I propose adding a native iFrame component to PLCnext Engineer / HMI environment to allow embedding third-party local web interfaces directly into the application view.
Use case:
In production I use Cognex DM 370/470 camera systems with their own web interface available in the local network. When a DataMatrix code is not read successfully, I need immediate visual access to the camera image.
Currently the only option is opening the camera web interface in a new browser tab via a link or button. This breaks workflow, forces context switching, and requires unnecessary tab management.
Requested functionality:
ā¢ Add an iFrame UI component
ā¢ Allow loading local network URLs (e.g. camera web interfaces)
ā¢ Support dynamic visibility based on PLC variables or conditions
ā¢ Enable full-screen overlay mode
Expected behavior example:
If a DataMatrix read fails ā automatically display a full-screen overlay containing the camera web interface via iFrame ā operator immediately sees the image ā no tab switching ā no external browser interaction.
This would significantly improve operator workflow, reduce reaction time, and keep all diagnostics inside a single HMI interface.
The same approach would also be useful for integrating other local web-based devices (vision systems, scanners, diagnostic tools, etc.).
This feature would improve usability and system integration in industrial environments where multiple devices expose web interfaces.
