OK so I created a simple VOT screen,,compiled and downloaded it to an ET200SP with firmware 2.92. It showed up in my browser but subsequent updates did not update the web server so the intial downloaded VOT screen remained.

When I deleted the VOT from the project and recompiled and downloaded I received a 404 error in the browser. as expected.

I created a new VOT application and screen, recompiled and downloaded but the old VOT screen reappeared instead of the new one so the server :-

1. Would not update the web server after the intial VOT download

2. Did not truly delete the intial VOT from the server when instructed to

3. Did not load a subsequent VOT application but just displayed the very first one downloaded to the CPU

So to summarize VOT is not working in TIA Portal V17 with a ET200SP  (6ES7512-1SK01-0AB0) v2.92 firmware.

So what gives ?

Did you visit the controller's properties for the web server and hit the generate blocks button after making changes to the user web pages?

Thanks for your reply but 'Generate blocks ' under User-defined pages is for user defined html pages not the View of Things as far as I can tell.

Did you try it at least?  I understand the VOT is a WinCC creation that generates custom / user web pages for you in the WinCC unified environment.

Did you follow along the sample at this link: https://support.industry.siemens.com/tf//br/pt/posts/simple-sample-vot-using-wincc-unified-to-create-s7-1500-web-pages/262324/

Yes I tried it and got an error saying no directory for the web pages was found.

However it appears my problem is with the Firefox browser not clearing the previously cached webpage. I'll re-start Firefox and see if its persistant.

Edge browser seems to be ok

Problem solved. Thanks for your input

All the best

Glad you got it working, and even more happy to know it had nothing to do with my guessing the right answer (and being wrong!).
