Abstract: A system for restricting physical access to at least one component process control system component has a locking device that is integrated with process control system security administration data. The locking device accesses the process control system security data when authenticating a user. Upon authentication of a user for physical access to the particular process control component, the user may directly access the component for which the user is authorized. The system provides tracking of all authenticated users and attempts to access the various control system components.
