Electricity metering data exchange - The DLMS®/COSEM suite - Part 5-3: DLMS®/COSEM application layer
This part of IEC 62056 specifies the DLMS®/COSEM application layer in terms of structure, services and protocols for DLMS®/COSEM clients and servers, and defines rules to specify the DLMS®/COSEM 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 62056-6-2:2021 using either logical name (LN) or short name (SN) referencing. Annex A (normative) defines how to use the COSEM application layer in various communication profiles. It specifies how various communication profiles can be constructed for exchanging data with metering equipment using the COSEM interface model, and what are the necessary elements to specify in each communication profile. The actual, media-specific communication profiles are specified in separate parts of the IEC 62056 series. Annex B (normative) specifies the SMS short wrapper. Annex C (normative) specifies the gateway protocol. Annex D, Annex E and Annex F (informative) include encoding examples for APDUs. Annex G (normative) provides NSA Suite B elliptic curves and domain parameters. Annex H (informative) provides an example of an End entity signature certificate using P-256 signed with P-256. Annex I (normative) specifies the use of key agreement schemes in DLMS®/COSEM. Annex J (informative) provides examples of exchanging protected xDLMS APDUs between a third party and a server. Annex K (informative) lists the main technical changes in this edition of the standard.

IEC 62056-5-3:2023 spécifie la couche application DLMS®/COSEM concernant la structure, les services et les protocoles pour les clients et serveurs DLMS®/COSEM, et définit les règles de spécification des profils de communication DLMS®/COSEM. 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 l’IEC 62056-6-2:2021, à l’aide du référencement par nom logique (LN, Logical Name) ou par nom abrégé (SN, Short Name). L’Annexe A (normative) définit comment utiliser la couche application COSEM dans différents profils de communication. Elle indique comment différents profils de communication peuvent être construits de sorte à échanger des données avec le matériel de comptage à l’aide du modèle d’interface COSEM, ainsi que les éléments nécessaires à indiquer dans chaque profil de communication. Les profils de communication réels, spécifiques au support, sont spécifiés dans des parties distinctes de la série IEC 62056. L’Annexe B (normative) spécifie la couche d’adaptation réduite pour le système de messages courts (SMS, Short Message Service). L’Annexe C (normative) spécifie le protocole de passerelle. L’Annexe D, l’Annexe E et l’Annexe F (informatives) incluent des exemples de codage d’APDU. L’Annexe G (normative) spécifie des courbes elliptiques et des paramètres de domaine de la Suite B de la NSA. L’Annexe H (informative) donne un exemple de certificat de signature d’entité finale utilisant P-256 signé avec P-256. L’Annexe I (normative) spécifie l’utilisation de mécanismes d’agrément de clé dans DLMS®/COSEM. L’Annexe J (informative) donne des exemples d’échanges d’APDU xDLMS protégés entre une tierce partie et un serveur. L’Annexe K (informative) énumère les modifications techniques majeures contenues dans cette quatrième édition. Cette quatrième édition annule et remplace la troisième édition parue en 2017. Cette édition constitue une révision technique. Les modifications techniques majeures par rapport à l’édition précédente sont énumérées à l’Annexe K (informative)
Izmenjava podatkov pri merjenju električne energije - Niz DLMS/COSEM - 5-3. del: Aplikacijska plast DLMS/COSEM (IEC 62056-5-3:2023)
Ta del standarda IEC 62056 določa aplikacijsko plast DLMS/COSEM v smislu strukture, storitev in protokolov za odjemalce ter strežnike DLMS®/COSEM in opredeljuje pravila za določanje komunikacijskih profilov DLMS®/COSEM.
Določa storitve za vzpostavljanje in izdajanje povezav aplikacij ter podatkovne komunikacijske storitve za dostop do metod in atributov vmesniških objektov COSEM iz standarda IEC 62056-6-2:2021 z uporabo reference logičnega (LN) ali kratkega imena (SN).
Dodatek A (normativni) opredeljuje, 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 določiti v posameznem komunikacijskem profilu. Dejanski komunikacijski profili, ki se uporabljajo za medije, so opredeljeni v ločenih delih skupine standardov IEC 62056.
Dodatek B (normativni) določa kratko ovojnico za SMS.
Dodatek C (normativni) določa usmerjevalni protokol.
Dodatki D, E in F (informativni) vključujejo primere kodiranja za podatkovne enote aplikacijskega protokola (APDU).
Dodatek G (normativni) podaja eliptične krivulje NSA Suite B in domenske parametre.
Dodatek H (informativni) podaja primer certifikata podpisa končne entitete, ki uporablja krivuljo P-256 in je z njo tudi podpisan.
Dodatek I (normativni) določa uporabo shem za določanje ključa v okviru specifikacije DLMS®/COSEM.
Dodatek J (informativni) podaja primere izmenjave zaščitenih podatkovnih enot APDU xDLMS med tretjo osebo in strežnikom.
