Ethernet I/F Error - Connection Disconnected

What does 4185H mean?

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).

• Connection to the target device disconnected before sending a response using the MC protocol.
• Connection to the target device disconnected during communication.
• Other errors, such as 4184H, may be contributing to the disconnection.

Click steps to track your progress.

1. 1

   For MC protocol, ensure the connection is maintained until a response to the request has been successfully sent.

2. 2

   Maintain the connection until a complete sequence of communication transactions is finished.

3. 3

   If any other error has occurred, take corrective action for that error first.
