Dear experts,

I am working on a WinCC V7.5 application translated by Siemens from Factory Link.

Some screen are loading fast when I change page from bottom menu but some take about 3 secondes to do so.

So I inspected code and find this VB code for page that are loading fast:

Do Until pobj Is Nothing

For page loading slowly a value 1 is assigned to a variable like "Button F6" that is used in a VB script that have only the line "HMIRuntime.Tags("APPLICATION_DRW").Write   "GLOBALE" ".

Do you know what the "Do Until" loop is doing?

Is there a reference for this in a manual?

Best Regards

Hello!

I would recommend you to check the following FAQ as a 1st step: How do you shorten any delays in the display of screens/faceplates in the PCS 7 OS?
