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.
