7.1.2.4 Scaling

This function is used to scale the position setpoint, i.e., to influence the input signal's value range. The output
signal is derived from an offset and the multiplication of the input signal with a factor (sets the signal's slope)
according to the following function:
ValvePositionControl_DemandValueGenerator_Scaling
Index Subindex Name
0x6322 0 Factor
0x6323 1 Offset
0x6323 2 Unit
0x6323 3 Prefix
Chapter "1.6.2 Definition of unit and prefix", page 5
<Factor>
Factor by which the input is multiplied. It is calculated from a numerator (upper 16 bits of the parameter) and a
denominator (lower 16 bits of the parameter).
Bit
Meaning
The default value 0x00010001 corresponds to the factor 1.
<Offset>
The offset is added to the scaled input value.
