To edit the variable, highlight the variable placeholder in the
message.

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.
