Hi man! As always i say, you are incridible man ^^, i made the tests here and everything was OK. Thanks man and congratulations to give your Know-How to us.
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?
If you have to use 24MB card, order 6ES7954-8LF03-0AA0, the xx02 is phase out part number. Typically a 4MB size card is good enough unless you are going to do huge project. You method will not work, your PLC will still be password protected because the HW configuration located in the card, it will work for your CPU once you use it and power up your CPU. You can upload your PLC to TIA Portal (HW & program), remove the password from the HW configuration, then download the CPU. Then you are free to use this CPU.
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.
Using the card shown in the video can reset and wipe out your PLC. The program and Password in the PLC will be gone. Then it will be a fresh device for you
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?
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 🙏.
Hello Greetings I have a 1200 blocked. Always ask me for password. I done this procedure with 2 mb Simatic memory card with a empty program, without password and full access using Tia Portal V17. But I cant get access, the PLC still have protection. Any help?
@@electricalautomation HI, Sorry for this late response Thank you for your time to respond, it really took me a while to try this again. You were right that the 2mb card was not listed on the cards for the procedure. so I bought a 4mb model 6ES7-954-8LC03-0AA0 But I still can't erase the CPU I follow the same procedure that you do in the video. After configuring the card as transfer, a S7_JOB.SYS file and a SIMATIC.SYS folder appear, is that normal? Any ideas, what am I doing wrong? I am with a CPU 1212C Firmware V4.6 with TIA Portal V17

Hi My friend! I remember you are my subscriber since my channel was setup three years ago. Thanks again! I am super glad the videos could be helpful!
Thank you for the info, very valuable and easy to follow
Glad it was helpful! Welcome!
Saved my bacon with this video. Many thanks man.
Thanks Buddy, Glad it was helpful.

What happen if i format the memory card before insert it ?

I Will to try this way, thanks for your information, i hope this can work
Please try, and it should work.
Great job 👍
Thank you! Cheers!
This was helpful, thanks.
Glad it was helpful! Welcome!
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?
Sorry, it doesn't work. Once you use a empty card to reset the CPU, the program is gone.
Very useful, Thank You!
Welcome!
Thank you, very helpful!

Windows biçimlendirme yapılmış bir siemens sd kartın geri dönüşü varmı? Şuan tia portal programı sd kartı görmüyor seri numarası yok oldu
No, DO NOT USE WINDOWS TO FORMAT SIEMENS CARD. If you do, it can not be used for PLC anymore.
If I don’t have original backup after that will it work ?
No, sorry. The card is used to 'RESET' the PLC, it will wipe out the PLC. You will lost the program. Therefore, you need original TIA Portal program.
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 🙏.
No you can not run because the SMC card was set as "transfer" rather than "program"
@@electricalautomation But couldn't you plug the SMC back into your computer and set it back to program in TIA?
Hello Greetings
I have a 1200 blocked.
Always ask me for password.
I done this procedure with 2 mb Simatic memory card with a empty program, without password and full access using Tia Portal V17.
But I cant get access, the PLC still have protection.
Any help?
I think you missed some operations. Also I don't think the video shown the 2mb is available for the reset operation.
@@electricalautomation HI, Sorry for this late response
Thank you for your time to respond, it really took me a while to try this again.
You were right that the 2mb card was not listed on the cards for the procedure.
so I bought a 4mb model 6ES7-954-8LC03-0AA0
But I still can't erase the CPU
I follow the same procedure that you do in the video.
After configuring the card as transfer, a S7_JOB.SYS file and a SIMATIC.SYS folder appear, is that normal?
Any ideas, what am I doing wrong?
I am with a CPU 1212C Firmware V4.6
with TIA Portal V17
nice video man
Glad you like, Thanks, Hope it could be helpful.
also works with TIA V12?
This is the hardware related operation, you could try, V12 should be the same operation.
This works for Fail Safe CPU S7 1500 also?
S7-1500 has memory card and it also come with reset switch. It operators difference with S7-1200
@@electricalautomation so do you have solution for S7 1500?
Hi there, Can this be done on a 4 MB card?
Yes, as long as the size of the program in the CPU load memory is less than the card.
Hi, will this work with plc 1500?
Yes
Well done thanks
Thanks, Hope it could be helpful.
Can it unlock Password S7-1500?
Not really, this is for reset CPU, not for crupt a sealed program.
Any idea to open locked FB?
Sorry I have no idea on unlock FB.
hi, thanks for the video…. can it work with mc 512 kb? mod. 6ES7953-8LJ11-0AA0? thank you
Hi, unfortunately, 6ES7953-8LJ11-0AA0 is the S7-300 card, and it does not fit for S7-1200/S7-1500
