Note:
Priority registration is only effective when NT
link (1:N) is set.
The PC status control bits remain unchanged if the NT620S/620C status is
changed with the screen attributes or memory switches, which means that the
statuses of the PT status control bits do not match the actual status of the
NT620S/620C. For example, the buzzer may sound even though the setting for
continuous buzzer bit 13 is “OFF”.
In this kind of case, control the NT620S/620C by using the PT status control bits.
S
Screen display (bit 15)
The screen display bit is used to display and clear the screen to prevent “burn-
in” on the CRT. Set bit 15 to 0 (OFF) to clear the screen. In the case of the
NT620C, the backlight also goes off at the same time.
When the screen has been cleared, the last displayed screen can be redis-
played either by turning Bit 15 ON, or by pressing a touch switch. The backlight
also comes back on.
Reference
- Instead of turning Bit 15 ON, a screen can be displayed by specifying its
screen number. For details on screen switching, see “Switching the Screen
Display” (page 191).
- If a screen disappears while bit 15 is ON, switch bit 15 OFF and then back ON
again.
S
Priority registration for processing (NT link 1:N connections only) (bit 14)
It is possible to register one of the multiple PTs connected by the 1:N NT link
method to have processing priority. The PT for which bit 14 is set ON (1) is
given priority over the other PTs and has a higher response speed for display,
