Electricity metering data exchange - The DLMS/COSEM suite - Part 5-3: DLMS/COSEM application layer

IEC 620565-3:2013 specifies the DLMS/COSEM application layer in terms of structure, services and protocols for COSEM clients and servers, and defines how to use the DLMS/COSEM application layer in various communication profiles. It defines services for establishing and releasing application associations, and data communication services for accessing the methods and attributes of COSEM interface objects, defined in IEC 62056-6-2, using either logical name (LN) or short name (SN) referencing. This edition cancels and replaces IEC 62056-53 published in 2006. It constitutes a technical revision.

Échange des données de comptage de l'électricité - La suite DLMS/COSEM - Partie 5-3: Couche application DLMS/COSEM

La CEI 62056-5-3:2013 indique la couche application DLMS/COSEM en termes de structure, de services et de protocoles pour les clients et serveurs COSEM, et définit comment utiliser la couche application DLMS/COSEM dans différents profils de communication. Elle définit les services permettant d'établir et de libérer des associations d'applications, ainsi que les services de communication de données permettant d'accéder aux méthodes et aux attributs des objets d'interface COSEM, définis dans la CEI 62056-6-2, à l'aide du référencement par nom logique (LN) ou par nom abrégé (SN). Cette édition annule et remplace la CEI 62056-53 parue en 2006. Cette édition constitue une révision technique.

Izmenjava podatkov meritev električne energije - Niz DLMS/COSEM - 5-3. del: Aplikacijska plast DLMS/COSEM (IEC 62056-5-3:2013)

Ta del standarda IEC 62056 določa aplikacijsko plast DLMS/COSEM v smislu strukture, storitev in protokolov za odjemalce ter strežnike COSEM in opredeljuje, kako se ta aplikacijska plast uporablja v različnih komunikacijskih profilih. Določa storitve za vzpostavljanje in izdajanje povezav aplikacij in podatkovne komunikacijske storitve za dostop do metod in atributov vmesniških objektov COSEM iz standarda IEC 62056-6-22 z uporabo reference logičnega (LN) ali kratkega imena (SN). Priloga A (normativna) določa, kako se pri različnih komunikacijskih profilih uporablja aplikacijska plast COSEM. Določa, kako so lahko različni komunikacijski profili izdelani za izmenjavo podatkov z opremo za merjenje, ki uporablja vmesniški model COSEM, in kateri so potrebni elementi, ki jih je treba v določiti v vsakem komunikacijskem profilu. Dejanski komunikacijski profili, značilni za medije, so določeni v ločenih delih serije standardov IEC 62056. Priloga B, priloga C, priloga D (informativne) vključujejo primere enkodiranja za aplikacijski protokol APDU. Priloga E (informativna) ponuja pregled kriptografije.
