Hi,

In Wincc Advance V15.1, I am facing an issue of HMI tags updation. HMI tags are not getting updated in screen even after values are changed in PLC DB. The HMI Tag values are updating in runtime screen only after screen change/refresh. I tried with different setting in tags like, Acquisition mode: 'Cyclic Continuous', 'Cyclic in Operation' and 'on demand'. Also tried with Tag Acquisition cycle setting: 1s & 100ms. But the problem is still the same.

So need help.

Hello,

What panel did you use ? If you use basic try to do new screen with one bit witch changing in PLC DB and see what happen. Basic panel have not much memory to keep elemens in one screen and maybe this not show like you whant.

I have same problem, it looks runtime is overloaded. 

Or anyone some suggestion?
