Learning Objectives
- Analyze any system technology and configuration to see if it will meet the required SIL
- Determine if existing systems are safe enough (or whether they need to be upgraded) and whether proposed systems will meet the performance requirements
- Explore the LOPA
- Determine the optimum manual test interval for any system, saving your company time and money by not over- or under-testing systems
Topics Covered
- System Modeling/Analysis Hands-On Advanced Examples
- Multiple examples with different field device technologies
- Configurations
- Diagnostic levels
- Test intervals
- Common cause factors
