Stopping the Buzzer by the Operation at the PT Control Area
[Setting]
To sound the buzzer during the operation of the NT31/NT31C, operate the PT sta-
tus control area as indicated below.
(1) Set "1" (ON) for the following bit in the fourth word (n + 3 words) from the be-
ginning of the PT status control area according to the required buzzer sound.
- Continuous sound:
- Short intermittent sound: Bit 12
- Long intermittent sound:
With the NT31/NT31C, the following three methods are used for stopping the
buzzer sound.
- Displaying a screen for which the buzzer attribute is not set
- Operating the PT status control area
- Pressing a touch switch which has the "buzzer stop" function
When this method is used, the buzzer stops sounding automatically when the
screen is switched to the one where the buzzer attribute is not set.
When creating a screen using the Support Tool, cancel the check mark for the
buzzer attribute at the screens where the buzzer should not sound. (Usually, the
buzzer attribute is not checked.)
When the screen for which the buzzer attribute is not checked is displayed during
operation of the NT31/NT31C, the buzzer automatically stops sounding. For the
procedure for switching the screen, refer to 8-3-1 "Switching the Screen" (page
480).
This method allows the operator to stop the buzzer at any required time.
Stopping the buzzer
The PT status control area must be allocated to a word in the host and, according-
ly, there are no special settings required for the control of buzzer.
