exSILentia Training Courses

exida has developed courses that will familiarize users with all facets of the exSILentia tool to ensure efficient implementation of the Safety Lifecycle tasks.

exSILentia: SIL Selection and SIL Verification

Attendees will learn how to perform Safety Integrity Level (SIL) Selection and Verification using the advanced capabilities of exSILentia® . This will help users determine the required risk reduction for each hazard scenario and the achieved risk reduction for each identified Safety Instrumented Function (SIF). The class will also cover interfacing with Process Hazard Analysis (PHA) results, documentation of the Safety Requirements Specification (SRS), and operational aspects such as proof testing.

Generating logic using the DeltaV SIS Configurator

Generating logic using the DeltaV SIS Configurator, FSE 246, explains how the exSILentia DeltaV SIS Configurator plug-in is used to generate logic for a DeltaV SIS system. Students will learn how to generate logic for their DeltaV SIS logic solver using their conceptual SIF design information from the SILver™ and the Design SRS modules. This course will review how selections made in exSILentia will impact the logic creation process. It will also provide instruction on generating a cause and effect matrix representing the logic.

Layer of Protection Analysis with LOPAx™ and Safety Requirements Specification with SRS

Layer of Protection Analysis with LOPAx™ and Safety Requirements Specification with SRS, FSE 243, explains how the exSILentia LOPAx™ module is used to conduct a Layer of Protection Analysis and how SIF requirements can be documented using the exSILentia SRS module. This course is targeted towards students that have a general understanding of layer of protection analysis and safety requirements specifications who want to learn how to leverage the advanced features of LOPAx™ and SRS. It will cover how to analyze hazard scenarios considering the frequency of initiating events and the probability of failure for each independent protection layer (IPL) as well as enabling conditions and conditional modifiers. This course will show how to calculate the required Risk Reduction Factor of an IPL and identify Safety Instrumented Functions (SIF). Users will learn how to record mandatory functional and integrity requirements for each SIF. It will teach users how to transfer data from PHAx™ to LOPAx™ as well as from LOPAx™ to SRS.

SIL verification with SILver™

SIL verification with SILver™, FSE 244, explains how the exSILentia SILver™ module is used to perform a SIL verification for Safety Instrumented Functions. Students will learn to leverage the tool to model different SIF architectures ranging from simple 1oo1 configuration to more complex examples. This course also covers review of the key parameters that determine the probability of failure of a SIF as well as minimum hardware fault tolerance and systematic capability aspects. It will show the impact of these parameters on the detailed design, implementation, and operation of the SIF. Furthermore, students will learn how to transfer data from the SILver™ module to the Design SRS module and subsequently complete the Design SRS requirements. Finally, the course covers the impact of proof testing and specification of proof test procedures using the Proof Test Generator module.
