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).
