Precision Clock Synchronization Protocol for Networked Measurement and Control Systems

Precision Clock Synchronization Protocol for Networked Measurement and Control Systems

IEC 61588:2021 defines a network protocol, the Precision Time Protocol (PTP), enabling accurate and precise synchronization of the real-time clocks of devices in networked distributed systems. The protocol is applicable to systems where devices communicate via networks, including Ethernet. The standard allows multicast communication, unicast communication or both. The standard specifies requirements for mapping the protocol to specific network implementations and defines such mappings, including User Datagram Protocol (UDP)/Internet Protocol (IP versions 4 and 6), and layer-2 IEEE 802.3 Ethernet.

Dynamic modules - Part 6-2: Design guide - Software and hardware interfaces - Survey results

IEC/TR 62343-6-2:2013(E) clarifies dynamic module interfaces, which should be standardized, based on the surveys. Annex A is a summary of survey responses by region and Annex B provides survey results specific to the optical channel monitor (OCM). The object of this technical report is to propose a software and hardware interface standard of dynamic modules. The dynamic modules addressed are defined in the IEC 62343 series. This second edition cancels and replaces the first edition published in 2009. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- the survey results of the software and hardware interface of OCM have been added as Annex B, which was presented at the IEC Seattle meeting in 2010. The results are in agreement with the general conclusion of the first edition;
- OPMON (optical performance monitor) in the body of the text has been changed to OCM (optical channel monitor) for consistency with the latest definitions. Keywords: software and hardware interface standard of dynamic modules

Conductors of insulated cables

IEC 60228:2023 specifies the nominal cross-sectional areas, in the range 0,5 mm2 to 3 500 mm2, for conductors in electric power cables and cords of a wide range of types. Requirements for numbers and sizes of wires and resistance values are also included. These conductors include solid, stranded and Milliken, copper, aluminium and aluminium alloy conductors in cables for fixed installations and flexible copper conductors. This document does not apply to conductors for telecommunication purposes. The applicability of this document to a particular type of cable is as specified in the standard for the type of cable. Unless specified otherwise in a particular clause, IEC 60028 ED4 relates to the conductors in the finished cable and not to the conductor as made or supplied for inclusion into a cable. Conductors described in this document are specified in metric sizes. Informative annexes provide supplementary information covering temperature correction factors for resistance measurement (Annex B) and guidance on dimensional limits of circular conductors (Annex C). This document has the status of a horizontal publication in accordance with IEC Guide 108.

IEC 62056-6-1:2023(Main)
Electricity metering data exchange - The DLMS®/COSEM suite - Part 6-1: Object Identification System (OBIS)

IEC 62056-6-1:2023 is available as IEC 62056-6-1:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62056-6-1:2023 specifies the overall structure of the OBject Identification System (OBIS) and the mapping of all commonly used data items in metering equipment to their identification codes.OBIS provides a unique identifier for all data within the metering equipment, including not only measurement values, but also abstract values used for configuration or obtaining information about the behaviour of the metering equipment. The ID codes defined in this document are used for the identification of:
- logical names of the various instances of the ICs, or objects, as defined in IEC 62056‑6‑2:2023;
- data transmitted through communication lines;
- data displayed on the metering equipment, see Clause A.2 in Annex A.
This document applies to all types of metering equipment, such as fully integrated meters, modular meters, tariff attachments, data concentrators, etc.
To cover metering equipment measuring energy types other than electricity, combined metering equipment measuring more than one type of energy or metering equipment with several physical measurement channels, the concepts of medium and channels are introduced. This allows meter data originating from different sources to be identified. While this document fully defines the structure of the identification system for other media, the mapping of non-electrical energy related data items to ID codes is completed separately
This fourth edition cancels and replaces the third edition of IEC 62056-6-1, published in 2017. This edition constitutes a technical revision. The main technical changes with respect to the previous edition are listed in Annex B (informative).

IEC 60335-2-109:2023 is available as IEC 60335-2-109:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60335-2-109:2023 deals with the safety of UV radiation water treatment appliances for household and similar use, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances including direct current (DC) supplied appliances and battery-operated appliances. Appliances not intended for normal household use but that nevertheless can be a source of danger to the public, such as appliances intended to be used by laymen in shops and in light industry and farms, are within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account
- persons (including children) whose physical, sensory or mental capabilities; or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction;
- children playing with the appliance.
Attention is drawn to the fact that
- for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;
- in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities.
This standard does not apply to
- pumps (IEC 60335-2-41);
- luminaires for aquariums (IEC 60598-2-11);
- luminaires for swimming pools and similar applications (IEC 60598-2-18);
- appliances intended exclusively for professional use;
- appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).
This second edition cancels and replaces the first edition published in 2010, Amendment 1:2013 and Amendment 2:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) alignment with IEC 60335-1:2020;
b) modification or conversion of some notes to normative text (Clause 1, 6.2, 22.102);
c) introduction of IEC 60417 symbol for maximum operating depth (7.1, 7.6, 7.12.1);
d) addition of external accessible surface temperature limits (11.3, 11.8);
e) clarification of requirements for remote operation (22.40, 22.49, 22.51);
f) the requirements to emit harmful radiation are deleted, because they are covered in Part 1 (Clause 32).
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments unless that edition precludes it; in that case, the latest edition that does not preclude it is used. It was established on the basis of the sixth edition (2020) of that standard.
