1. Continuous buzzer
2. Short intermittent buzzer
3. Long intermittent buzzer
When stopping the buzzer by PT status control bit operation, set all three of the
bits above to 0 (OFF).
- The buzzer will actually sound only when the "Buzzer Sound" memory switch of
the NT631/NT631C is set to "ON".
- The buzzer can also be stopped in other ways: by using a touch switch to which
the buzzer stop attribute has been assigned (page 469), or by setting the screen
attribute that stops the buzzer sound (page 252).
- The buzzer can also be controlled by using the "Buzzer" screen attributes (page
252).
- Display history initialization (bit 11)
This bit is used to initialize the display history recorded in the NT631/NT631C.
When it is switched from 0 (OFF) to 1 (ON), the display history in the
NT631/NT631C is initialized.
After initialization, return its status to "0".
The display history can also be initialized from the "MEMORY INIT. MENU" screen
under the System Menu of the NT631/NT631C.
- Backlight mode (bit 8) (NT631C only)
The backlight mode is used for controlling the backlight of the NT631.
This function is not available with the NT631.
The status of bit 8 has the following effects.
- 1 (ON): lit
- 0 (OFF): flashing
- Screen printing (bit 7)
Hard copies of the screen can be made by connecting a printer to the
NT631/NT631C.
When bit 7 is set from "0" (OFF) to "1" (ON), printing of the currently displayed
screen starts. Note that it is not possible to stop printing while printing is in
progress.
Check that bit 7 (printer operating status) of the PT status notify area is in the
"0" (OFF) status before starting printing.
When printing starts and bit 7 has been set to the "1" (ON) status, return the
"screen printing" bit to "0" (OFF).
- It is also possible to print screens by using a touch switch assigned the "Print
screen" function.
- The printer type (control protocol) and printing method, are set with the memory
switches of the NT631/NT631C.
