types. For example, if In1 is INT data and In2 is DINT data, calculations are performed with
DINT data. Here, the subtraction result is DINT data.
