IEC TR 61850-7-510:2021(E), which is a technical report, is intended to provide explanations on how to use the Logical Nodes defined in IEC 61850-7-410 as well as other documents in the IEC 61850 series to model complex control functions in power plants, including variable speed pumped storage power plants. IEC 61850-7-410 introduced the general modelling concepts of IEC 61850 for power plants.…

IEC 62439-2:2021 is applicable to high-availability automation networks based on the ISO/IEC/IEEE 8802-3 (IEEE Std 802.3) (Ethernet) technology. The IEC 62439-2:2021 specifies a recovery protocol based on a ring topology, designed to react deterministically on a single failure of an inter-switch link or switch in the network, under the control of a dedicated media redundancy manager node. The…

IEC 62439-3:2021 specifies two related redundancy protocols that, in the event of failure of any network element, provide seamless switchover with zero recovery time: • PRP (Parallel Redundancy Protocol), which allows attaching nodes to two separate networks while allowing attachment of nodes to one network only; and • HSR (High-availability Seamless Redundancy), which allows threading two-port…

IEC TR 61850-90-14:2021(E), which is a technical report, specifies the information model of devices and functions related to systems of power utility automation, specifically related to FACTS (Flexible AC Transmission Systems) and Power Conversion applications. The IEC 61850-90-14 information model standard utilizes existing IEC 61850-7-4 logical nodes where possible, but also defines specific…

IEC 61850-7-420:2021 defines the IEC 61850 information models to be used in the exchange of information with distributed energy resources (DER) and Distribution Automation (DA) systems. DERs include distribution-connected generation systems, energy storage systems, and controllable loads, as well as facility DER management systems, including aggregated DER, such as plant control systems, facility…

This document specifies the conformance test plan for the 150-Mbit/s coaxial physical layer for MOST (MOST150 cPHY), a synchronous time-division-multiplexing network. This document specifies the basic conformance test measurement methods, relevant for verifying compatibility of networks, nodes, and MOST components with the requirements specified in ISO 21806‑10.

This document specifies the conformance test plan for the 50-Mbit/s balanced media physical layer for MOST (MOST50 bPHY), a synchronous time-division-multiplexing network. This document specifies the basic conformance test measurement methods, relevant for verifying compatibility of networks, nodes, and MOST components with the requirements specified in ISO 21806-12.

This document specifies the conformance test plan (CTP) for the lean application layer for MOST, a synchronous time-division-multiplexing network, as specified in ISO 21806-14. This document specifies conformance test cases (CTCs) for root nodes and remote nodes in the following categories: —    network startup; —    network shutdown; —    network events; —    node discovery; —    connection…

This document specifies the technical requirements for the lean application layer for MOST, a synchronous time-division-multiplexing network. The lean application layer includes a specification of the services available to control the configuration and behaviour of the network management. The lean application layer covers the definition of: —    node kinds, —    node addressing, —    data…

This document describes the communications reference architecture of nodes called "ITS station units" designed for deployment in intelligent transport systems (ITS) communication networks. The ITS station reference architecture is described in an abstract manner. While this document describes a number of ITS station elements, whether or not a particular element is implemented in an ITS…
