Calculation of the Dangerous Failure Rate of the Safety Function

open access: yesApplied Sciences, 2022
Each safety-related function must be implemented with a defined safety integrity level (SIL) if the control system implements safety-related functions (SFs) in addition to the standard control functions. The required SIL of the SF depends on the quantity
