QModMaster is a free Qt-based implementation of a ModBus master application. A graphical user interface allows easy communication with ModBus RTU and TCP slaves. QModMaster also includes a bus monitor for examining all traffic on the bus.
QModMaster is based on libmodbus <http://www.libmodbus.org/> for modbus communication and on QsLog <https://bitbucket.org/codeimproved/qslog> for logging. Supports both Windows and Linux.
For Windows a pre-compiled binary is availiable. It does not require instalation, just unzip and run.
You can download the latest stable version from here <https://sourceforge.net/projects/qmodmaster/files/qModMaster-Win32-exe-0.5.2-3.zip/download>.
Source code is availiable for Windows and Linux for compilation using Qt <http://www.qt.io/download>.

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.
