Register value
This field is used for saving the 32-bit parameter value.
Parameter values with decimal places are transferred without decimal point. Depending
on the number of decimal places, the values are multiplied by 10, 100 or 1000.
Example: Frequency value
A frequency value of 100.25 Hz is to be transferred. The actually transferred numerical value is 10025,
i.e. 0x2729in the hexadecimal system.
