SIL Implementation on Safety Functions in Mass Transit System [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2018
The concept of Safety Integrity Level (SIL) has been developed within different systems of standards (IEC 61508, EN50129 and DEF-STAN 00-56). These standards are applied in different areas: control technology (IEC 61508), railway technology (EN50128 and ...

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
