HighRange - Defines the desired upper range of the resulting scaled value.
LowRange - Defines the desired lower range of the resulting scaled value.
Clamping - Set to true to insure that the value does not go outside this
range and that any value written to the source tag does not go outside of the defined raw range.
SquareRootScaling - Set to true to select square root scaling instead
of the default linear method.
Masking - Set this to true to begin masking. You can enter a mask that
will be applied to the integral source tag when the data sample arrives at the Process Tag. Masking is ignored if
the source tag is not an integral type.
Mask - The bits set in the mask indicate the bits used (AND'ed). The value will be
shifted to the proper weight. Masking is applied on reads and in reverse on writes. Use any radix format such as
16#00ff,fff0 or any decimal number like
