WinCC/WebUX v7.5 sp2 - slow and unresponsive during live deployment

Hello guys,

So we are implementing the WebUX functionality of WinCC 7.5 SP2 on our end. During the development phase of the project we do not encounter any problem, this includes the graphics development,navigation route as well as the tagging. We also tried some internal tag scripting to make sure everything works well. However, upon deployment of the project on-site. We encounter a slowdown until it become unresponsive. We noticed that when we connect the profinet and when the PLC on tag management started to have an established connection the webux started to slowdown until it become unresposive.

We are using around 900 tags per facility (such as boolean, real, int, double int and more).

Upon researching on the web, we found no solution yet but the webUX thing was developed almost a decade? and still no solid support or solution to this problem? why is that? I hope I can find solution in this forum. Thank you

I think you should open a support request here.

• Can you reproduce the behaviour in your tests with a PLC? - you wrote you only tested with internal tags
  
• Is it on every screen?
• Do you have cyclic scripts / tags running?
• can you check script diagnosis, logfiles, WinCC System messages for errors
• enough free ressources on the WebUX device?
