Hello engineers 

I have a MP277 10" KEY panel and tried to transfer program to the panel with Wincc flexible advanced. I used 140.80.0.1 for the panel and 140.80.0.13 for my PC.

when I use CMD to ping this IP  everything is ok. In the Transfer window there is a box which I should enter computer name or IP address,  I entered the IP and the device name of HMI and also my pc, but when I try to transfer the following message comes up, so cant continue this procedure. 

"Couldn't establish a connection , please check setting interface cable ..." 

So in your Idea what should I check or do?

Hello,

yes that error also point to question what cable or connection you expect for download of project. What settings you've set with this conenction option? I recommend check manual to your expected panel (family) where you can read important infos about download and other possibilities, requirements.
