UserControl files
Every UserControl is represented by 2 files:
- *.usercontrol
- *.usercontrol.json
Several UserControls to use with the Graphic Control property can be requested as an example by e-mailing processindustry@beckhoff.com. They should just be added to the HMI project which uses the HMI Process Library. For example, “UserControls” folder can be added to the HMI project and then desired UserControls can be added in it as Existing Items:

Simply choose *.usercontrol files and the corresponding *.json files will be added automatically.
