Section 7-1
The setting for the “Buzzer Sound” memory switch at the NT31/NT31C takes
priority in determining whether or not the buzzer actually sounds. When this
memory switch is set to “ON”, the buzzer set with a screen attribute can sound.
Reference - The buzzer can also sound by PT status control bit operation (page 470).
- The following methods can be used to stop the buzzer when it is sounding.
@ Switching to a screen whose buzzer attribute is “None”
@ Stopping the buzzer by PT status control bit operation (page 471)
@ Registering the “buzzer stop” touch switch on the screen (page 472)
S Background color (NT31C only)
With the NT31C, the background color of the entire screen can be set for each
screen. The following 8 background colors can be set.
Black, blue, red, magenta, green, cyan, yellow, white
S Screen comment
A comment indicating the contents of the screen can be set as any required
character string of up to 24 characters.
S History
When a screen for which this attribute is set is displayed, the screen number,
display time, number of times displayed, and history title of the displayed screen
are recorded as display history data.
Setting Function

Reference: The display history can be checked in the Maintenance mode of the NT31/NT31C,
and can also be read during operation by displaying screen number 9001 (occur-
rence order) or screen number 9002 (frequency order). It is also possible to trans-
mit the display history record data to the personal computer by operation at the
Support Tool. For details, refer to NT-series Support Tool Ver. 3.0 for Win-
dows95/98 Operation Manual, 11-5 “Receiving (Uploading) the History Record”.
S History title
This attribute sets a character string to be recorded in the display history along
with the display time and other information when a screen for which the “history”
attribute is set is displayed.
The history title can be set as any required character string of up to 24 charac-
ters.
This setting is only valid for screens for which the “history” attribute is set. When
a screen for which the “history title” attribute is set is displayed by the
NT31/NT31C, the designated character string is recorded together with the
screen number in the display history.
