<p>PURPOSE:To immediately and certainly call a desired tag without storing the individual tag names of the enormous number of the tags. CONSTITUTION:Plural construction tags constituting a chemical plant are sorted into hierarchical construction and elating construction tag at a higher-order hierarchy (PLANTA) and construction tags belonging to a lower-order hierarchy (REC100, EX100,...) are respectively stored in reference to the respective construction tags(R10, for example). The relating construction tags are successively displayed on a display means from the high-order hierarchy to the lower-order hierarchy. The desired construction tag (REC100) is selected by tracking the displayed construction tags. Then, information relating to element tags (T100, ...) laid to the selected construction tag is displayed on the display means.</p> |
