Select the Scale Values tab to enter up to eight low and high floating
point scale values and one low and high integer values for converting
floating point numbers to a scaled integer.
Figure B-2. Modbus Configuration – Scale Values Tab
Since each I/O point may have different scaling (or calibration), you
use the Integer Scale’s Low Value and High Value fields to normalize
the raw values from the analog I/O points.
The Low Value and High Values fields are signed integers, and can
range from –32768 to 32767. You can also use these data fields to scale
the analog I/O to integer values with an implied decimal point.
For example, all analog I/O raw values can be transmitted with 0 to
1000 values (0 to 100.0, decimal point implied) by entering 0 in the
Low Value field and 1000 in the High Value field. This scaling is used
