Connection Failed- The selected online target could not be reached

Hello,

please can you answer the questions?
How the PLC is wiring to you Engineering PC?

Is it direct connected or some Switch /Router/Gateway between?

You see that the Engineering only find the device with the Adress 192.168.0.1, not with 192.168.0.7!

You can try the "Extended Download to device" and enter the IP direct in the adress field so that TIA use this IP for the Download and the Connection.

Regards

Christoph

I had the same problem.

Install PRONETA and restart your PC.

In PRONETA Settings, select your Network adapter, after that go to the "Network Analysis", serch for you PLC and Set the new/old IP, set a Subnet Mask and a Gateway.
In your TIA project, set the same Network config that you set in the PRONETA

Also check that your network adapter has the same Gateway and also the same SubnetMask.

Obviously all the previous comments regarding the adjustment of IP's in the same subnet are fundamental, but there is a detail (simple but fundamental) that I did not find in forums and that TIA Portal does not inform. At least in this message it is difficult (I would say impossible) to discover: "Connection Failed- The selected online target could not be reached".

It also needs to be on this screen for the first transfer. 

note: target device box is without information
