Configuring the Numeric Data Display
Configure the Numeric Data Display according to the following
table:
Field Meaning
Name Assign a name, up to 15 characters, to document the object for
printed reports. This increases the application’s size by 1 byte
per character.
Fill Left With Choose whether the left portion of the display will be filled with
zeroes or blank spaces when fewer than the maximum number
of digits are displayed.
Number of Digits Specify the number of digits to display, up to a maximum of 16.
Keep in mind that a decimal point and minus sign each take one
digit.
At runtime, if the value cannot be displayed within the number
of digits specified for the object, a string of asterisks (*) is
displayed.
Decimal Display How you configure the decimal display and polarity determines
the appearance and behavior of the Numeric Data Display. (See
the examples before this table.) The configuration also
determines the tags or expressions you must assign. Each
Numeric Data Display can have only one configuration.
Disabled—Select this item if you do not want any decimal point
displayed. If the Displayed Value control contains a decimal
point, it will be rounded off.
Implicit—The value from the Displayed Value control will be
displayed as it is, without any external decimal manipulation.
For example, a value of “1” is displayed as “1”. A value of “1.3”
is displayed as “1.3.” If the number of digits following the
decimal point is too large to fit in the display, the fraction is
rounded off to fit the number of digits. For example, if the
display has four digits, and the value is “1.237,” the display will
show “1.24.” If an integer value or the integer portion of a
number can’t be displayed fully, asterisks (***) are displayed
instead.
PLC Controlled—Select this item if you want the position of the
decimal point to be determined by the PLC. This means that the
decimal point is not in a fixed position, and the PLC controls the
number of digits after the decimal point. If the Displayed Value
control is a fractional number and has fewer than the specified
number of digits to the right of the decimal point, the value will
be padded with zeroes. If the value has more than the number
of digits, the value will be rounded off. The PLC Controlled
decimal position can display 1 to 15 decimal digits. If the value
returned by the Decimal Point Position control is outside this
range, the display field is filled with asterisks (***). If you check
this button, define the Decimal Point Position control.
