Saved my bacon with this video. Many thanks man.

This was helpful, thanks.

Thank you, very helpful!

Very useful, Thank You!

Great job 👍

I Will to try this way, thanks for your information, i hope this can work

nice video man

Can you explain me if i think good? Can I access protected program if i have two cards (one with original protected program and second empty) using this method?

Well done thanks

Hi. Thanks for sharing the knowledge. My question is, I somehow manage to get the upload from the password protected PLC. Now I have the uploaded project in my hand. But I don't have the original project. In this case, I'll use the SMC card in transfer mode and wipe it the protected PLC. After that I can download the uploaded project to that empty PLC directly right? Waiting for your reply.. Thanks in Advance.

If I don’t have original backup after that will it work ?

I really enjoyed your video, thank you for sharing such valuable content. I have a couple of questions regarding my PLC CPU. I'm looking to choose proper memory, but I'm a bit confused about which memory card to choose. Option 1: 6ES7954-8LF02-0AA0 This seems to be a spare part for SIMATIC S7, offering 24 MByte memory with 3.3V Flash, suitable for S7-1x00 CPU/SINAMICS. Option 2: 6ES7954-8LF03-0AA0 Similarly, this memory card is designed for S7-1x00 CPU/SINAMICS, providing 24 MByte memory with 3.3V Flash. For my second query, my CPU has read access but only write access is protected. If I reset the CPU from online and diagnostics, then reload the original program backup after removing the password, would it work?

Hi there, Can this be done on a 4 MB card?

Hello sir, If I did that and upload the program to SMC from protected PLC , i know the program will be lost , but can I put the SMC in PLC and run normally? Because I have a program uploaded in SMC ?? PLEASE 🙏.

Any idea to open locked FB?

also works with TIA V12?

Hi, will this work with plc 1500?

This works for Fail Safe CPU S7 1500 also?

hi, thanks for the video…. can it work with mc 512 kb? mod. 6ES7953-8LJ11-0AA0? thank you
