IEC 61968-13:2021 specifies profiles that can be used to exchange Network Models in a Utility or between a Utility and external applications to the utility. This document provides a list of profiles which allow to model balanced and unbalanced distribution networks in order to conduct network analysis (Power flow calculation). Therefore it leverages already existing profiles (IEC 61970-45x based on IEC 61970-301 (CIM base) or profiles based on IEC 61968­11 CIM extension for Distribution). This d...view more

This part of IEC 61000 is applicable to the immunity requirements of electrical and electronic
equipment to radiated electromagnetic energy. It establishes test levels and the required test
procedures.
The object of this document is to establish a common reference for evaluating the immunity of
electrical and electronic equipment when subjected to radiated, radio-frequency
electromagnetic fields. The test method documented in this part of IEC 61000 describes a
consistent method to assess t...

This part of IEC 62541 defines the Information Model of the OPC Unified Architecture. The
Information Model describes standardized Nodes of a Server’s AddressSpace. These Nodes
are standardized types as well as standardized instances used for diagnostics or as entry
points to server-specific Nodes. Thus, the Information Model defines the AddressSpace of an
empty OPC UA Server. However, it is not expected that all Servers will provide all of these
Nodes.

Services defined are the collection of abstract Remote Procedure Calls (RPC) that are
implemented by OPC UA Servers and called by OPC UA Clients. All interactions between
OPC UA Clients and Servers occur via these Services. The defined Services are considered
abstract because no particular RPC mechanism for implementation is defined in this
document. IEC 62541‑6 specifies one or more concrete mappings support...
