QModBus: Open-Source Modbus Protocol Implementation
A Qt-based implementation of the Modbus protocol for industrial control systems, providing APIs and components for building Modbus masters and slaves.
What is QModBus?
QModBus is an open-source library that implements the Modbus protocol for communication with industrial devices such as PLCs, sensors, drives, and more. It is implemented in C++ using the Qt framework and released under the LGPL license.
Some key features of QModBus include:
- Implementation of a Modbus master for reading and writing data from Modbus slave devices
- Implementation of a Modbus slave for sharing data and integrations with other systems
- Support for serial and TCP connectivity to interact with Modbus devices
- Qt-style C++ classes and APIs for building Modbus master and slave functionality into applications
- Platform abstraction allowing use on Windows, Linux, Mac OSX, and more
QModBus can be useful for developers looking to add industrial connectivity using the Modbus protocol to their Qt-based desktop, mobile, or embedded applications. Its open-source nature makes it easy to customize or extend as well.
