134 Scrolling Lists
Publication 2711E-6.15 – November 1998
Configuring the Cursor List Font
You can apply most of the font sizes in the Format menu to the
Cursor List; the only fonts you cannot use for Cursor Lists are the
Very Tiny, Tiny, and Extra Large. The font height you choose
determines the size of the list. A Large or Double High font doubles
the vertical size of the list, reducing the number of entries by half. If
the font is Large or Double High, the maximum number of visible
states is 12. If not, it is 24.
Note: All Object Lists should have the same font height as the
Cursor List. If screen space is limited, use a smaller font.
Optimizing Scrolling List Performance
The Scrolling List object operates faster in Remote I/O applications
than in DH+ and ControlNet applications. If your application is
configured for DH+ or ControlNet, the following tips will help
maximize performance:
•
The Scrolling List performs faster if Visible State write tags are
not used. If Visible State tags are used, assign as few visible states
as possible.
•
If there are several visible states, use the Top Position to PLC and
Cursor Indicator to PLC controls, and keep control values for the
list at the PLC instead of with the Cursor List Object.
•
Use a low auto-repeat rate, because the Scrolling List repeats one
at a time only. How fast it can repeat depends on the DH+ or
ControlNet network traffic.
You can adjust the size of each component of the Cursor List and
format the object’s foreground color, background color, font style,
button margins (touch screen applications only), border style, fill
style, and blink attributes. You cannot use the Extra Large Font for
the Cursor List or its object lists. For details on formatting objects
see “Changing Object Appearance” in Chapter 9, Creating Objects,
in the PanelBuilder 1400e Configuration Software for Windows User
Manual.
