• Consecutive screens
The screen type is set for each screen in the Screen List Screen of the NT-series
Support Tool. Select the screen type according to the purpose, and create char-
acters and figures on the screen. Details on each screen type are given below.
A normal screen is the basic screen of the NT30/30C. It is not necessary to select
a screen type (overlapping or consecutive) to create screen data for a normal
screen. When a normal screen is selected, the display of existing screens will be
stopped and the normal screen will be displayed.
Several screens can be overlapped and displayed as one screen. A group of
overlapped screens is called overlapping screens.
Several screens are displayed in the order of screen numbers to form overlap-
ping screens. Up to eight screens can be overlapped. The base screen used for
making overlapping screens is called the parent screen, and the screens that are
overlapped on the parent screen are called child screens.
With overlapping screens, no display elements are actually created on the patent
screen. Create all display elements on the child screens. Screen attributes, such
as a buzzer attribute, can be set in the parent screen and will be effective in the
overlapping screens.
Example of Overlapping Screens
Screen No. 8
This are
overlapping
screens.
• Parent screen: No. 8
• Child screens: No. 10, No. 7, and No. 25
When the parent screen (No. 8) is designated, screen No. 8 functions as the par-
ent screen and child screens No. 10, No. 7, and No. 25 are displayed overlapping
each other on the parent screen in order.
Only one numeral setting screen or character string setting screen (screens that
allow numeral and character string inputs on the NT30/30C screen) can be regis-
tered as a child screen. For details on numeral settings, see 4-8 Numeral Set-
tings (page 161), and for details on character string settings, see 4-9 Character
String Settings (page 171).
Make sure that touch switches and numbers set in the child screens do not over-
lap when the screens are overlapped. If the set positions of the touch switches
and/or numbers in the child screens overlap with each other on the parent
screen, the settings may sometimes not work as intended. Use the NT-series
Support Tool and make sure that the set positions do not overlap each other.
A group of screens that set up in a specific sequence and can be switched con-
secutively are called consecutive screens. Up to eight screens can be registered
as a group of consecutive screens.
