To sound the buzzer during the operation of the PT, operate the PT status control
area as indicated below.
Set 1 (ON) for the following bit in the fourth word (n + 3 words) from the beginning
of the PT status control area according to the required buzzer sound.
• Continuous sound:
• Short intermittent sound:
• Long intermittent sound:
With the PT, 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 dur-
ing operation of the PT, the buzzer automatically stops sounding. For the proce-
dure for switching the screen, refer to 3-3-1 Switching the Screen (page 289).
