Abstract

PURPOSE:To improve a plant monitoring function, by displaying the past time series data, which are stored beforehand when a trend display is requested, and instantaneously providing the change and the trend of the data. CONSTITUTION:When trend registration is requested 2, the request 2 is processed with the following parts: a trend-history registrating means 3, which registers the necessity of trend history; a trend-history storing means 10, which takes out the process data, for which the trend history registration is performed, and stores the data periodically in a trend history file 11; and a history display means 13, which displays the contents of the file 11 on a CRT 14 when the trend display is requested. In this way, the necessity of the trend history is registered beforehand. With respect to the process, which is specified by the trend history data, the data are stored in the file 11 every time the data are updated. The data before the trend display request are displayed 14 by using the data, which are stored in the file 11, in trend displaying. When the trend display is requested, the change and the trend of process data can be instantaneously provided for an operator.
