Supervisory control and data acquisition (SCADA) is a term used ubiquitously throughout the
automation world. Supervisory control is monitoring and control of plant equipment from a
central location. Data acquisition is the collection and storage of plant data, which is readily
available for plant staff use. In the past, many SCADA system designs were tailored primarily to
customers' monitoring and control needs, and data acquisition was often overlooked. Today,
however, regulatory agencies are establishing stringent requirements on water quality. To meet
these requirements, municipalities are increasingly allocating more resources for automating data
collection and plant report generation.
This paper investigates various technologies and methodologies for data collection, storage, and
reporting. Database packages that are commonly used for data storage, such as Industrial SQL
Server by Wonderware, and the iHistorian by Intellution, are explained. Data collection
methodologies, such as cyclical storage and report-by-exception are discussed. Several
report generation tools, such as SyTech XLReporter and Microsoft Access are presented. The
paper concludes with an explanation of actual reports developed for a municipal water treatment
plant. Includes 8 references, figure.
