Hello Dear Users,

I have the following issue with turning on the visualisation on specific panel ( attachment below )
Im working in TIA portal v14

The error says that the:

"The local computer name could not be found in PLC or the HMI connection to PLC could not be established!"

Despite the fact that the:
> Name of the computer where i want to turn on the HMI is correct,
> PG/PC interface is set correctly on PC as well as in "Connections" section in HMI options,
> IP adresses are set correctly, 
> even if i log in as a user, i cannot choose the hmi panel

On the screen which i've uploaded, i cannot "choose" the correct HMI panel where the name should be shown.

I tried to rebuild the whole soft, generate sivarc again and reset the PC
Is there a specific FILES responsible for connection between PLC and PANEL?

Thanks a lot for Your time reading that issue, Cheers.

Hello,

Please could you specify more details about PLC and HMI Connection to us ?

Hi,

Did you try  -> reset_wincc.vbs  

Must be sure hmi device access point is same with PG/PN settings
