Scalable Solution
exSILentia can be scaled to fit your project and budget needs.
Users
Licensing is based on the number of users using the software concurrently.
No Limits
For each license, there are no limits to the number of projects analyzed. Each project can have an infinite number of SIFs identified, modelled, and monitored making it the most cost effective solution.

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.
FSE 242 - Process Hazard Analysis with PHAx
Process Hazard Analysis with PHAx™, FSE 242, details how the exSILentia PHAx™ module can be used to conduct HAZOP methodology based Process Hazard Analysis. This course is targeted towards students that are experienced in process hazard analysis who want to learn how to leverage the advanced features of PHAx™. It will cover how to configure a project, define risk criteria, and use the advanced libraries to store valuable project specific information. The students will learn how to define units, nodes, and how to benefit from the PHAx™ smart deviations. It also addresses how hazard scenarios are to be defined for use in subsequent lifecycle phases.
FSE 243 - Layer of Protection Analysis with exSILentia®
FSE 243 explains how the exSILentia LOPAx™ module is used to conduct a Layer of Protection Analysis. 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™. 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). It will teach users how to transfer data from PHAx™ to LOPAx™.
FSE 244 - SIL verification with exSILentia
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.
