QModMaster is a free, Qt-based Modbus master application. A graphical user interface provides easy communication with Modbus RTU and TCP slaves, and a built-in bus monitor lets you examine all traffic on the bus.
QModMaster is based on libmodbus for protocol communication and QsLog for logging. It supports both Windows and Linux. For Windows, a pre-compiled binary is available — no installation required, just unzip and run.
The repository has moved to GitHub https://github.com/elbarbas/QModMaster>. SourceForge will continue to host updated binary releases, but the latest source code is maintained on GitHub.

Thank you for creating a useful tool. I wish I could copy the text in the Bus Monitor and ADU windows. It is my hope that you can freely copy and paste this content into a text editor.
