If the special window screen (such as the popup keypad for data display parts) displays first, the keypad registration does not display when you touch the keypad for the RPA window screen. However, if the keypad registration for the RPA window screen displays, the special window screen can be displayed and operated.
Refer to the following for the special window screen.12.9 Displaying Multiple Windows on a Single Screen
The popup keypad closes when you change screens, turn off the RPA display window, or go to offline mode.
You cannot use the auto repeat input function (inputs while you hold the key) with the popup keypad.
The [Single Byte/Double Byte] key displays only when the [System Settings] [Display Unit] [Menu and Error Settings] [System Language] is set to Japanese.
The popup keypad display is not supported when the display unit's [Orientation] is set to [Portrait].
When [Caps Lock] is enabled on a USB keyboard, it affects inputs to the popup keypad (type as if the [Shift] key is pressed).
When [Caps Lock] is enabled on a popup keypad and you type [Ctrl]+any key, it inputs [Ctrl]+[Shift]+any key. When typing [Alt]+any key, it inputs [Alt]+[Shift]+any key.
