Touch Switches
Section 4-7
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.
S Inverse display on input
It is possible to set a touch switch so that its display will be inverted when it is
pressed.
S Lighting and flashing
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.
S Presence/absence of a guide display
A guide display message can be displayed at a touch switch location.
4-7-2 Screen Switching Function
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.
Note: Only one screen number can be set for one touch switch within one screen (or
within one overlapping screen).
