7.4.4 Scaling
This function is used to scale the pressure setpoint, e.g. to influence the input signal's value range. The output
signal is calculated by multiplication of the input signal with a scaling factor and a subsequent addition of an
offset according to the following figure.

7.4.4.1 Object 0x63A2: Factor
This parameter is a slope factor by which the input is multiplied. It is defined by two signed integer values, the
numerator (upper 16 bits of the parameter) and the denominator (lower 16 bits of the parameter).
