Screen Display Section 4-3
4-3-2 Screen Attributes
Each screen can be set with a specific function by designating a screen attribute,
so that the specific function can be executed by displaying the screen. For exam-
ple, by displaying a screen to which a “buzzer attribute” has been set, the buzzer of
the NT20S starts sounding.
Set the screen attributes for each screen on the “screen selection” screen of the
support tool.
Note that the support tool displays some items that are not used with the NT20S,
such as “history attribute”, “alarm”, and “backlight color”.
The following several attributes can be set with one screen.
Buzzer Attribute This attribute will become effective to sound the buzzer in the NT20S when the
screen to which this attribute has been set is displayed. The buzzer sound can be
set as follows:
No: Buzzer does not sound when the screen is displayed.
Continuous sound: Buzzer sounds continuously.
Intermittent sound: Buzzer sounds intermittently at constant intervals.
The buzzer sound is set with the NT20S memory switch. The buzzer can also be
set by using the Host. Refer to “Using the buzzer” (page 92) for the buzzer setting
using the memory switch.
To stop the buzzer by using the screen operation, create a system key as a
touch switch.
Numeral Setting Attribute Select whether the numeric keys are automatically displayed or the numeric keys
are created at arbitrary positions on the numeral setting screen. The following two
numeral setting attributes are used.
System: The numeric keys registered to the system are automatically dis-
played.
User: The numeric keys can be created at any arbitrary positions.
Reference: If the numeral setting attribute on the NT20S has been set for “system”, the touch
switches [ENT], and which are allocated to the system besides the numeric
keys need to be created. (System key functions (page 139))

when the touch switch is pressed. There are two types of bit input attribute in the

the touch switch is notified using its number.
