Touch Switches
The NT620S/620C has a function whereby input operations can be performed by
using touch panels displayed on the screen. NT620S/620C screens can be
switched, or bit information sent to the PC, by pressing (lightly touching) the
“touch switches” in a panel.
The touch switches can also be made to light up (or flash) and go off like lamps.
Touch switches are set when creating the screen data with the support tool.
The following explanation covers the types of touch switch that can be displayed,
and functions other than that for notification to the PC.
For the actual method used to notify touch switch statuses to a PC, see “Lit
(Flashing) and Unlit Touch Switch Statuses (Changing the Contents of Allocated
Bits)” (page 216).
For the actual method used to ascertain touch switch statuses at the PC, see
“Notifying the PC that a Switch has been Pressed (Determining Touch Switch
Status)” (page 217).
Caution
- Do not use the PT touch switch input functions for applications where danger
to human life or serious property damage is possible, or for emergency switch
applications.
- Press touch switches with a force of no greater than 20 N. Applying higher
force may cause glass to break, cause injuries, and prevent operation.
- Do not press touch switches carelessly while the backlight is off or while noth-
ing is displayed on the screen.
Only press touch switches after confirming system safety.
