Project? Upload your project to a file-sharing service, and they'll try to help you.

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

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
