Using a Bar Code Reader
You can use the bar code reader to enter numeric bar code values
into the Numeric Enable Button object.
The Numeric Keypad Enable Button object reads only numeric
values. If your bar codes are alphanumeric values, the alphabet
values will not be read into the Numeric Entry scratchpad.
Only the PanelView 1000e and 1400e terminals support a bar code
reader. For connection details, see “Using a Keyboard or Bar Code
Reader” in Chapters 2 and 4 of the PanelView 1000e, 1200e, and
1400e Operator Terminals User Manual.
To have the bar code reader automatically read and send values to
the PLC, program the bar code reader to send Enter automatically to
the PanelView terminal.
To enter a value with a bar code reader:
1. To activate a Numeric Keypad Enable Button object, press the
Function key that corresponds to the Numeric Keypad Enable
Button object on the PanelView keypad terminal.
2. Scan the bar code.
The scanned bar code value is displayed in the Numeric Entry
scratchpad.
3. To send the data to the PLC, press the Enter key on the keypad
terminal or set up the bar code reader to send Enter automatically
to the PanelView terminal.
Configuring the Numeric Keypad Enable Button
Configure the Numeric Keypad Enable Button according to the
following table:

be retained or removed after the operator presses the Enter
key:
