If data is not written normally, confirm the following points.
• When data is not written to the PLC
Action 1: Confirm the version of the GOT and the screen creation software.

Screen creation software: SW
o
D5C-GOTRE-PACK: V.G or later

Action 2: Confirm the bar code reader specifications.
Make sure that the contents in "13.2.2 Communication specifications" are satisfied.
Action 3: Confirm the wiring.
Action 4: Make sure that all of the bar code input signal, the bar code input invalid signal
and the bar code input read completed signal assigned to the system information
(control devices) are OFF.
If any signal is ON, data cannot be written.
* When the bar code input read completed signal becomes ON in the PLC, the
GOT sets to OFF the bar code input signal. (Refer to Paragraph 13.2.3.)
• When data is partially written to the PLC
* After receiving the end code (CR: 0DH) from the bar code reader, the GOT writes data to
the PLC.
Accordingly, it does not usually occur that data is partially written.
Action 1: Confirm the setting of the bar code in the screen creation software.
Especially, the number of devices may be small.
Action 2: Confirm the bar code reader specifications.
Action 3: The data may be interrupted while being transferred.
Check whether there is imperfect contact.
