Emerson Process Management's Smart Safety Instrumented System (SIS) uses digital intelligence and diagnostics, from sensor to logic solver to final control, to extend PlantWeb digital plant architecture, and help users implement safer process plants. Automated safety-loop testing and other features in SIS reportedly increase system availability, reduce lifecycle costs, and ease regulatory compliance.

SIS solutions are built from PlantWeb technologies and include intelligent field devices, predictive diagnostics, and digital communications. They implement a safety integrity level (SIL) 3 strategy, which includes transmitters and valve controllers certified to IEC 61508 and SIL3-compliant safety systems. SIS may be integrated with mainstream basic process control systems for facility-wide overview, while maintaining separation of safety-critical elements as required by IEC standards. Safety data and alarms are presented on DeltaV operator interfaces, stored in its historians, and passed to AMS Suite: Intelligent Device Manager software for integrated documentation and management.

SIS also includes DeltaV-based SIS systems that communicate with SIS sensors and final control elements; SIS sensors, including Rosemount's 3051S pressure transmitter and 3144P temperature transmitter; final control elements with partial stroke testing, including SIL-PAC emergency shutdown valves; DeltaV SIS software; and AMS Device Manager software. www.easydeltav.com
