We use shared memory!
A Qt Gateway provide shared memory for process, setting ane messages.
A Qt remote PLC comunicate with gateway via UDP/TCP/RESTFull.
We developed 2 framework, the first in use in many production machines, the second in road to be implemented in new applicaitons.
In second framework we made also a QML simplified data mapping.
Data excange is made via predefined structs. A tool that extend qmake process dump xml plcopen and phyton scripts to import structs in CODESYS avoiding double works that frequently bring in mistakes.
I am trying to use QWidgets to display. Codesys runtime is version 3.5.17. Can anyone provide a minimal example of that?

In attached image you can see QML test.
