PIN Settings
Using a PIN prevents unauthorized usage of the controller or accidental changes. A maximum of ten users can be added to the controller, each with their own PIN. Note that PINs are not linked to controller configurations and are used mainly for logging in reasons.
When changes are made to the PIN or if any modification is done on the controller GUI or WebHMI, the user that made the changes is logged. This will be displayed in the column Changed by in the External change notifications window, and added to the change history.
When PIN is activated, a PIN code is required when accessing the controller via:
The controller GUI
The web GUI
