- Link safety functions to LOPA scenarios
- Identify safety critical instrumentation with linked risk scenario data
- Automate incorporation of design checklists during system identification/design
- Configure, build, edit and view SRSs
- Track SRS completion with automated completion KPI
- Build instrumented system architectures with sensor/final element voting structures
- Execute SIL calculations on instrumented systems with SLM’s TUV-certified SIL Calc engine
- Evaluate SIL calculation results from multiple failure rate sources at once
- Utilize prior use component failure rates in the SIL calculations from compiled event data in SLM’s Operate/Maintain module
- Optimize system component testing requirements with sensitivity graphs
- Compare SIL calculation results with calculated target requirements from risk scenario data
- Render the system’s architecture in a function diagram displaying logical view of the system’s sensor and final element voting
- Save well-designed systems as templates to use in other operational areas
- Generate cause & effect matrices automatically from designed instrumented system

Frequently Asked Questions
Does the SLM® system include Checklists for assessments to be completed?
Yes, the SLM system includes over 70 standard checklists. The SLM® system Administrators can add new checklist to any object or object type in the System Module. The SLM® system also has reporting capabilities to track completion progress of any checklists.
Does the SLM® system include Safety Integrity Level (SIL) Calculations
Yes, the SLM® system uses TÜV certi ed IEC61511 compliant fault tree calculation methodology which allows for very complex calculations and SIF modeling with a few clicks of a button.
Does the SLM® system allow tracking of elements not used in the SIL Calculation?
Yes, the SRS allow modeling of inputs and outputs that are not part of the SIL calculation to allow for a complete architecture and automatic generation of complete C&E matrices.
Does the SLM® system allow creation of Cause & Effect Matrices?
Yes, users can quickly create C&E matrices. the SLM® system o ers the below functionality for C&E
