“Screen number 0” is set
to the touch switch 1.
Only a touch switch can have the screen switchover return key function. If dis-
play of screen number “0” is specified from the PC, the screen will go blank.
The number of screens that can be returned using the screen switchover return
key is a maximum of 32 screens. However, it is assumed that the screen switch-
over return key has been set to all screens to be returned.
4-7-3 Input Key Function
This is a function that allows touch switches to be used for input and is mainly
used when using numeral/character string setting functions. Input keys are clas-
sified into the following three types:
Character keys: Used to input character strings when using a character-
string setting function. For details, see 4-9 “Character-
String Setting” (page 168).
Window keys: Used to open and close windows when using the pop-up
window function. Also used to switch between “key-
boards” when using character-string setting functions.
For details, see 4-9 “Character-String Setting” (page 168)
or 4-10 “Pop-Up Window Function” (page 171).
Control keys: Used for functions provided by the system, such as the
numeric key function used with numeral setting functions,
the system key functions provided with previous PT mod-
els, and special control functions. For details, see the
next section “Functions of Control Keys”.
