Hello, I have encountered a challenging situation regarding a machine with a password-protected PLC program in TIA V14. The supplier has gone out of business, and we are unable to locate a copy of the program. I have attempted various methods to access the PLC, including using WireShark to capture the password in plain text, but to no avail. I am looking for solutions to create a backup of the program to prevent downtime in case of a machine failure. If you have any insights or suggestions, please share them. Thank you.
Hello, I am facing a challenging situation and seeking advice from this knowledgeable community. Our machine's supplier has gone out of business, and we are unable to locate a copy of the PLC program anywhere. The PLC is password protected in TIA V14 (or possibly V15) and all attempts to access it have been unsuccessful. Is there a solution to this issue? I simply need a backup plan to avoid production downtime in case of a machine failure. Unfortunately, I am not aware of any way to bypass the PLC access protection. However, you could remove the memory card from the PLC and extract the project from it using a Siemens Field PG or a USB prommer. Another option is to perform an "online backup," but this method may require establishing an online connection with the PLC first, which may not be feasible in your situation.
I am wondering if this is effective - I have the necessary tools, including a programmer and MMC reader. I had anticipated that there would be password protection on this.
The user bmw_apprentice mentioned that they assumed there would be password protection on this feature. While they haven't personally attempted to access it with a password, it might be worth a try.
The Online Backup feature in Portal enables users to store a secure image of their compiled program, rather than an editable version. I have yet to attempt backing up a program with a 300 processor in Portal, especially one that is password protected.
Hello! I stumbled upon your query while browsing, and it seems like you may be looking for an app to crack a password. I successfully did so myself seven years ago using Step7, and I believe the same method may still work on TIA as the password is stored on MMC. Just a word of caution - be wary of scams and never pay for any hacking services.
Hi there, that's indeed a tricky situation. One possible solution could be to try contacting Siemens support. They sometimes offer help in these scenarios and might be able to provide a solution to unlock the PLC. You might also want to consider reaching out to employees of the now-defunct supplier, if they're accessible, as they might still hold the required knowledge or documentation. Finally, for future safety, reinforce the importance of keeping a backup of your automation programs. Investing in such measures can prevent such incidents in the future.
I can certainly empathize with your situation. There is a way you could try, but, tread carefully as it involves the use of a third-party software, and the risk involved is sort of high. The software is called 'S7BruteForce'. It attempts to find PLC passwords by trying every possible combination. However, be aware that it could take a considerable amount of time depending on the complexity of the password. Lastly, moving forward, I’d recommend considering migrating to a system where you have full control and access over such PLC programs - if that’s feasible for your case. It’s important for business continuity. Best of luck!
Hey there, that indeed sounds like a tough situation. One possible solution could be to use a PLC-cracking software, although it comes with its own risks and ethical considerations. Alternatively, you could consider hiring a specialist to reverse engineer the program. However, the best long-term solution might be to develop a new program with features you need. It might be costly and time-consuming initially, but would save you a lot of trouble in the future. Do review your legal obligations before trying to crack the program, though. Good luck!
It sounds like a tough spot to be in! Have you considered reaching out to any third-party automation experts or PLC specialists? Sometimes they have techniques or tools for dealing with locked programs, especially if they are familiar with the specific hardware you're using. Additionally, checking online forums or communities dedicated to industrial automation could yield some helpful contacts or solutions that others have tried successfully. Given the situation with the supplier, it might also be worth looking into reverse engineering options, but just be mindful of the legal implications! Good luck, and I hope you find a way to safeguard your program soon.
