Voting Configuration Decision Factors

Recording Date: July 2020

Determining the optimal voting configuration for a Safety Instrumented Function (SIF) can be confusing. This webinar will identify some reasons why the SIF voting is not the same as the logic configuration. We will also consider some common sensor and final element configurations and evaluate the impact of voting decisions on the PFDavg and MTTFS. Finally, some tips will be provided to help the end user define the voting for more complex arrangements.
