Using the System Area
●
• When finished entering text by pressing ENT, 1 is written to the System Area 2 Character Input Setting Complete
bit (address number+3, bit 5).
• When CAN is pressed, entry mode is canceled and 1 is written to the System Area 2 Character Input Setting Cancel
bit (address number+3, bit 6). However, if the keypad is closed by pressing
bar or another Character Input is pressed and selected before finished entering the text by pressing ENT, entry
mode is canceled and 1 is not written to the System Area 2 Character Input Setting Cancel bit (address number+3,

the Character Input keypad is pressed in entry mode, select the Clear Keypad bit in System Area
automatically check box on the System tab in the Project Settings dialog box.
