Connection Failed- The selected online target could not be reached

I had such problem also.

Solution of it was in my case:

- go to settings > profinet > "place mark" to Enable Profinet IO.

Profinet was disabled and it caused this problem.

I also had such problem.

Solution in my case: go to hardware config -> plc properties-> find there profinet settings

Need to find there such setting: "define profinet name automatically".

Problem was that in the program it was not setted up and original device name of plc was not assigned (because of factory reset). After this everything worked perfect.

I'm not able to connect to the CLP, does anyone know how to solve it?
