text: <s>[INST] FT Optix Open popup on a value change. Currently I'm working on a project in FT Optix. I've been working in it for a while now but I can't figure out how to open a popup in the runtime when a value changes. In the PLC there is some code running and when this is done, a value changes, when this value changes the popup needs to open. This popup should be able to open on every screen on the foreground. [/INST] If you go to the variables in your project you should see the Events section of the properties tab. You can add an event by clicking the plus sign in the top right corner of the properties tab and select Changed Event. Then you can use that event to open a popup by linking it to the UI commands for opening a dialog window (OpenDialog).\n </s>
