Development Of A Standard Gas Measurement Data Model In Scada Systems

In large-scale gas SCADA systems, the variety and extent of field equipment requires a new look at the development of data concentrators, common data models, and broker based messaging for connection to the enterprise. Scanned devices have a limited range of data structures which must be aggregated and normalized to an ‘open’ vendor independent model at the front end of SCADA and MEASUREMENT systems before being applied to general applications and decision support in the enterprise. The development of object technology and brokered messaging systems is now allowing SCADA vendors to flatten architectures and improve interconnection between applications. The adoption of a Common Information Model (CIM) in gas measurement will allow SCADA and MEASUREMENT systems to operate as open peer data sources to the enterprise, yet still retain independence of purpose and ability to grow and evolve separately
