Hello SIr,

I am currently experiencing the same problem.

I use scripring to change my screens. It is working flawless in the simulation, but screens are skipped or not shown correctly when using the HMI in realtime....

Pressing longer on the button sometimes helps. It is as if two command cannot be handled at the same time when pressing a button....

In my case, when pressing the "OK" button, the footer should change and the screenwindow_body also.... This sometimes works fine, sometimes NOT....

Maybe it is better to only change the Screenwindow Body, and then perform an 'Onloaded' action and change the footer when the Screenwindow Body is loaded...

I suspect a poor scanning of both commands when pressing a button or incorrect event handling...

Hi EL_T_M,

When you switch screens, you need to consider your screen layout. You will run into trouble if you change the screen on which a script is running. In this case, the script is aborted, causing timing problems when you switch screens.

On a PC, where you are sure to have better performance, you may find that all screens have already been switched before the script is aborted, which is not the case on a panel device. You should check your screen layout if this is causing your problems.

Kind regards
Stefan

 Hello Stefan,

What is then a better option to change screens? I have nothing running on the current or the next screens. They are only screens with a graphic and some buttons to select a product or enter an amount of products  to be produced. Is the 'Non-script' definition of changing screens then a better option?

Or should I change 1 screen in scripting and e.g. change the footer when the next screen is loaded with an 'OnLoaded' command?

Thanks,

Best regards,

El_T
