WinCC: function Execution on a signal state change

Dear Members,

I need to execute a function(user programmed action) on digital input signal state change. It does not have any graphical object.

How can we refresh a graphic screen using WinCC function? Do we have to use a Win32API?

Once you have programmed the script, you can select the "event" property in the tag properties dialog and asign the script to the "change" sub-property.

Thanks for the reply.

Is there any way a can refresh a screen from other screen using any of Wincc Fucntion or Win32 API.

All objects in the refreshed will also be refreshed?
