Field Meaning
Decimal Display How you configure the decimal display and polarity determines
the appearance and behavior of the Numeric Data Display. It
also determines the controls you must assign. Each Numeric
Data Display Object List can have only one configuration.
Disabled—Check this button if you don’t want a decimal point
displayed. If the Visible State value contains a decimal point, it
is rounded off.
Implicit—The value from the Visible State control is displayed
as it is, without any external decimal position manipulation. For
example, a value of “1” is displayed as “1” and 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
shows “1.24”. If an integer value or the integer portion of a
number can’t be displayed fully, asterisks (***) are displayed.
PLC Controlled—Check this box 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
numbe o i it a te the ecimal oint.
number of digits after the decimal point.
Generally, use this option with integer values so the decimal
point is only implied. If the value is an integer value, the decimal
point is displayed within the number string.
If the Visible State value is a fractional number and has fewer
than the specified number of digits, the value is padded with
zeros. If the value has more than the number of digits, the value
is rounded off.
If you check this button, define the Decimal Point Position
control.
Fixed Position—Check this box if you want the decimal point
to always appear in a certain position. Specify the number of
digits to appear after the decimal point. Enter a value between 0
and 15. The maximum number you can enter is the Number of
Digits (above) less 1.
Tip: Use Fixed Position with a tag that has scale and offset
defined to achieve the version 5.10 Scaled Numeric Data
Display capability, or define an expression to achieve the same
effect.
Digits after Decimal
Point If you specify the decimal point as Fixed Position, enter the
number of digits that will appear after the decimal point, up to
15. The maximum is the Number of Digits (above) less 1.
