16 bit signed integer equals the value multiplied by 10
(bit 15= sign)
Remark:
1. In case the requested value is out of the unit set
point range and/or the user interface set point range,
the set point is set to the minimum limit value or higher
limit value.
2. For the result please check for the value in the input
