Functions
| Function | Purpose |
|---|---|
| Reception monitoring | Use Reception monitoring to inspect mapped values, status, counters, recent messages, or the latest result. |
| Client | Check the connection state and the latest connection result. |
| Message log | View the latest messages received by the current debug session. |
Verify the configuration
Let the field device send a test message; a new reception record should appear in “reception monitoring”, and the corresponding variable value and collection time should be updated synchronously.
Troubleshooting
- There are no new messages in receiving monitoring: Confirm that the field device is actively reporting, and check the monitoring channel, message format, and variable field mapping.
- The device is not connected: Confirm that the device has actively connected to the gateway listening address and port, and check the firewall permission rules.
