Field Meaning
Decimal Display
(continued) 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
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.
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.
Control The Numeric Data Display Object List uses the following
controls. You can assign tags or expressions to these controls.
Decimal Point Position determines the position of the decimal
point. Define this control if you specified the Decimal Display
field as PLC Controlled.
Polarity determines whether or not a minus sign is displayed. If
the Polarity control’s value is other than 0, the minus sign is
always displayed; if it is 0, the sign is never displayed. If this
control is assigned, it overrides the Visible State value’s polarity.
Remember to account for the minus sign in the Number of
Digits you assign.
Visible State controls allow you to attach an individual control
to each visible state in the list.
Important: If you assign the Polarity control, when you create
the Visible State controls use digital or analog tags with any of
the following unsigned data types: byte, binary, bit position, or 1
to 8 BCD. If you use a signed data type, do not assign the
Polarity control unless you want to override the values’ own
polarity.
You can adjust the size of the Numeric Data Display Object List and
format its foreground color, background color, font style, border
style, and blink and underline attributes. You cannot use the Extra
Large Font for the Numeric Data Display Object List. For details on
formatting objects see “Changing Object Appearance” in Chapter 9,
Creating Objects, in the PanelBuilder 1400e Configuration Software
for Windows User Manual.
