Mitsubishi Electric · MELSEC System Q/L Series
The connection to the target device was disconnected prematurely, either before sending a response using the MC protocol or during ongoing communication. This error can sometimes be a symptom of other underlying communication issues, such as a buffer overflow (4184H).
Click steps to track your progress.
For MC protocol, ensure the connection is maintained until a response to the request has been successfully sent.
Maintain the connection until a complete sequence of communication transactions is finished.
If any other error has occurred, take corrective action for that error first.
