3-8-2 Using the Buzzer
The NT620S/620C can set a buzzer to indicate the occurrence of an emergency
or an NT620S/620C error.
Setting the Buzzer
Except when the buzzer has been set so as not to sound at all, the buzzer will
sound when an error occurs. To set the buzzer to sound in other cases, the fol-
lowing two procedures can be used.
S
Controlled by the host
It is possible to control the NT620S/620C from the host to sound the buzzer
during the operation.
Refer to Section 5-7 “NT620S/620C Status Control” (page 234).
S
Set the buzzer as a screen data attribute by using the support tool.
When creating the screen data by using the support tool, set the buzzer as a
screen attribute so that the buzzer will sound. When the screen in which this
attribute has been set is displayed, the NT620S/620C will give the buzzer
sound.
If the control by the PC and the display of the screen in which the buzzer attribute
has been set are executed simultaneously, the priority is given to the control by
the PC. Refer to the NT-series Support Tool Operation Manual (V028-E1-
j
).
To Stop the Buzzer Sound
The buzzer sound can be stopped by the following operation.
S
Control by the host
S
Switch the screen to a screen which does not have a buzzer attribute.
S
Press the touch switch to which the buzzer stop attribute has been set.
If a buzzer stop attribute has been set to a touch switch created on the screen in
which the buzzer attribute has been set, such touch switch can be used to stop
the buzzer sound.
To set a buzzer stop attribute for a touch switch, set the
control key function
for the touch switch by using the input key function.
For the touch switch setting, refer to Section 4-7 “Touch Switches” (page 151).
Types of the Buzzer Sounds The following buzzer sounds can be set.
S
Continuous sound:
The buzzer continues to sound.
S
Short intermittent sound:
The buzzer sounds intermittently at 0.5 second
intervals.
S
Long intermittent sound:
The buzzer sounds intermittently at 1 second
intervals.
If two or more buzzer sound specifications are made from the host at the same
time, the order of priority that determines which buzzer sound will be used is as
follows: (1) continuous sound
→
(2) short intermittent sound
→
(3) long intermit-
tent sound. If the continuous sound and short intermittent sound are specified at
the same time, the continuous sound takes priority.
Setting the Buzzer
Use the memory switches to set whether or not the buzzer sounds when the
buzzer sound has been instructed by the PC or with a screen attribute or when an
error has occurred.
The factory setting is not fixed.
