You have Control Expert v16.00, which has a different protection version than older programs. Unfortunately, we can't help you.

Hello,
To access the Centritune section, we need to unlock the "Section & Program Units" password.
Thank you.

Hello. Could someone assist me? I have a Control Expert Classic v15.3 PLC project for M580 plc. The password to open the project is: Prog@123321. The issue is that the Section & Program Units password is missing from the project. Could someone please assist me in decrypting this?
The project : https://limewire.com/d/VujlB#cjjMi5kbvM

Re: [?]: Unprotect Schneider PL7-Pro DFBs
Hello,
@vlad2006gr First of all, thank you all for your help.
As you mentioned, I've been trying everything with the Hex Editor for two days and I've been unsuccessful. Can you explain this issue to us or to me step by step and help me?
And if possible, could you send me a video about it?
The PLC program I'm using is PL7 Pro V4.5. In my project, the blocks in the program section are locked, and no one knows about this lock, and the person who wrote the program is also dead.
I would be grateful if you could help me with this.
Regards,
Enes

Re: [?]: Unprotect Schneider PL7-Pro DFBs
Hello everyone,
I’m working on a Schneider Unity Pro project that is password-protected, and I’m having trouble accessing it.
To be clear: this is a project I am authorized to work on, but the original password has unfortunately been lost.
I followed Vlad’s explanation from the previous thread and was able to extract the passwords for the DFBs without any issues.
However, I still can’t locate the password for the main project or for the protected sections, and I’m stuck at that point.
Has anyone experienced this before, or does anyone know if there is a method to recover or reset the project/section passwords when you have legitimate access to the equipment?
LINK: https://www.mediafire.com/file/1bwz6prndhdj2ho/CEG-0037.zip/file
Any guidance would be greatly appreciated.
Thanks in advance!

Hello and Happy New Year to everyone. Below is a link to an old M340 with a password on the project, which has read and write access. I can't recover the password, as it's not encrypted. Do you have a procedure for removing it? Thank you all.
