: Reads and writes Coils (FC1, FC5, FC15), Discrete Inputs (FC2), Holding Registers (FC3, FC6, FC16), and Input Registers (FC4).

If you prefer an app that works out of the box on macOS, these native alternatives provide similar Modbus TCP/RTU master capabilities:

: The software supports multiple data formats including Boolean , Integer , and Floating-point values, which are common in industrial sensor monitoring.

Unpack the zip file, navigate to the directory in your Terminal, and run the compilation commands using qmake and make : qmake qModMaster.pro make Use code with caution. qmodmaster mac

There is no official pre-compiled binary for macOS, unlike the convenience of a Windows executable. However, the process of building QModMaster from source on macOS is straightforward for users comfortable with development tools.

At its core, QModMaster is built upon two major open-source components: , which implements the Modbus protocol core for efficient communication across multiple platforms, and QsLog , a concise yet powerful logging library that ensures program traceability and debugging convenience.

As an open-source project, QModMaster benefits from community contributions and shared knowledge. Several GitHub forks and repositories maintain the codebase, including the main repository at SourceForge ( https://sourceforge.net/projects/qmodmaster/ ) and active forks on GitHub such as andraxsnakesecurity/qModMaster and xakod/QModMaster .

Ensure your Mac and the PLC/device are on the same subnet.
