SCADA Apparatus for managing realtime tag data in SCADA software and method thereof

摘要

The present invention discloses an apparatus and method for managing real-time tag data in SCADA software. That is, the present invention checks the tags set in a chart group composed of a plurality of tags, checks the name of a column to be used in the database and the bit index occupied in the column, and classifies the tags using the same column into groups for each column. After creating a group, initializing the thermal storage buffer, calculating the thermal storage buffer including the communication status of the tag according to the tag type for each tag included in the thermal group, and storing the calculated thermal storage buffer in the database. When the software saves real-time tag data for historical tag data creation and report generation for historical tag data, it saves disk space by reducing the data capacity, saves time spent reading and writing data from the database, and operating the entire system efficiency can be improved.
