Start address
This field is used for saving the parameter number and dataset number. The parameter number is in
the range between 0 and 1599 and is saved in the 12 least significant bits. The dataset number is in
the range between 0 and 9 and is saved in the 4 most significant bits.
Example:
Parameter 372 (hex. 0x174), dataset 2 (hex. 0x2) is saved as hex. 0x2174.

Register value
This field is used for saving the 16-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:
A current value of 10.3 A is to be transferred. The actually transferred numerical value is 103, i.e.
0x67 in the hexadecimal system.
