How do you do that exactly ?John Gaunt said:It was just a matter of
putting the MMC card in a reader attached to a laptop

Hello:
I have the same problems with a simatic CPU 315 2DP with a MC Flash. I have a program to unlock the cpu but it work by brute force method.
I have readed in a forum that it is possible to unlock the CPU password reading the MC card in external prommer.
Any bady know somthing about that?
Best regards and excuseme my poor English!
All .I have an S7-300 PLC that has had its CPU password protected.
Can anybody help me unlock it?
I don't have its Step7 project and want to download its
blocks, create a symbol table and be able to make some
necessary changes to its program. I am familiar with Siemens
Statement List (STL) programming.
Again, can you help unlock this CPU.
How do you do that exactly ?
Do you mean that you are using the Siemens MMC card reader and STEP7 software, or are you using just any MMC card reader and copy the files to just a "regular" folder on the PC ?
If I put an MMC card in a normal MMC card reader, it cannot see anything on the card. You can only format the card (which off course, I dont).
But i need the plc mmc from your existing plc cpu then i can help to unlock the plc password .
Well there are some people here who replaced password protected CPU. give your mail id so that we can help you out.
