Smart SIS. Optimized diagnostics for the entire safety loopDeltaV SIS provides an integrated,constant monitoring approach forthe complete safety loop–fromsensor, to logic solver, to finalcontrol element. A keycomponent of Emerson’s SmartSIS is to detect field device failuresbefore they cause spurious trips.
The modern, scalable architectureis based on the CHARMs SmartLogic Solver (CSLS) whichsimplifies the design, installation,wiring and commissioning of anySIS project. This modularity givesyou the capability to meet
changing project requirementsand the flexibility to implementsafety functions easily, and safelywhile eliminating re-work and re-design associated with traditionalmarshalling.
As a standalone safety system,DeltaV SIS can easily beintegrated with control systemsfrom other vendors usinginterfaces that are based on opencommunication standards, suchas Modbus, OPC and OPC.Net.
The DeltaV SIS and DeltaV systemsare integrated noticeably in thesame engineering, maintenance,and operations environment. Allsafety-related information is easilyaccessible through familiar andintuitive applications.
The integrated yet separatearchitecture meets IEC 61508 andIEC 61511 requirements forphysical separation andindependence of safety andcontrol. DeltaV SIS delivers thebenefits of DeltaV integration andseparation without the tradeoffsassociated with the two extremes.

Safety applications are designed toprotect your plant and personnelfrom hazardous conditions andprovide a rapid and coordinatedoperational response toemergency situations.
But with traditional safety systems,once it’s installed and validated,your plant’s safety integrity levelquickly begins to decline as loopsare not called upon regularlyenough to ensure all devices arefunctioning as they should. Atraditional safety system may notknow for months or longer that avalve is stuck.
The modern DeltaV SIS continuallymonitors the health of the entiresafety loop. It takes into accountdevices’ predicted lifespan andpre-empts end of lifecycle withmaintenance notifications andtesting that can be initiatedautomatically by the DeltaV SISlogic solver, or manually from
operator faceplates. The result isyour SIS integrity level stays at astable level longer, extending thetime between full proof tests.
The DeltaV SIS ensures highreliability and availability throughredundant architecture design,including redundant networks,logic solvers and I/O. The systemroutinely monitors, controls andcollects safety-related data forESD, FGS and BMS applications.
Prevent incidents fromoccurring The DeltaV SIS has been widelyused for emergency shutdownapplications to prevent hazardoussituations from occurring, and caninitiate the shutdown of a plant,unit, or piece of equipment should it be required. Sensors are used to
detect certain conditions, and theDeltaV SIS logic solver isconfigured to meet your safetyrequirements to take your plant toa safe state, by manipulating therequired final elements (valves,pumps).
The combination of sensor, logicsolver and final element form asafety instrumented function (SIF).Each SIF is designed to prevent aspecific hazard from occurring byreducing a certain amount of risk.This risk reduction equates to asafety integrity level (SIL). TheDeltaV SIS modern systemprovides SIL 3 reliability incompliance with IEC 61508 and IEC61511 international standards,and in addition has manyinnovations: repeat confirmationbuilt into the operator graphics,

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, DeltaV SIScan detect these hazardousevents, alert personnel and initiatetimely actions in order to minimizethe consequences of an incident.
Fire and gas systems are usuallystandalone systems that takeactions when required. Withtoday’s technology, manycompanies use an integratedapproach and interface the FGS
with 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
DeltaV SIS has been used forburner management system (BMS)applications, a safety solution tocontrol and monitor 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.

A modern approach tosafetyWith integrated digitalcommunications 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 whennon-critical components 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, DeltaV SIScontinuously monitors the abilityof sensors, logic solvers and final
elements to perform on demandby diagnosing faults before theycause spurious trips or fail toperform. Digital HART®
communications is the enabler.This approach increases processavailability and reduces lifecycle costs.
24/7 SafetyPressure 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. DeltaV SIS is acomprehensive solution for yoursafety system with the power ofembedded digital communi-cations–all day, every day.
Smart logic solverBulky multiplexers with traditionallogic solvers can now be replacedwith state-of-the-art logic solversthat support digitalcommunications to continuouslymonitor the health of the entireSIF. The DeltaV SIS logic solver,built for digital communicationswith safety sensors and finalcontrol elements, uses the powerof predictive field intelligence to
increase the overall reliability ofthe entire SIF. It is TÜV-certified foruse in all SIL 1, SIL 2 and SIL 3 safetyapplications as defined by IEC 61508.
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.
Because safety systems are designed to perform only when an abnormalsituation occurs, how to make sure it will perform reliably when needed?

KNOW THE HEALTH OF YOUR SAFETY LOOPS–24/7
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 partial stroketesting extends testintervalsPartial stroke testing of valves canimprove safety integrity andextend the time betweenmandatory proof-tests. Partialstroke testing results in increasedconfidence that the valve willperform on demand whilereducing costs. Partial stroke testscan be automatically initiated bythe DeltaV SIS logic solver ormanually initiated from standardoperator faceplates. The DeltaV SISsystem communicates with theDVC6000 series SIS via the HARTprotocol so no additional wiring or
components are required toautomate partial stroke tests. Partial stroke test results areautomatically recorded in theDeltaV Event Chronicle for easydocumentation.

The modern DeltaV SIS builds inunprecedented flexibility so youcan evolve your safety systemconfidently and cost-effectively. It does this with electronicmarshalling and CHARMtechnologies, which let youseparate safety loop installationfrom logic configuration. Thatmeans you can start hardware design earlier in the engineeringprocess–before HazOps completion.
These technologies weredeveloped in response tocustomers with moving offshoreoil platforms where home runwiring means crucial added weightas well as high installation costs,(and every square inch ofautomation system footprint isseverely limited). Electronicmarshalling lets you land wholegroups of safety loops in nearbyfield enclosures, running aredundant Ethernet cable to the controller.
Footprint constraints with layers ofpast configuration loopsabandoned in place are noproblem. Simply re-connect theexisting wiring from active loops toa single CHARMs base plate in anyorder or configuration, and you’llactually create extra space for lateruse. Move traditional I/O into fieldenclosures closer to fieldinstruments–landing wires wherethey fit best–regardless of theirI/O type. CHARMs I/O take upabout ¹/³ the space of traditionalI/O and marshalling cabinets.
Applications that require safetyinstrumented systems to reducerisk come in all sizes. You need anSIS that can handle the smallest tothe largest application and theflexibility to address widelydistributed architectures.
Flexible architectureThe 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 need, whenand where you need it.
Whether you have an isolatedboiler or a large ESD application,the DeltaV SIS system scales toprovide the safety coverage yourequire for your SIL 1, SIL 2 and SIL 3 applications.
Modifications or additions to your control system can mean excessive engineeringre-work to your safety system. And with demanding standards and regulations, verifying those changes can be complex and time-consuming.

Lower your risks with amodern safety system:
The modern DeltaV SIS certified,pre-configured function blockssimplify SIS applicationimplementation. No custom codeis required to implement SIS taskswith the IEC 61508-certifiedfunction blocks, providing fasterconfiguration and troubleshootingof SIS logic.
Standard operator faceplatesautomatically provide detailedsafety information with noconfiguration. Using thesefunction blocks can help eliminateengineering hours previouslyneeded to implement ESD, FGS,and BMS applications. Thecertified function blocks deliverpowerful functionality out of thebox, simplifying the imple-mentation of complex SIS applications.
Intuitive safety softwarefunctionsThe DeltaV SIS provides a fullpalette of smart safety functionblocks certified by TÜV for safetyapplications. Special blocks like
voter blocks with bypassmanagement reduce what used tobe pages and pages of ladder logicor custom programming toengineer, test, and commissioninto a simple drag-and-dropconfiguration activity. Usingstandard function blocks insteadof custom programming makes iteasy for engineers to troubleshootand maintain logic, even if they didnot create it.
Voter function blocksVoter function blocks provideadvanced features like built-inbypass and deviation alarms toimprove plant safety. The voting isconfigured to ensure the sameapproach is taken throughout theconfiguration, regardless of theapplication size.
Voter blocks include advancedfeatures such as maintenance andstartup bypasses with a variety of options to meet yourapplication needs.
Cause-and-effectfunction blocksTraditional SIS projectrequirements are typicallydetailed using cause-and-effect matrices (CEM). Onceapproved, these are oftentranslated into logicdiagrams and ultimatelyinto ladder logic.
No more. With the CEM functionblock, the cause-and-effectdiagrams can be deployed directlyin the logic solver, enabling fastconfiguration and reduced testing.The CEM table executes as it ispresented, making documen-tation easy.
CEM function blocks includeadvanced functionality to handletrip status, resetting and forcing of outputs.
With traditional SIS, initial configuration requires extensive customization andany change in process design means extensive rework. And testingDeltaV SIS makes it easier.

Discover the Benefits:
Certified for use in SIL3applications withoutrestriction.Modern DeltaV SIS is built for IEC61511 to simplify regulatorycompliance, with documentationtools that can eliminate risk oferror and improper imple-mentation. DeltaV SIS providesstringent change management,asset management, securitymanagement and documentationcontrol. The system is built fromthe ground up to simplifyregulatory compliance.
Change ManagementIncreasingly stringent regulationsrequire manufacturers to providecomprehensive documentation oftheir process. DeltaV SIS VersionControl and Audit Trail (VCAT) is apowerful tool that tracks changesand manages revision informationfor any item in the configurationdatabase. This application createsand maintains a change history forconfiguration items, such as SISmodules, user accounts andoperator graphics–makingregulatory compliance simpler.
Protected composite templates For reduced complexity in globalengineering and IEC 61508compliance, the DeltaV SIS systemincludes protected compositetemplates. Templates, such ascertified safety logic, are created
on a ‘master’ DeltaV SIS systemand then distributed toengineering centers forimplementation. The templatesare protected from modificationby only allowing changes to occuron the master system.
Easy to track changesComprehensive version control ofa configuration item isautomatically tracked andupdated. The new version is time-stamped and a history commentcan be recorded when the item ischecked back in. Embeddedreporting tools give engineers theability to print configuration
change histories for any item in theconfiguration database.
By keeping detailed historical information on configurationitems, the system automaticallymaintains data for regulatorycompliance requirements andtroubleshooting.
Ensure authorized configurationchangesThe DeltaV SIS security systemgives you the ability to grantprivileges to individual users. Itemsmay be checked out for editingonly by approved users.
Change management of your traditional SIS is expensive, complex, andintroduces risk of error–errors that ripple through your documentation.

Certified safety expertsIEC 61511 requires personnel andorganizations to be competentand qualified to carry out safety activities.
Emerson has committed theresources to become the firstsafety systems provider to developTÜV-certified procedures inalignment with IEC 61511. Inaddition, all employees involvedwith safety system engineeringand development are required tocomplete extensive safety trainingand Emerson certification.
Many of our engineers andtechnologists have also completeda rigorous competencyqualification for system designengineers known as the CertifiedFunctional Safety Expert (CFSE)
exam. This certification requires aminimum amount of experience insafety instrumented systems (SIS)field, as well as successfulcompletion of a comprehensiveexamination.
Reducing failures fromthe startReducing random hardwarefailures and reducing systematicfailures are what IEC 61511 is allabout. Having CFSE expertsinvolved early in the process helpsensure that systematic faults,caused by poor specifications orpoor engineering, are reduced.This is critical because 80% of allSIS-related failures can beattributed to design andimplementation errors. Omissionsin the design of a safety loop orsafety instrumented functions(SIF) could remain undiscovereduntil an incident occurs.
