Protocols
Protocol decoding, in the Professional edition
Six protocol plugins ship with the build, and decoding is a Professional feature: in the free, trial and standard editions the Protocol and Modbus views stay visible, but every decoded value is replaced by ****.
| Protocol | What you get | Where to look |
|---|---|---|
| Modbus RTU | Function code, register address and CRC decoded into fields | Protocol, Modbus |
| Modbus ASCII | The same fields, ASCII framing | Protocol, Modbus |
| DL/T 645 | Metering frames recognised and decoded | Protocol |
| IEC 60870-5-101 | Telecontrol frames recognised and decoded | Protocol |
| NMEA 0183 | GNSS sentences recognised and decoded | Protocol |
| AT commands | Command and response lines recognised | Protocol |
Plugins can be enabled, disabled and reordered in Settings. The mask is not a capture limit: frames, lengths, directions, timestamps and raw bytes are always there - only the decoded values are replaced by ****.
