Hi!
Im trying to show popup window on internal tag change from false to true, but it doesnt work.. I write in source code this code (this code in Main [..]):

If [test_bool_tag]==true;
[
  \DisplayManager\ShowPage("test_page");
]

Maybe I'm doing something wrong or other better ways to do this?

I tend to use something like the below, the help files will show you the Edge function. I use the tags unique ID, and a timeout to avoid any pulse changes (if desired..).

I have this on a page .SRC so that the popup only occurs whe the user is on a certain page.

If Edge(TimeOut(Scope(\VTSDB, "ai98m.t!gn\05vod$kkj1", TRUE)\Value,2),1)  ;
[
        \DisplayManager\ShowPage("Reports1");
]

Make sure the called page is configured as a pop-up. Also assuming you are importing changes to the application etc.

thank you, its work!
How can I do that a window open only once? Now after close button the window popup again open.
Now my "test_bool_tag" every time is true.

The referenced tag is set to a 1 when I want to open the page, I then set it to 0 once the page is open, so the below goes onto the pop-up page .SRC: so you'll need to plan what triggers this tag etc.

If Scope(\VTSDB, "ai98m.t!gn\05vod$kkj1", TRUE)\Value <> 0;
[
        Scope(\VTSDB, "ai98m.t!gn\05vod$kkj1", TRUE).Set(0);
]
