A total loop approach tosafetyEmerson’s Smart SIS is theextension of the PlantWebarchitecture to safety instru-mented systems. With integrateddigital communications and devicediagnostics from the sensor, to thelogic solver, to the final controlelement, DeltaV SIS shuts downyour plant when needed for safety,but keeps you running safely whencomponents fail.

Safety instrumented systemsperform a critical role in providingsafer, more reliable processoperations. Based on industryresearch, over 92% of all faults inSIS application occur in fieldinstruments and control elements.Therefore, it is critical to considerthe entire safety instrumentedfunction as a complete entity. As asmart solution, the DeltaV SISsystem continuously monitors the

ability of sensors, logic solvers andfinal elements to perform ondemand while diagnosing faultsbefore they cause spurious trips.Digital HART communications isthe enabler. This approachincreases process availability andreduces lifecycle costs.

Digital transparencyThe PlantWeb digital plantarchitecture enables the use ofdigital intelligence and predictivediagnostics to increase systemavailability while reducing life cyclecosts and enabling easy regulatorycompliance. Emerson products(sensors, systems, and final controlelements) are third-party certifiedto the IEC 61508 standard for usein safety-rated applications.

The DeltaV SIS systemPressure to keep your plant safe 24hours a day, 7 days a week isrelentless. Equipping your safetyinstrumented system with today’sdigital technologies is your bestpath to addressing thisrequirement. A highly reliablesafety system starts withpredictive intelligence, whichprovides a wealth of diagnosticinformation, enabling you topredict and prevent problems before they occur. The DeltaV SISsystem is a comprehensive

solution for your safety system

with the power of embedded digital communications–all day,every day.

Smart logic solverBulky logic solvers and multi-plexers can now be replaced withstate-of-the-art logic solvers thatsupport digital communications tocontinuously monitor the health ofthe entire SIF. The DeltaV SIS logicsolver, built for digital communi-cations with safety sensors andfinal control elements, uses thepower of predictive fieldintelligence to increase the overallreliability of the entire SIF. It is TÜV-certified without exception for usein SIL 1-3 safety applications asdefined by IEC 61508.

An integrated approach to the entire safety instrumented function (SIF)—from sensor, to logic solver, to final control element—shuts down when needed for safety, butkeeps you running safely when components fail.

Smart devices deliverpredictive and healthdiagnosticsBy replacing switches withtransmitters, you take the first steptoward reducing undetectedfailures. Smart transmitters havefar fewer dangerous undetectedfailures than switches. Emerson’ssmart sensors, such as Rosemount TM and Micro MotionTM

devices, go beyond detectingcomponent failures. They evaluatethe performance of the completemeasurement system, extendingdiagnostics to detect formerlyundetectable dangerous failuresoutside the physical bounds of thetransmitter–providing bothtransmitter and processdiagnostics.

The end result is greater credit forfailure-on-demand calculations,easier compliance with IEC 61511guidelines, higher safe failurefractions, less redundancy, lessproof testing and longer intervalsbetween proof tests.

Smart final elementsreduce risk FIELDVUETM digital valve controllerinstruments provide automatedperformance monitoring andtesting by enabling remote partialstroke testing while the safetyvalve is online. This keepspersonnel safely away from thevalve’s location. The FIELDVUEDVC6000 SIS for emergencyshutdown applications is third-party certified for use in SIL 3applications.

FIELDVUE instruments haveextensive diagnostics to monitortravel deviation, pressuredeviation, valve packing frictionand more. Information iscommunicated back to the DeltaVSIS system and the AMSTM DeviceManager software.

The SIL-PAC solution incorporatesEmerson’s industry-leadingactuators, digital valve controllers,solenoids, and valves to provide aSIL 3 certified valve solution:

� BettisTM G and CBA actuators

� FisherTM DVC6000 SIS controllers

� ASCOTM solenoids

� FisherTM valves.

Smart partial stroketesting extends testintervalsAutomated partial stroke testingof valves can improve safetyintegrity, reduce the number ofrisky personnel trips into the field,and extend the time betweenmandatory proof tests. Automatedpartial stroke testing results inincreased confidence that thevalve will perform on demandwhile reducing costs. Partial stroketests can be automatically initiatedby the DeltaV SIS logic solver ormanually initiated from standardoperator faceplates. The DeltaV SISsystem communicates with theDVC6000 SIS via the HARTprotocol so no additional wiring orcomponents are required toautomate partial stroke tests.Partial stroke test results areautomatically recorded in theDeltaV Event Chronicle for easydocumentation.

The unique, modular distributedarchitecture enables you tocustom fit the system for your SISapplications. Modularity gives youthe flexibility to meet changingproject requirements. The DeltaVSIS architecture is flexible to helpprovide the safety you want, whenyou want, where you want.

Applications that require safetyinstrumented systems to reducerisk come in all sizes andtopologies. You need anSIS offering that can handle thesmallest to the largest applicationand one that has the flexibility toaddress widely distributedarchitectures. The modular SIF-based DeltaV SIS architecturedelivers the capability to meetchanging project requirements.

Flexible architectureWhether you have an isolatedboiler or a large ESD application,the DeltaV SIS system scales tohelp provide the safety coverageyou require for your SIL 1, 2 and 3applications. Unlike otherapproaches, the modular logicsolver hardware scales in sizes of16 configurable I/O. This meansyou automatically add memoryand logic solver processing everytime you add I/O. The days ofrunning out of memory orprocessing power are over.

A SIF-based approachThe DeltaV SIS architecture allowsyou to concentrate on the designof each SIF–each logic solver is acontainer for a small number ofSIFs and there can be nounplanned interaction betweenthem. This is very different from

the traditional approach wherehundreds of SIFs are all placed in asingle safety PLC and the effect ofchanging a single register or theaddition of a SIF could affect all ofthe logic. The DeltaV SISarchitecture isolates SIFs,eliminates single points of failure,and simplifies change manage-ment. For complex applications,which require multiple SIFs actingon the same final element, inputdata is shared among multiplelogic solvers so that cause andeffect logic can easily beimplemented in a single SISmodule.

Given this flexibility, the DeltaV SISsystem is ideally suited for allsafety applications up to SIL 3:from small burner managementapplications to large ESD and fireand gas applications.

Flexible to provide the safety you want, when you want, where you want.

Mitigate theconsequences of eventswhen they occur

IEC 61511 recognizes fire and gassystems (FGS) as mitigative SISsystems. The major focus of a FGSis to mitigate an incident AFTER ithas occurred. This is done to gaintime for people to evacuate thearea, contain the incident fromescalating and allow emergencyresponse teams to assess and dealwith the incident. By monitoringprocess areas where fire, build upof a potentially flammable gas ortoxic gases may occur, the DeltaVSIS system can be configured todetect these hazardous events,alert personnel and initiate timelyactions in order to minimize theconsequences of an incident.

Fire and gas systems are usuallystand alone systems that takeactions when required. Withtoday’s technology, manycompanies utilize an integratedapproach and interface the FGSwith the ESD system to initiateplant shutdown if hazardousevents occur.

The integrated system can alertpersonnel in a fast, accurate andstructured way, giving employeestime to decide what course ofaction to take while bringing theplant to a pre-determined state.

Permit the system tooperate when safe

The DeltaV SIS system can be usedfor burner management system(BMS) applications, a safetysolution for control andmonitoring of burner units.Through proper sequencing andinterlocks, the DeltaV SIS BMSapplication allows the burnerunit(s) to go safely through allrelevant states, from start-up tooperation and shutdown whenneeded. If so required (usuallydependent on the size of theburner unit), the DeltaV SIS systemcan also be configured to provideautomated leak testing of the gasvalves. Using specially developedfunction blocks, the DeltaV SISBMS solution is highly flexible andeasy to maintain and monitor.
