Socket error during Receive operation

What does ERR_SOCKET_RECEIVE mean?

An error occurred during the socket receive operation. This indicates a failure to receive data over an established Modbus TCP connection, often due to a broken connection or the remote peer not sending data.

• Physical network connection broken after establishment.
• Remote peer not sending data or sending malformed data.
• Internal network stack buffer issues or corruption on the receiving end.

Click steps to track your progress.

1. 1

   Verify the physical network connection (cables, switches) between the controller and the remote device.

2. 2

   Check the status of the remote Modbus TCP device to ensure it is actively sending data.

3. 3

   Monitor network traffic to identify packet loss, retransmissions, or disconnections.

4. 4

   Restart the controller to clear temporary network stack issues.
