Our customer has a KRC4 robot KSS 8.5.6 with the option Safe Operation3.4.5.
The machine builder that commissioned the robot does not exist anymore. The customer has no passwords, no received source code of the robot and of the plc that is Profinet controller of the Kuka.
We now should want to change some settings in the safety zones. We don't know the 'safety maintenance' password, it is not the default.
The administrator password is the default.
We succeeded in uploading the project from the controller, so we have now the Workvisual project of the controller.
After implementing the changing we will do a complete safety acceptance as necessary, and take full responsibility of the installation.
Is it possible to make changes in safety in Workvisual and then deploy to controller, although we don't know the actual 'safety maintenance' passwoord? Or should more things be done on the controller to overcome the fact that the 'safety maintenance' password is not known?
