ScaleStreamMaster
ScaleStreamMaster receives continuous output from an electronic scale through a serial port or reverse TCP and maps the fields to variables.
Open the plugin
Enter "Development Configuration → Collection Configuration", create a device and select "ScaleStreamMaster" in "Collection Plugin".
Supported channels and data types
| Channel type | Pre-configuration check |
|---|---|
| Serial Port | Confirm that the serial port is not occupied by other programs and maintains the same baud rate, data bits, stop bits and parity bits as the device. |
| TCP server | Confirm that the local listening address and port are available, and allow on-site devices to actively connect to the gateway. |
Optional data types: Boolean, Int32, Double, String

Use reception monitoring to check the latest scale frame and the mapped variables.
Functions
| Function | Purpose |
|---|---|
| Reception monitoring | Confirm that a complete scale frame is received. |
| Variable table | Check weight, tare, unit, stability, validity, and collection time. |
| Message statistics | Review received, dropped, and malformed frame counts. |
| Message log | Inspect recent scale frames for delimiter or mapping problems. |
Verify the configuration
- Send one stable test weight from the scale.
- Confirm that reception monitoring shows a new frame.
- Check that the weight, unit, stability, validity, and collection time update together.
- Change the test weight and confirm that the new value replaces the old value without frame fragments.
Troubleshooting
- No new frame appears: Confirm that the scale is sending continuously and check the channel, source IP, frame format, and field mapping.
- Values are shifted or empty: Check the scale output format, delimiter, check byte setting, and address field names.
- The serial port scale does not respond: Confirm port ownership and match baud rate, data bits, stop bits, and parity.
