Touch Switches
Screen Switching Function
Note:
S Inverse display on input
S Lighting and flashing
S Presence/absence of a guide display
The NT20S has a function that allows screens to be switched by pressing touch
switches on its screen, rather than by designation from the PC/Host. This function
is called the “standalone function”.
The screen number of the screen that will be displayed when a touch switch is
pressed is set for that touch switch when the screen data is created using the sup-
port tool.
If the touch switch is pressed during operation, the screen whose number was
designated will be displayed. Simultaneously, the PC/Host will be notified of the
screen number of the screen selected for display.
To set a screen number for a touch switch, use “Touch SW”, “Bit specification” and
“Screen switch” of the support tool.
Only one screen number can be set for one touch switch within one screen (or
within one overlapping screen).
If “none” is selected, only the touch switch’s guide display message (or nothing, if
there is none) are displayed until a “light” or “flash” designation is sent from the
PC/Host or the touch switch is pressed.
It is possible to set a touch switch so that its display will be inverted when it is
pressed.
It is possible to specify whether the touch switch will be lit continuously or flash
when the bit allocated to it is turned ON by the PC/Host.
A guide display message can be displayed at a touch switch location.
