Modbus Slave UDP Start Failed

What does 0x00090006 mean?

The MODBUS slave failed to start successfully in UDP mode. This diagnostic message is permanently stored, indicating a problem with the UDP server's initialization, potentially due to configuration errors, resource conflicts, or network interface issues. This will prevent MODBUS UDP communication.

• Incorrect MODBUS slave UDP configuration settings within the WBM client
• UDP port conflict with another UDP application or service running on the controller
• Network interface card (NIC) issues preventing UDP binding on the controller
• Insufficient system resources for MODBUS slave UDP operation

Click steps to track your progress.

1. 1

   Verify the MODBUS slave UDP configuration settings using the WBM client.

2. 2

   Check for other applications or services using the same UDP port as the MODBUS slave.

3. 3

   Ensure the controller's network interface is active and properly configured for UDP communication.

4. 4

   Review controller system logs for more detailed network or resource errors related to the failure.
