When you have scanned for "accessible devices" you go to "online and diagnostics" -> functions. Here you can assign a new IP address Best regards, Wizard

I understand that occur disabling the capacitor remanence of the CPU. Now I can update and communicate with the PG. Caution: do not think it advisable to do this when you have the backup of the PLC program. Sorry for my English, I'm using google translator Greetings.
