SELF-PACED: FSE 344 Advanced SIL Verification with exSILentia®

exida offers convenient self-paced online training for those wanting to take their courses remotely.

Course Description

FSE 344: Advanced SIL Verification with exSILentia® is an advanced-level course designed for experienced users who want to expand their ability to model and evaluate complex Safety Instrumented Functions (SIFs) using the exSILentia® SILver tool.

Building on the concepts introduced in FSE 244, this course explores the advanced modeling techniques required for SIF configurations that cannot be adequately represented using standard device and architecture models. Participants gain a deeper understanding of the reliability modeling principles used by SILver, including Markov Models, probability of failure on demand (PFD), proof testing, and redundant architectures.

The course then applies these concepts to practical advanced modeling scenarios within exSILentia®. Topics include creating advanced User Defined Devices, configuring custom logic solvers with the Logic Solver Builder, developing Advanced User Defined Logic Solvers, and modeling SIFs containing multiple logic solvers. Participants also explore specialized applications including relay logic and batch operation.

Through detailed examples and practical modeling techniques, participants learn how to represent more complex real-world SIS architectures while understanding how modeling decisions, proof testing, failure rates, redundancy, and equipment configurations affect SIL verification results.

Key Topics

Participants will explore:

• Markov Models in SILver, including transition matrices, state vectors, PFDAVG calculations, safe failures, proof testing, and redundant architectures.
• Advanced User Defined Devices for representing equipment and configurations that require customized reliability parameters.
• Logic Solver Builder techniques for developing more detailed logic solver models.
• Advanced User Defined Logic Solvers, including configuration of CPU, power supply, switch, I/O, and individual channel modules.
• SIFs with multiple logic solvers, including scenarios involving package PLCs interfacing with a plant Safety PLC.
• Relay logic modeling for advanced SIF applications.
• Batch operation modeling for applications that do not fit standard continuous-operation assumptions. 

Prerequisite

Participants should have a good understanding of FSE 244: SIL Verification with exSILentia®. FSE 244 provides the foundation in SILver parameters and detailed SIF modeling upon which FSE 344 builds.

FSE 344 is best suited for:

• • Functional safety engineers
  • SIS engineers and designers
  • Process safety professionals
  • Reliability engineers
  • exSILentia® SILver users
  • Engineers responsible for detailed SIL verification of complex Safety Instrumented Functions
