DeltaV SIS Process Safety System Product Data Sheet June 2016 DeltaV Safety Instrumented System (SIS)™ with Electronic Marshalling Optimized process reliability Simplified safety lifecycle management Flexibility to meet project needs Reduces installed cost of system Field mounted capable hardware Introduction The DeltaV SIS process safety system has a uniquely scalable modular architecture that is based on the CHARMs Smart Logic Solver (CSLS) and the unprecedented flexibility and ease of use of the Emerson Electronic Marshalling solution. Each CSLS provides I/O processing, Safety Integrity Level 3-capable logic solving, and diagnostics in a single logic solver. The CSLS supports up to 96 individually configurable channels, allowing flexibility for implementing safety instrumented functions and is designed specifically for multi-core home run cables or field junction box installation. All communications are completely redundant from the channel (LS CHARM) to the CSLS. Integrated HART® I/O brings field diagnostics into the CSLS. Benefits Optimized process reliability. Emerson has extended the benefits of the PlantWeb® architecture to safety instrumented systems, with DeltaV SIS being a key component of the Smart SIS solution. Research shows that more than 90% of all faults in SIS applications occur in field instruments and final elements. The DeltaV SIS process safety system has the world’s first Smart Logic Solver using LS CHARMs. It communicates with intelligent field devices using the HART protocol to diagnose faults before they cause spurious trips. This approach increases process availability and reduces lifecycle costs. The DeltaV SIS™ process safety system has the world’s first CHARMs Smart SIS Logic Solver, using the power of predictive intelligence to increase the availability of the entire safety instrumented function in combination with the advantages of the Emerson Electronic Marshalling solution. Flexibility to meet project needs. Whether you have an isolated wellhead or a large emergency shutdown (ESD) application, the DeltaV SIS system scales to provide you with the safety coverage you need for your SIL 1, 2 and 3 safety functions. Each CHARMs Smart Logic Solver provides I/O processing, SIL 3-capable logic solving, and diagnostics. This means that processing power is added as the system expands, and no additional processors will ever be required. Scan rate and memory usage are constant and independ

DeltaV SIS with Electronic Marshalling Modularity also provides isolation of safety instrumented functions (SIF). This isolation eliminates single-points of failure for improved availability and safety integrity. The DeltaV SIS system looks for new hardware every scan, so equipment can be added to a running system in real time. Online addition of new logic solvers will not interrupt your process. Simplified safety lifecycle management. The DeltaV SIS CSLSs are SIL 3-rated for both simplex and redundant architectures. Redundant CSLS pairs can be installed for increased process availability of...

DeltaV SIS with Electronic Marshalling The DeltaV SIS SIF-based approach does not mean that all of the safety logic and I/O have to fit into one logic solver. All input data is made available to every logic solver on the LSN every 50 ms the same as the local inputs on every CSLS. June 2016 The health and status of both logic solvers and their channels are available in the Diagnostics Explorer. With DeltaV SIS logic solvers, neither the scan rate nor the execution of a SIF is altered by changes or additions to another SIF. DeltaV SIS logic solvers always execute deterministically, every 50 ms,...

DeltaV SIS with Electronic Marshalling In general, when there is a plant event that triggers an ESD from the SIS, one input will exceed a trip limit on one scan and this will cause outputs to trip and more inputs will then change state. Sequence of Events Recording has been used to find that first input that caused the trip by looking at all of the inputs in the plant. With the DeltaV SIS system, the operator simply filters the Event Chronicle for first-out trips, and the first-out is clearly visible. If higher resolution is required for some channels then they can be wired to both the DeltaV...

DeltaV SIS with Electronic Marshalling Label features are available to identify channel usage and Baseplate identification to help with maintenance. LS CHARMs can be added to any existing base plate position and autosensed online. Additional CSLS can be added online. LS CHARM Types A variety of analog and discrete LS CHARMs are available to meet your specific requirements. The following LS CHARMs are available starting with DeltaV v12.3: LS DI 24 VDC low-side sense (dry contact) All LS CHARMs have a bi-color Power/Integrity LED that indicates the health of the LS CHARM. The indications provide...

DeltaV SIS with Electronic Marshalling The LS Redundant Terminal Block can be used with the Redundant DVC Output LS CHARM type. Refer to specific LS CHARM specifications for wiring information. The LS Redundant DTA Fused Injected Power Terminal Blocks are designed for high output current applications and requires the LS DO 24 VDC Redundant DTA or ETA CHARM to drive the relay coil. The Redundant Relay Output Term blocks provide a normally open and normally closed contact with the following ratings: The Terminal Blocks contain keying posts that are automatically set and locked to the unique position...
