I tried all the common IP range that we use but witouth success. Is it possible to connect the PLC directly with the MAC adress? best regards Laetitia

I looked a little bit around, and it looks like more a problem with the Ethernet connexion and tia portal than with the cpu itself.

The 2nd launch of TIA portal cannot connect to a PLC no matter how hard you try (in case that is the problem).
