Driven by topics such as Industry 4.0 and IoT, OPC UA has established itself as the de facto standard for the communication of industrial devices and applications. Qt 5.11 ships with Qt OPC UA, a new module which has been developed by basysKom, together with The Qt Company. Qt OPC UA enables out of the box integration of OPC UA enabled devices with Qt applications. Go to www.qt.io for more information.
