I cannot find PLC connected to Ethernet from tia portal
Is there anyone who can help me with this

This probably has nothing to do with VirtualBox. If you are using bridged mode, the networking is just the same as if you were using the host. Bridged mode simply lets the guest share the host's connection. It gets its own IP and is just another machine on the Internet. If you have an Internet connection on the guest, everything is working properly.

I suspect you have simply not configured the app correctly. We can't help you with that.
