# PIN Settings

Using a PIN prevents unauthorized usage of the controller or accidental changes. It is possible to have one or many different PIN configurations on the controller and one of the ways of configuring is through the ToolsTalk 2 Software. Users can decide whether or not to activate one or several PIN configurations at the same time. A maximum of ten users can be added to the controller, each with their own PIN.

Each PIN configuration has a PIN code, a user name, a switch for enabling or disabling the user/PIN, and a list of available configurations that the user can access.

When PIN is enabled and the screen is locked, a locked padlock icon is shown at the upper-right corner of the GUI. The user can access and make changes only to the selected configuration(s) without entering any PIN code, and browse the unselected configurations with read-only access only. The unselected configurations are greyed out or disabled.

The screen lock goes automatically on after a certain time of inactivity, configurable by the user.
The minimum value of the inactivity time is 20 sec and the maximum value is 600 sec. The inactivity time is configurable and applies to all PIN configurations.

After a system startup, the controller is locked if the PIN is turned on, regardless of the current inactivity time.

When PIN is activated, a PIN code is required when accessing the controller via:

- The controller GUI

- The web GUI
