 Function Explanation

The instruction is used for the subtraction of two or more variables or constants. The result is output
to Out, that is, Out= In1 - In2.

The input parameters In1 and In2 in this instruction are allowed to be the variables of different data
types among bits, integers and real numbers. When In1 and In2 are the variables of different types,
the subtraction operation will be performed based on the data type which can contain valid ranges of
In1 and In2 values. For example, the data type of Out is DINT if the data type of In1 is INT and In2 is
DINT.
