To edit the variable, highlight the variable placeholder in the

Click the Embedded Variable tool.

Or select the Edit Variable command on the Format menu.
When a variable is created or edited, its dialog appears:
Format
The Field Width spin control specifies the maximum number of
characters (0 to 9, +, -, and .) that can be entered in the variable.
Default is 12. To change the field width, select or enter a value in the
spin control.
Decimal Point
A logic controller can store only integer values. If the entered value
is a decimal, it will be rounded by the logic controller. However if
the value is scaled, it may be entered as a decimal, but stored as an
integer. See the section on entry scaling beginning on Page 4–38.
The Decimal Point area specifies whether the decimal point is fixed
(formatted), or keypad controlled.
•
Select Fixed to position the decimal point 0 to 4 places to the left
of the rightmost character. As the terminal operator enters the
value the numbers are shifted to the left around the decimal point.
Select or enter a value in the Position spin control. The decimal
position must be less than the field width.
