Hello, If you can connect to PLC but con't access application due to un-known password, you can use master password "CLEARPLC". But be careful, because it will erase the application on the CPU and you will need to program it once again from scratch. Another way, if you cannot connect to the CPU due to un-known address / baud rate, then you can use WIPEOUT tool: Resetting the S7-200 to the factory default settings (WIPEOUT) Hope this helps. |
