Scale and measurement unit - two-byte field. The most significant byte stores scale as an exponential factor (-128..127), while the least significant byte stores the measurement unit code. Import utility can define the scale and output the measurement unit. In execution state this parameter is not accessed (the scale is stored in tag settings).
