<p>The drives i.e. control and monitoring devices (1, 2), have display units (5, 6) for representing information (14, 15) in different zoom levels. Sensors (11, 12) detect a distance of a user (13) from the display units. The devices adjust the zoom levels based on the distance. The devices associate the zoom levels to the distance in menu-driven manner. The devices filteredly display the information based on relevance levels associated to the information. The zoom levels are selected so that the user read and/or detect the information despite of the distance.</p> |
