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. (When the LCD display unit
is used, the backlight will also go OFF at the same time.)
When the screen has been cleared, the last displayed screen can be redisplayed
either by turning Bit 15 ON, or by pressing a touch switch. (When the LCD dis-
play unit is used, The backlight will also light at the same time.)
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 160).
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, touch
switches, etc.
When bit 14 is turned OFF (0), this registration is canceled and the normal re-
sponse speed is reinstated. If priority registration is set for more than one PT, the
one for which the registration was made last will have priority.
By word monitoring with C200HX/HG/HE, the unit number of the PT for which
priority registration has been set can be confirmed. For details on the monitoring
operation at the PC side, refer to the manual for the PC used.
