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

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).
