(*) Numeric key number 227 (formerly “buzzer stop” + [
↓
] + [
↑
]) is the system
menu display key.
To create a touch switch for a user-defined numeric key, select “Numeric key” from
the “Touch SW - Bit setting” menu of the support tool, then designate a touch
switch number at “Numeric key #”.
When a touch switch allocated as a numeric key is pressed, the touch switch sta-
tus is not notified to the PC. Consequently, touch switches 227 to 255 cannot be
used as ordinary touch switches.
Continuous screens and overlapping screens
Numeral setting screens cannot be registered as child screens of continuous
screens. If a numeral setting screen is displayed part way through a continuous
screen, the system keys created as touch switches - [

] and [
↓
] - function as
keys for numeral setting, making it impossible to switch screens.
In the case of overlapping screens, only one of the screens can be set as a nu-
meral setting screen.
