Qt OPC UA
The Qt OPC UA module implements a Qt API to interact with OPC UA on top of a 3rd party OPC UA stack.
The stacks are integrated as plugins and can be selected at runtime. Currently, the following implementations are supported:
- Open62541 v0.3, MPLv2
- Unified Automation C++ SDK (UACpp), Commercial
The QML API as well as the security related C++ API are still in development but are available as a technology preview. This means those parts are unstable, likely to change, and provided as a convenience only. All functions and classes of the C++ API, which are related to security, state in their documentation if they are technology preview.
To include the definitions of the module's classes, use the following directive:
