Communication networks and systems for power utility automation - Part 90-30: IEC 61850 Function Mod...
IEC TR 61850-90-30:2025, which is a Technical Report, describes extensions of the SCL Substation/Process Section allowing the creation of a comprehensive, IED and hardware independent specification of an IEC 61850 based power system.
It addresses how to:
• decompose functions in SCL
• show function classifications in SCL
• relate functions with the SCL Substation and Process Section
• relate…
Communication networks and systems for power utility automation - Part 7-6: Guideline for definition...
IEC TR 61850-7-6:2024, which is a Technical Report, is focused on building application / function profiles and specifies a methodology to define Basic Application Profiles (BAPs), in textual documents (edition 1, 2019) or in a machine processable SCL format (current edition). These Basic Application Profiles provide a framework for interoperable interaction within or between typical substation…
Road vehicles — Controller area network (CAN) — Part 1: Data link layer and physical coding sublayer
This document specifies the controller area network (CAN) data link layer (DLL) and the physical coding sub-layer (PCS). The CAN DLL features data fields of up to 2048 byte when the CAN extended data field length (XL) frame format is used.
This document divides the CAN DLL into the logical link control (LLC) and the medium access control (MAC) sub-layers. The DLL’s service data unit (SDU), which…
Blockchain and distributed ledger technologies — Data flow models for blockchain and DLT use cases
This document uses a set of models that describe the flows of different types of data between distributed ledger technologies (DLT) and related systems, as well as between different DLT nodes.
It provides a descriptive analysis of data flows in the development of use cases, as well as the basis for understanding the characteristics of DLT data flows, to support DLT application design and system…
Communication networks and systems for power utility automation - Part 90-27: Use of IEC 61850 for t...
IEC TR 61850-90-27:2023, which is a Technical Report, is to provide basic aspects that need to be considered when using IEC 61850 for information exchange between systems and components to support applications for thermal systems connected to electric power networks. Thermal systems isolated from electric power networks are outside the scope of this document.
From the perspective of category,…
Industrial communication networks - Fieldbus specifications - Part 4-21: Data-link layer protocol sp...
IEC 61158-4-21:2023 describes:
procedures for the timely transfer of data and control information from one data link user entity to a peer user entity, and among the data link entities forming the distributed data link service provider;
procedures for giving communication opportunities based on ISO/IEC/IEEE 8802‑3 MAC, with provisions for nodes to be added or removed during normal operation;…
Industrial communication networks - Fieldbus specifications - Part 4-24: Data-link layer protocol sp...
IEC 61158-4-24:2023 provides
procedures for the timely transfer of data and control information from one data-link user entity to a peer user entity, and among the data-link entities forming the distributed datalink service provider;
procedures for giving communications opportunities to all participating DL-entities (DLEs), sequentially and in a cyclic manner for deterministic and synchronized…

Information technology — Open systems interconnection — Part 1: Object identifier resolution system
This document specifies the OID resolution system, including the overall architecture and a DNS-based resolution mechanism.
It specifies the means for inserting any application-defined information associated with an OID node into the DNS (see clause 6) and the means of retrieval of that information using the ORS (see clause 7).
It does not restrict the number of applications it can support.
It…
