Hi, 

I have an issue with downloading the OPC (TIA Portal) to the PC (Industrial PC).

In the TIA, everything is ok and I tried even the same program of the last machine which worked well but the problem is that PC doesnt show in the TIA. 

When I go to the Online access, click on update accessible devices and he says that there is no device, followed by System Error (Message 140:511). 

Could someone please assist me in this issue.

Hi,

Thanks for your reply. I was on site and have no idea which IPC used. 

As we had no time, I used the Spare IPC and everything worked in few minutes while the first IPC after 4 hours of searching and trying did not work. 

However, I think that the PC had no Tunnel to communicate which is more an ICT problem.
