ASCII Entry Controls
ASCII entry controls allow you to send an alphanumeric string (up to
128 characters) to a controller. Like numeric entry controls, the ASCII
entry control can appear on a screen as a keypad enable button or a
cursor point. When either object is activated, the ASCII scratchpad
opens. The look of the scratchpad depends on the terminal.
ASCII Scratchpad - Keypad or Keypad/Touch Screen Terminals
Select characters from the Character Keyboard by moving the cursor
(with the keypad arrows) over a character and pressing the Sel-F1
function key. The character appears in the Display Area. This area
scrolls so you can enter a string that is longer than the Display Area.
All characters are sent to the controller even if not visible.
After entering characters, press
↵ to send the string to the controller.
The leftmost character is placed in the high byte of the first word (of
the write tag), the next character in the low byte, and so on.
Note: DeviceNet ASCII entry allows for byte swapping.

Terminal Keypad Moves the cursor up, down, left, or right in the Character Keyboard.
←
Terminal Keypad Deletes the character to the left of the cursor in the Display Area. If the cursor is at the leftmost
position when you press ←, the scratchpad closes.
↵
Terminal Keypad Sends the character string to the assigned write tag address in the controller.
When opening the ASCII scratchpad, the string is highlighted. If you select a character immediately,
the terminal clears the Display Area and displays the selected character. If you press a control key, the
terminal continues to display the existing string, allowing you to edit it.
SEL F1 Function Keys Selects the highlighted character and places it at the cursor position in the Display Area.
INS F2 Function Keys Toggles between Insert and Overstrike mode. Overstrike mode appears in reverse video. In Insert
mode, the selected character is inserted before the cursor in the Display Area. If the maximum number
of characters is entered in the Display Area, new characters are ignored. In Overstrike mode, the
selected character replaces the character at the cursor in the Display Area.
<< F3 Function Keys Moves the cursor one character to the left in the Display Area.
>> F4 Function Keys Moves the cursor one character to the right in the Display Area.
ESC 5 Function Keys Closes the scratchpad without making any changes.
CTRL F6 Function Keys Clears the string in the Display Area.
