Functions
| Function | Purpose |
|---|---|
| Read and write | Read a confirmed point and write only to an approved test point. |
| Messages | View sent and received frames, protocol fields, and error details. |
Device debug
Enter "Development Configuration → Collection Configuration", select the current device and click "More Functions", then open "Debug".
Read and write
Perform read or write verification according to the current plugin address rules; confirm on-site security and permissions before writing.
Messages
Check the device's message sending and receiving and protocol logs to locate message format, connection and parsing problems.
Verify the configuration
Use a confirmed on-site address to perform reading. The return value, data type and byte order should be consistent with the point list; after the writable point is written, it should be read back according to on-site requirements.
Troubleshooting
- Address reading failed: Check the station number, register or node ID one by one according to the address rules on this page, and confirm that the data type is consistent with the device point list.
