127 Scrolling Lists
Publication 2711E-820 – January 1998
Field Meaning
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.
After you configure the Numeric Data Display Object List and any
other object lists that are part of the same Scrolling List, group the
object lists with the Cursor List. You must group all the components
of the Scrolling List at the same time or PanelBuilder will report a
validation error. For more information about grouping objects see
Chapter 9, Creating Objects, in the PanelBuilder 1400e
Configuration Software for Windows User Manual.
For an example of how to configure Numeric Data Display Object
Lists that would be displayed with your Cursor List, see “Scrolling
List Example” at the end of this chapter.
