Device debug
Enter “Development Configuration → Collection Configuration”, select the current device then open “Protocol Debug” at the top of the workspace.
Dedicated debugging page
The protocol debugging page is used to execute the DL-EN1 command and view the returned results.
Debugging notes
Use field-confirmed sensor commands without side effects first; any commands are processed as high-risk operations and confirmed twice.
Functions
| Function | Purpose |
|---|---|
| Plugin operation | Use the controls on this plugin page and review the returned result. |
| Execute command | Use Execute command with an approved test point and confirm site safety before execution. |
Verify the configuration
Compare the raw response with that command’s response definition and the sensor display; ordinary register variables are not provided.
Writes and control operations require an approved test point and the site safety procedure.
Troubleshooting
- Commands depend on the attached sensor. Do not substitute another sensor’s command or a Modbus address; check command terminators and error responses.
- Special method execution fails: Check method parameters and permissions; control, write or reset methods also need to confirm that the device is in a state that allows operation.
