Hi, I've created a popup screen to show an alert to the user.
Now I want to show this popup every time that a tag changes from 0 to 1, independently on which screen is activated.
I know this is possible because I've seen it on an application.
My question is how to make this?

Add an event handler to the tag and use scripting in the event handler to show the pop-up screen:

IScreen screen = getScreen("requiredPageName");
if(screen != null)
{
screen.Show();
}


public static IScreen getScreen(string pageName)
{
try
{
Type type = System.Type.GetType("Neo.ApplicationFramework.Generated." + pageName);
if (type != null)
{
return Globals.GetObject<IScreen>(type, pageName);
}
}
catch { }

return null;
}

I think this should work.
