Hello, If you are the programmer, Then you should have a backup of PLC program. If not, I am sorry to tell that you won't be able to modify anything in the CPU! The only possibility is to reset the CPU to factory setting and reprogram it. S7-200 has 4 protection levels as per the attached picture. For Level 4, you can not upload the program even if you know the password. To reset the CPU to factory setting, Please use WIPEOUT tool and please note that if you used WIPEOUT tool, you will lose user program, data blocks and all confugration settings. Resetting the S7-200 to the factory default settings (WIPEOUT) |
