Touch Switches
Section 7-7
Reference
- Input into character string input fields is also possible using the “control key”
touch switches (0 to 9, A to F), and from a bar code reader connected to the
NT31/NT31C.
- A “control key” touch switch (ENT or [ ]) is also necessary to confirm input
character strings when “character string setting” is used.
S Control code input function
Control keys are used as numeric keys (0 to 9, A to F) for the numeral input func-
tion, and as special keys with fixed functions. By assigning an control key to a
touch switch, it can be used to execute a specific function.
The attributes for control keys are as follows.

Reference
- When the “window opening” bit of the PT status control area is set to “1” (dis-
abled), it is not possible to open windows by operations at the NT31/NT31C
such as touch switch operations.
- By associating windows with the “cursor moving key” touch switches with the
Support Tool, windows can be opened by pressing the cursor moving keys.
