5-7 Section NT620S/620C Status Control
237
Another way to stop a buzzer sounding is to use a touch switch to which the
buzzer stop attribute function is allocated.
Whether or not the buzzer actually sounds also depends on the setting of the
“buzzer” memory switch of the NT620S/620C. For details on this setting, see
“Using the buzzer” (page 83).
In addition to PT status bit operations, the buzzer status can also be controlled
by using screen attributes. The screen attributes are set with the support tool.
Buzzer attribute: Set whether the screen will sound or not when a screen is
displayed, and, if it sounds, the type of buzzer.
S
Display history initialization (bit 11)
“Display history initialization” initializes the display history in the
NT620S/620C.
When bit 11 is switched from “0” (OFF) to “1” (ON), the display history in the
NT620S/620C is initialized.
After initialization, it returns to the “0” (OFF) status.
S
Screen printing (bit 7)
Hard copies of the screen can be made by connecting a printer to the
NT620S/620C.
When bit 7 is set from “0” (OFF) to “1” (ON), printing of the screen displayed at
that time starts. Note that it is not possible to stop printing part way through.
Start printing after confirming that bit 7 (printer operating status) of the PT sta-
tus notification area is in the “0” (OFF) status.
When printing starts and bit 7 of the PT status notification area has been set to
the “1” (ON) status, the “screen printing” bit is returned to “0” (OFF).
S
Window opening (bit 6)
It is possible to display a partial screen overlying the currently displayed
screen. This partial screen is called a “window”, and control of windows can be
allocated to touch switches. “Window opening” is specified to disable the
opening of windows using touch switches.
When bit 6 is set to “1” (ON), windows will not open even if a window opening
touch switch is pressed, and currently open windows are closed.
S
Numeral/character-string input (bit 5)
This bit makes it possible to disable the input and thumb wheel type input of
numerical values and character-strings into numeral/character-string input
fields.
When bit 5 is set to “1” (ON), it will not be possible to input anything into input
fields by pressing touch switches to which numeric keys and character-string
keys are allocated. It will also not be possible to change numerals using thumb
wheel type input.
