Hello, 
I am trying to make my pop up window disappear after defined time (after window screen loading). I am new to java script. This is my function I thought could work, but does not. HMIRuntime.Timers.SetTimeout(HMIRuntime.UI.SysFct.ClosePopup("/Main_Menu"), 5000);
Could you advise me? Thank you in advance :) 

 setTimeout() method

Siemens has their own SetTimeout function implemented since the wincc unified object model doesn't have the Window object, but both work the same way.

setTimeout method accepts function reference as it's first parameter. In short, you need to either pass a function name or a function expression.

This will work.

HMIRuntime.Timers.SetTimeout(()=>{
HMIRuntime.UI.SysFct.ClosePopup("/Main_Menu");
}, 5000);

This should also work but I'm not 100% sure since it's siemens' implementation.

HMIRuntime.Timers.SetTimeout(HMIRuntime.UI.SysFct.ClosePopup, 5000,"/Main_Menu");

Edit: mdn documentation is an excellent source for learning javascript. I suggest that you take your time to take a look here: JavaScript Guide
