3.2.97 SUB_ - Subtraction
SUB_ function blocks perform arithmetic subtraction on
the two input signals. Any unused input will be set to 0.0.
All inputs should have the same engineering units. If units
are not consistent, a SCL function block can be used or an
alternative is to use a MTH function block that has built-in
scaling functions.
