Digits

The Field Width spin control specifies the maximum number of
characters (0 to 9, +, -, and .) that can appear in the display. If the
value from the logic controller exceeds the specified field width, the
field on the terminal display fills with >>> symbols.

Default is 12. To change the field width, select or enter a value in the
spin control.

To fill empty data positions with zeros rather than leaving them
blank, enable the Fill With Zeros check box. Default is disabled.

Decimal Point

A logic controller can store only integer values, so the value sent to a
display variable is always an integer. However if the value is scaled,
it may be displayed as a decimal. See the section on scaling
beginning on Page 4–37.

The Decimal Point area specifies whether a scaled value displays
with a fixed or floating point decimal.

32767 x (.0001) +94 =

Scale = .0001
Offset = 94

Displayed Value = 97.2767

Select Fixed Point to position the decimal point 0 to 4 places to
the left of the rightmost character. Select or enter the number of
decimal places in the Position spin control. The decimal position
must be less than the field width.
