3:13 · Published Jan 2026

Platform: Siemens

Recover passwords for Siemens S7 PLCs (S7-200, S7-300, S7-400), including FB, POU, and project protection. If you'd rather have it handled, I provide manual Siemens recovery support — done personally, with nothing sold or downloaded from this site.

Supported software & hardware

  • Siemens S7-200 (Classic & SMART), S7-300, S7-400 CPUs
  • STEP 7-Micro/WIN, STEP 7-Micro/WIN SMART, SIMATIC Manager / STEP 7 Classic
  • FB (Function Block), POU, and project protection passwords

Who this is for

  • You forgot or lost the FB / POU / project password on your own S7 project
  • A previous engineer left and no password record was kept
  • You've inherited a legacy S7-200 / S7-300 / S7-400 project you legally own

Locked out of a Siemens project you own?

Send the software and version, and a short description of what you're locked out of. The work is manual and done personally — no tools sold, no downloads.

Questions

Which products and versions does this cover?

It applies to Siemens S7-200 (Classic & SMART), S7-300, S7-400 CPUs, STEP 7-Micro/WIN, STEP 7-Micro/WIN SMART, SIMATIC Manager / STEP 7 Classic, FB (Function Block), POU, and project protection passwords.

Who does the recovery?

I do, personally. Every job is manual — it isn't automated with a tool and it isn't resold to anyone else.

Do I have to own the equipment?

Yes. I only help owners and authorized maintainers regain access to their own projects — in line with the authorized-use-only policy on the channel.

Do you sell a tool or a download for this?

No. There are no tools for sale and no downloads on this site. Recovery is a manual service I perform or guide you through.
