Hi guys,

I use WinCC Unified V16 upd1 to create a unified pc project. When I try to download project, 'extended download to device' window pops up. If I click 'connect' button, I'll get the error message 'Failed to establish a connection to ...' as the attached chart.

Sometimes I restart Virtual Box pc, the download turns ok. But most time it doesn't work.

Have you ever seen this? Could you help me give some hints?

Thank you.

Hi,

did you tested if in the fault state you can ping the device by IP / name?

Hi,

did you tested if in the fault state you can ping the device by IP / name?

 IP address 192.168.56.134 ping works well. In fact, ES and RT is in the same pc.

I suspected that the wincc unified installation maybe bad, so I resetup windows and wincc unified in virtual box pc. But it doesn't help. 

Hi,

can you ping your pc by name?

Hi Denilson Pegaia,

After installing upd2, the usability of my WinCC Unifed becomes better than before. I tried to open and download several projects, everything was fine.

Thanks for your help.
