PySide6.QtOpcUa¶

Detailed Description¶

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 v1.1, MPLv2

Unified Automation C++ SDK (UACpp), Commercial

Using the Module¶

To include the definitions of modules classes, use the following directive:
