Annotation of standard text IEC 61139-2-ed.1.0 :
IEC 61139-2:2022 specifies the extensions to SDCI in IEC 61131-9 for functional safety. This comprises: • a standardized OSSDe interface for redundant switching signals based on IEC 61131-2, • minor modifications/extensions to state machines of SDCI to support the safety operations, • a lean functional safety communication protocol on top of the standard SDCI communication which is a black channel according to IEC 61784-3:2021, • protocol management functions for configuration, parameterization, and commissioning, • IODD extensions for functional safety, • a Device tool interface to support Dedicated Tools according to functional safety standards. This document does not cover: • communication interfaces or systems including multi-point or multi-drop linkages, • communication interfaces or systems including multi-channel or encrypted linkages, • wireless communication interfaces or systems, • integration of SDCI-FS into upper-level systems such as fieldbuses/FSCPs. LIEC 61139-2:2022 specifie les extensions de la SDCI de lIEC 61131-9 pour la securite fonctionnelle. Elle comprend: • une interface OSSDe normalisee pour les signaux de commutation redondants, fondee sur lIEC 61131-2; • des modifications/extensions mineures des diagrammes detats de la SDCI afin de prendre en charge les operations de securite; • un protocole de communication de securite fonctionnelle affine en plus de la communication SDCI normalisee, qui constitue un canal noir selon lIEC 61784-3:2021; • des fonctions de gestion de protocole pour la configuration, le parametrage et la mise en service; • des extensions de lIODD pour la securite fonctionnelle; • une interface doutil dAppareil pour prendre en charge les outils dedies, conformement aux normes de securite fonctionnelle. Le present document ne couvre pas: • les interfaces ou systemes de communication qui incluent des liaisons multipoints; • les interfaces ou systemes de communication qui incluent des liaisons chiffrees ou multicanaux; • les interfaces ou systemes de communication sans fil; • lintegration de la SDCI-FS aux systemes de niveau superieur, tels que les bus de terrain/FSCP.
