DeltaV SIS Overview Inside this topic DeltaV Safety Instrumented Systems DeltaV SIS Hardware DeltaV SIS Software Operating DeltaV SIS DeltaV SIS Documentation (Use Ctrl+F to search this top ic.) A Safety Instrumented System (SIS) is a set of components including sensors, logic solvers, and final control elements whose purpose is to respond to plant conditions, which may be hazardous in themselves, or if no action were taken, could eventually result in a hazardous condition. The Safety Instrumented System must generate the correct outputs to prevent the hazard or reduce the consequences of the hazard. Safety instrumented systems are applied to a process to reduce the risk from costly or dangerous failures in industrial processes. The magnitude of risk reduction needed is determined from an analysis of the severity of hazardous process events and their probability of occurrence. Safety instrumented systems are typically made up of multiple Safety Instrumented Functions (SIFs). Each SIF defines: The measurements (sensors) to use The actions to take (control elements to drive) When to apply the actions (logic linking the measurements to the actions) How fast to measure and react Every SIF has a Safety Integrity Level (SIL) assigned to it. SIL is a measure of the risk reduction provided by a SIF based on four discrete levels, each representing an order of magnitude of risk reduction. DeltaV Safety Instrumented Systems DeltaV Safety Instrumented Systems are the combination of DeltaV hardware and software that you use to install, configure, and operate a system to implement a safety instrumented system in conjunction with sensors and final elements to take a process to a safe state when hazardous conditions occur. DeltaV SIS components are separate from, but integrated with, the DeltaV basic process control system (BPCS). The DeltaV SIS Logic Solvers mount on standard DeltaV I/O backplanes but they are powered separately from the BPCS power supplies. Safety Instrumented Functions are configured in one or more SIS modules using the DeltaV engineering tools—DeltaV Explorer and Control Studio. SIS modules are downloaded to run in Logic Solvers. DeltaV SIS Hardware DeltaV SIS hardware includes the following products: Logic Solvers (SLS 1508) — run the SIS modules you configure. SLS Terminal blocks — for I/O to Logic Solvers. SISNet Repeaters — provide communication between Logic Solvers that are attached to different controllers. Fiber optic cable/ring — SISNet Repeaters connected to one DeltaV Controller communicate with SISNet Repeaters connected to a different controller over a fiber-optic ring. Terminated one-wide carriers — terminate the local peer bus at the final carrier. The following figure shows a schematic diagram of how the DeltaV SIS hardware is connected to a DeltaV control system. 1 of 6 20-Jan-14 07:18 PM 3 http://www.DeltaV Books Online 9.com/bol/mergedprojects/SISMasterBOL/merge..

For detailed information on DeltaV SIS hardware and how it installs in a DeltaV system. the following figure shows DeltaV Explorer after DeltaV SIS has been enabled and some configuration has been completed.

Enabling DeltaV SIS from System Preferences adds SIS objects to the DeltaV Explorer and Control Studio so you can configure DeltaV SIS Logic Solvers and SIS modules. The SIS Network contains the Logic Solvers (SLS1 and SLS2 in the figure). Explorer Hierarchy with DeltaV SIS Enabled The most obvious difference when DeltaV SIS is enabled is the appearance of the SIS Network.4shared. the enhancements to accommodate DeltaV SIS include the addition of the SIS module and template types and a set of SIS palettes.com/doc/g3m_hXhr/preview. The changes appear when creating or editing an SIS module as shown in the following figure.. and secure parameters) that will ultimately be downloaded to a physical Logic Solver card.

The mechanism also requires that the operator confirm the change. 3. please read the DeltaV Getting Started manual to learn how to use the DeltaV engineering tools. In general.

SIS Configuration and Steps to Implement DeltaV SIS . To configure and operate a safety instrumented system with DeltaV SIS you use the same tools used by a DeltaV process control system.4shared.

Features and tasks that are unique to DeltaV SIS or that differ greatly between a basic DeltaV system and DeltaV SIS are explained in full. there are differences between the two. If you need information on basic DeltaV configuration or operation. The DeltaV SIS Safety Manual contains additional information on DeltaV SIS. The DeltaV SIS Safety Manual is distributed on the DeltaV Documentation Library CD..3 http://www.DeltaV Books Online 9.3 http://dc261.easydeltav.. The DeltaV SIS documentation (except the DeltaV SIS Safety Manual) is included as a book within the standard DeltaV Books Online. These differences are explained throughout this book in two different ways: Features and tasks that are similar for both basic DeltaV systems and DeltaV SIS are explained by exception. The DeltaV SIS book contains the information you need to implement and operate a safety instrumented system. this document explains only the differences and refers to the DeltaV documentation for general information. and operate a safety instrumented system with DeltaV SIS are similar to the tasks required to implement a process control system with basic DeltaV systems.com/doc/g3m_hXhr/preview.
