摘要
差错防范措施组合的选用工作和残余差错率的量化工作是现场总线系统功能安全保障活动的重要组成部分。本文以PROFIsafeV2.0协议安全机制为例,介绍了防止典型传输差错的安全措施和通信残余差错率的计算方法,总结了功能安全型网络安全机制设计方法和一般性原则。
The adopted deterministic remedial measures and quantification result of residual error rate are two crucial aspects in functional safety communication profiles＇ evaluation. By enumerating the error control measures, introducing the calculation method of residual error rate and demonstrating the fault prevention measures adopted in the PROFIsafe V2.0, this page presents several considerations for the design of functional safety communication.
