PlantWeb Smart SIS architecture pioneers the integrated use of digital intelligence to enable customer implementation of safer process plants, using automated safety loop testing

PlantWeb Smart SIS architecture pioneers the integrated use of digital intelligence to enable customer implementation of safer process plants.

Emerson Process Management announces the new PlantWeb Smart SIS safety management architecture that extends the innovations of the proven digital process automation architecture to enable safer process plants and facilities.

First in the industry to employ digital intelligence and diagnostics from sensor-to-'logic solver'-to-final control, and to take an integrated complete safety loop approach, the PlantWeb Smart SIS safety management solution offers automated safety loop testing and other features that increase system availability, while reducing life-cycle costs and easing regulatory compliance.

The new Smart SIS solutions are built from proven PlantWeb technologies - including intelligent field devices, predictive diagnostics, and digital communications - that are already demonstrating their value in thousands of mainstream process automation projects around the world.

For safety applications, PlantWeb Smart SIS solutions provide assurance of a SIL3 approach that includes transmitters and valve controllers certified to IEC61508, and SIL-3 ratified safety systems.

Emerson professional safety personnel and services organisations help customers plan and implement Smart SIS solutions to comply with the new IEC 61511 safety standards.

Expert services include assisting the customer with process hazard analysis and risk assessment along with Smart SIS design, implementation, and commissioning.

Facilitated by PlantWeb technologies, the Smart SIS solutions are easily integrated with mainstream Basic Process Control Systems to enable facility-wide overview, while maintaining separation of safety-critical elements as required by IEC standards.

Safety data and alarms are presented on the Emerson DeltaV operator interfaces, stored in its historians, and passed to the AMS Suite: Intelligent Device Manager for integrated documentation and management.

"The Smart SIS safety management solutions deliver the same ease of use and efficiencies for safety in process facilities as the proven PlantWeb architecture does for mainstream process automation," commented John Berra, president of Emerson Process Management.

"PlantWeb Smart SIS solutions use digital intelligence and automated proof testing, including partial valve stroking, to enable continuous and on-demand diagnosing of safety loop sensors, logic solvers and final control elements to ensure they perform on demand," continued Berra.

"The resulting high reliability of safety systems reduces the risk of plant trips, which keeps our customers up and running.

At the same time, the approach minimises costly and risky practices of ongoing manual proof tests".

Intelligent components that combine to deliver ease of use of PlantWeb Smart SIS safety management solutions include the following.

DeltaV Safety Systems that communicate with safety-certified sensors and final control elements.

This Safety System uses the same engineering tools and interfaces as the Emerson DeltaV digital automation system for process control, enabling the viewing of Safety System data from any control system interface.

Sensors such as the certified Rosemount 3051S pressure and 3144P temperature transmitters, plus other flow and level measurement devices and analysers.

Other sensors will be certified soon and are currently available for SIL 3 safety applications based on "proven in use" experience.

Final Control Elements with partial stroke testing, including SIL-PAC emergency shutdown valves (ESD) comprised of Bettis, Hytork or El-O-Matic actuators and a certified Fisher DVC6000 digital valve controller, combined with any make of valve to offer an integrated and tested unit.

DeltaV Safety System software that includes an exclusive palette of TUV-certified smart function blocks, enabling users to employ simple drag-and-drop techniques to accomplish tasks that required pages of coding in traditional safety systems.

AMS Suite: Intelligent Device Manager software that documents and archives system configuration and all changes, as well as system health information and alarms.
