Decimal Point
A value may be stored as an integer, then scaled by the terminal so it
can be displayed as a decimal. See page 12–2 on scaling.
The Decimal Point area specifies whether a scaled value displays
with a fixed or floating point decimal.
32767 x (.0001) +94 =
SCALE
Scale = .0001
Offset = 94
Terminal Value=32767
Displayed Value=97.2767
•
Select Fixed Point to position the decimal point 0 to 10 places to
the left of the rightmost character. A value of 0 displays a value
without a decimal point.

Note: If Position is
0, then the field width must be 2 > decimal
position for positive numbers. One position is used for the digit to
the left of the decimal and one for the decimal point. For negative
numbers the field width must be 3 > decimal position.
For example, to display the number –0.1234, set the field width to
7 and the decimal position to 4.

Select Floating Point to have the terminal position the decimal.
