The results of communication with each station are stored here. The status codes are shown below.
Errors other than the above are stored as shown below.
Solution
1) Check if the communication settings of the V9 series and the connected device are matched.
2) Check the cable connection.
3) Data may be disrupted because of noise. Fix noise.
If you still cannot solve the error even after following the solutions above, contact your local distributor.

Error Details Solution
Time-out
Although a request to send is given, no answer is
returned within the specified time.
Implement solutions 1, 2, and 3.
Check code The check code of the response is incorrect. Implement solutions 1 and 3.
Data error The code of the received data is invalid. Implement solutions 1, 2, and 3.
Error code received An error occurred on the connected device. Refer to the instruction manual for the PLC.
Buffer full The V9 buffer is full. Contact your local distributor.
Parity An error occurred in parity check. Implement solutions 2 and 3.
Overrun
After receiving one character, the next character was
received before internal processing was completed.
Implement solutions 1 and 3.
Framing
Although the stop bit must be “1”, it was detected as
“0”.
Implement solutions 1, 2, and 3.
Break detection
The connected device’s SD is remaining at the low
level.
Examine the connection with the connected device’s
SD and RD.
