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.

Smart Logic Solver Knows Health of Field Devices and Manages Valve Testing

The DeltaV Safety System uses digital communications and the smart diagnostics within field devices to increase the availability of the overall safety management solution.  Scheduled partial-stroke testing of final control elements can improve the safety level, reduce the number of risky personnel trips into the field, and increase the mandatory proof test interval.

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 IEC 61508, and SIL3 ratified safety systems.

Emerson professional safety personnel and services organizations 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.

Integrated but separate

With a DeltaV digital automation system as your basic process control system, choosing a DeltaV Safety System provides the integrated engineering and operating environment you've always wanted - while maintaining separation of safety-critical elements as required by IEC standards.

Integration with other systems or applications is also available using OPC or Modbus.

Flexible architecture for any size

Whether you have an isolated boiler or a large ESD application, the DeltaV Safety System can provide the safety coverage you require. The modular logic solver hardware scales in sizes of 16 configurable I/O, so you automatically add memory and CPU every time you add a logic solver. The days of running out of memory or CPU power are over.
