Annotation of standard text IEC 61131-9-ed.2.0 :
IEC 61131-9:2022 specifies a single-drop digital communication interface technology for small sensors and actuators SDCI (commonly known as IO-Link™ ), which extends the traditional digital input and digital output interfaces as defined in IEC 61131-2 towards a point-to-point communication link for the exchange of complex data in both directions. This techno¬logy also enables the transfer of parameters to Devices and the delivery of identification and diagnostic information from the Devices to the automation system. This technology is mainly intended for use with simple sensors and actuators in factory automation, which include small and cost-effective microcontrollers. This document specifies the SDCI communication services and protocol (physical layer, data link layer and application layer in accordance with the ISO/OSI reference model) for both SDCI Masters and Devices. This document also includes EMC test requirements. This document does not cover communication interfaces or systems incorporating multiple point or multiple drop linkages, or integration of SDCI into higher level systems such as fieldbuses. LIEC 61131-9:2022 specifie une technologie dinterface de communication numerique point a point pour petits capteurs et actionneurs – SDCI – (generalement connue sous lappellation IO-Link™[1]). Elle permet detendre les interfaces classiques dentrees et de sorties numeriques (telles que definies dans lIEC 61131-2) en une liaison de communication point a point pour lechange de donnees complexe dans les deux sens. Cette technologie permet egalement de transferer des parametres aux Dispositifs et de fournir au systeme dautomatisation des informations de diagnostic et didentification depuis les Dispositifs. Cette technologie est principalement destinee a l’utilisation en automatisation dusine avec de simples capteurs et actionneurs integrant de petits microcontroleurs economiques. Le present document specifie les services et le protocole de communication SDCI (couche physique, couche de liaison de donnees et couche Application conformement au modele de reference ISO/OSI) pour les Maitres et Dispositifs SDCI. Le present document inclut egalement des exigences dessai CEM. Le present document ne couvre pas les interfaces ou systemes de communication comportant des connexions multipoints ou a liaisons multiples, ou encore lintegration de SDCI dans des systemes de niveau superieur tels que les bus de terrain.
