Management of alarm systems for the process industries

Management of alarm systems for the process industries

IEC 62682:2022 specifies general principles and processes for the management of alarm systems based on controls system and human-machine interfaces (HMI) for facilities in the process industries. It covers all alarms to be presented to the operator through the control system, which includes alarms from basic process control systems, annunciators, packaged systems, and safety instrumented systems.
The practices in this document are applicable to continuous, batch, and discrete processes. There can be differences in implementation to meet the specific needs based on process type.
The primary function within the alarm system is to notify operators of abnormal process conditions or equipment malfunctions and support the response. The alarm systems can include both the basic process control system (BPCS) and the safety instrumented system (SIS), each of which uses measurements of process conditions and logic to generate alarms. Figure 1 illustrates the concepts of alarm and response dataflow through the alarm system. The alarm system also includes a mechanism for communicating the alarm information to the operator via an HMI, usually a computer screen or an annunciator. Additional functions of the alarm system are an alarm and event log, an alarm historian, and the generation of performance metrics for the alarm system. There are external systems that can use the data from the alarm system.

Gestion de systèmes d'alarme dans les industries de transformation

L'IEC 62682:2022 spécifie les principes et les processus généraux pour la gestion de systèmes d’alarme basés sur des systèmes de commande et des interfaces homme-machine (IHM) pour des moyens dans les industries de transformation. Il couvre toutes les alarmes présentées à l’opérateur par le système de commande, qui incluent les systèmes de commande de processus de base, les annonceurs, les systèmes conditionnés et les systèmes instrumentés de sécurité.
Les pratiques dans le présent document sont applicables aux processus continus, aux processus par lots et aux processus discrets. Il peut y avoir des différences de mise en œuvre pour satisfaire aux besoins spécifiques en fonction du type de processus.
La fonction première du système d’alarme est de notifier aux opérateurs les conditions de processus anormales ou les dysfonctionnements du matériel et d’aider à leur résolution. Les systèmes d’alarme peuvent inclure tant le système de commande de processus de base (BPCS) que le système instrumenté de sécurité (SIS), qui utilisent chacun les mesures des conditions de processus et une logique pour produire des alarmes. La Figure 1 représente les concepts d’alarme et de flux de données de réponse dans le système d’alarme. Le système d’alarme inclut également un mécanisme pour communiquer les informations d’alarme à l’opérateur par l’intermédiaire d’une IHM, habituellement un écran de calculateur ou un annonceur. Les fonctions supplémentaires du système d’alarme consistent en un journal des alarmes et des événements, un historique des alarmes et la production d’une métrique de performances pour le système d’alarme. Il existe des systèmes externes qui peuvent utiliser les données issues du système d’alarme.

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).

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 60335-2-122:2023(Main)
Household and similar electrical appliances - Safety - Part 122: Particular requirements for commercial washing machines

IEC 60335-2-122:2023 deals with the safety of electrically operated commercial washing machines, their rated voltage being not more than 250 V for single phase and 480 V for other appliances.
These appliances are not intended for household and similar purpose. They are used:
- by experts or instructed persons for commercial washing in areas not open to the public, for example on farms and in hotels, hospitals, restaurants and canteens; or
- by laymen in areas open to the public, for example launderettes and communal laundry rooms.
The electrical part of appliances making use of other forms of energy is also within the scope of this standard.
These appliances are designed to be connected to hot or cold water supply.
Appliances making use of steam or hot water for heating purposes are also within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by these types of appliances. However, in general, it does not consider young 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, the national water supply authorities and similar authorities;
- in many countries, additional requirements are specified for appliances incorporating pressurized parts;
- for appliances having additional functions (e.g. drying function), other standards are also applicable.
This standard does not apply to:
- appliances designed exclusively for industrial purposes (ISO 10472-2);
- 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);
- washing machines appliances for household and similar use (IEC 60335-2-7).
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.
