We present a method to visualize a large mount of monitored values of Supervisory Control And Data Acquisition (SCADA) systems on small screens of cell phones using supervised equipment and its relations. The aim is to provide easy views and navigation on small screens for operators to obtaining information about plants and to ascertain plant status in cases of emergency. In this method, pieces of equipment and relations between them form an equipment graph, and closely related pieces of equipment are shown by extracting them from the graph based on a focused piece of equipment. The relations have two characteristics: (i) there are various kinds of relations, and (ii) closeness of relations varies by viewpoints. The result of the extraction depends on the relation closeness. Users can check related pieces of equipment by a simple operation selecting another piece of equipment from displayed items and setting a viewpoint. Our experiments show the advantage of this method. The counts of screens shown to check plant status reduced to 40 %, extracted items were appropriate to show, and viewpoints were easy to select.
