Questions

Which products and versions does this cover?

It applies to GX Works3 projects (block password / POU protection), iQ-R / iQ-F / FX5U / FX5 controllers, Function Block (FB), Program Organization Unit (POU), and program block protection.

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.
