Emerson announces machine diagnostics developments based on the EDDL standard

25 October 2006

Based on enhancements to the international standard Electronic Device Description Language (EDDL), Emerson Process Management has introduced EDDL enhancements into its motor-pump monitoring technology, the CSI 9210 Machinery Health Transmitter. The CSI 9210 is a key member of a range of field devices and valves from Emerson that power its PlantWeb digital plant architecture to reduce capital project costs and improve operations efficiency.

The CSI 9210 acquires vibration, temperature, motor flux, and machine speed on AC motor-pump machine trains, analyses the measured data, calculates machinery health, issues alerts if necessary, and recommends action to be taken. With these recent interoperable EDDL improvements, end users now have improved access to details surrounding the analysis results, thus enabling them to make even better operational decisions.

Emerson recently announced a move towards the enhanced EDDL interface for its field devices and valves, which will drive new displays that use familiar dialogue boxes to present graphs, charts, and trending of dynamic variables in addition to text, and archived data in a consistent, familiar format.

“EDDL enhancements lend themselves very well to the types of information people have asked to see from the CSI 9210, and Emerson is committed to delivering what our customers need,” said Brian Humes, general manager of Emerson’s Machinery Health Management business. “The new EDDL interface provides a clearer, visually-intuitive picture of developing cavitation – plus it is interoperable.”

“For example, enhanced graphics can clearly show when the pump has exceeded the Maintenance Threshold for cavitation, as indicated by displaying a bar graph, as well as in the graphic of the pump itself,” continued Humes. “As cavitation continues to increase, we see all three graphical elements change to reflect the pump moving into the Failed Threshold. Also, spectrum data associated with the cavitation is presented, along with recommendations for correcting the situation before actual failure occurs.”

Sophisticated devices with hundreds of configuration, calibration, and diagnostic parameters such as control valves, radar level gauges, and variable frequency drives will greatly benefit from the new user interface enhancements. EDDL is the only common technology endorsed by the Fieldbus Foundation, HART Communication Foundation, Profibus Nutzerorganisation e.V. (PNO), and OPC Foundation. The interoperability of the language gives users the freedom to choose best-in-class automation products from the suppliers of choice, knowing devices and hosts will work fully and seamlessly together.
