on the setting block to perform the modification. The user could
also modify Type, Scale Ratio, Offset and Deadband on this
interface. The Scale Ratio setting and Offset setting allows user
to transform the Input Register value in this block by linear
transformation. The formula is as follow:
Transformed Value = Scale Ratio x Input Register value +
Offset
After the linear transformation, the Transformed Value will be
saved in floating point format on the PMC/PMD(no matter what
format the raw Input Register value was in the device). The
default Scale Ratio will be 1 and the default Offset is 0,
indicating not using linear transformation.
