Emerson's DeltaV System Enhanced for Abnormal Situation Prevention

Emerson Process Management released version 8.4 of DeltaV™ system software. Standard HART® device status information can now be used to generate PlantWeb® alerts for any HART device permitting predictive diagnostics that can head off plant abnormal situations. Conditional alarming has been extended to FOUNDATION™ fieldbus devices to make intelligent field devices more discriminating to reduce nuisance alarms.

“Operators need to know when critical field devices are in need of attention and need not be bothered when devices and processes are operating normally,” said Dave Deitz director of marketing for the DeltaV system. “By extending our PlantWeb alerts to HART protocol devices we can alert maintenance and operations personnel to potential trouble areas heading off potential process disruptions. Similarly, by adding conditional alarming to FOUNDATION fieldbus devices it is possible to suppress nuisance alarms that interfere with attention to process operations.” Now the DeltaV controller routes device alerts from HART devices to operators and/or maintenance personnel. This extension of PlantWeb alerts to HART devices is significant for installed base customers who can now take advantage of hidden predictive diagnostics in their installed legion of HART devices” says Dave Deitz. Emerson Process Management intelligent field devices also generate specific error messages making troubleshooting easier. The conditional alarms “on,” “and/or,” or “off” delay time configurations to make devices more responsible to temporary transient conditions reducing the numbers of nuisance alarms.
