<p>PURPOSE:To obtain a plant data display device which automatically stores graphic data each time an event is generated, displays the graph plural gathered data on the same subsequent coordinate axes, stores the data without operator's operation even when the operator is busy, and facilitates the analysis and recording of subsequent display data. CONSTITUTION:This plant data display device is provided additionally with an automatic event decision means 6 for plant state change judgement as to the process quantity and generated event of a plane, a graphic data gathering event storage device 11 for logic storage which determines in what state of the plane an event is generated, a graphic data gathering event registering means 5 where logic is indicated by the operator through an interaction device 1 and altered or newly registered, an event-time graphic data storage device 14 for graphic display data storage in event generation, and a graphic data storage means 9 which stores the event-time graphic data storage device 14 with the graph data on an event generation time gathered graphic display data storage device 13.</p> |
