Returning access on a system whose support has ended
When manufacturer support has ended, a password has been forgotten, or a PLC or HMI program is locked, access is returned to the factory that owns the system. The purpose is technical continuity of the line.
This is not a service for copying a system or entering someone else’s machine. The request comes from the end user who can document ownership. It is closed to automation companies, software developers and requests aimed at copying.
After access is restored, a backup is taken, the existing function is checked, and authority is left with the factory.
