Command: Reset origin
Call: The button in the device editor of the safety controller in the Tab: Safety Online Information
Function: When the Reset origin command is executed, the current application is unloaded, the boot application is deleted and the admin password is reset (or the system-specific default password is re-activated) and the release for teleaccess is reset. The logs are not deleted. Authorization with the admin password is not required in order to execute the command.
When the user is currently logged in to the application of the device instance, the command is executed only after confirmation by the user and the online connection is terminated.
The user always gets a feedback message as to whether the command has been successfully executed or not. This feedback message must be confirmed by the user. If the command could not be successfully executed, the message opens: The safety controller could not be completely reset appears. Important: Under certain circumstances, the boot application may become active again at the next start of the controller. This message must also be confirmed by the user.

Deleting the administrator password
Tip
If the administrator password is lost, the old administrator password can be deleted using the Reset origin command.
Subsequently the boot application must first be created again in order to be able to assign a new administrator password.
Notes on the decommissioning of the controller
Caution
Before a safety controller is decommissioned and removed from the plant, the boot application on the safety controller must be reset by means of "reset origin". This prevents the safety controller from unintentionally starting with the "old" boot application if it is re-used in another plant.
Caution
An incomplete execution of the Reset origin command can lead to the boot application remaining on the controller and becoming active again when the controller is next started.
