EN IEC 62682:2023

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.

Alarmmanagement in der Prozessindustrie

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.

Upravljanje alarmnih sistemov za procesno industrijo (IEC 62682:2022)

Standard IEC 62682:2022 določa splošna načela in postopke za upravljanje alarmnih sistemov, ki temeljijo na nadzornem sistemu in vmesnikih človek-stroj (HMI) za objekte v predelovalni industriji. Zajema vse alarme, ki jih je treba operaterju predstaviti prek nadzornega sistema, kar vključuje alarme iz osnovnih sistemov za nadzor procesov, prikazovalnikov, sistemov pakiranja in sistemov z varnostnimi instrumenti.
Prakse iz tega dokumenta se uporabljajo za neprekinjene, serijske in diskretne procese. Izvajanje se lahko razlikuje glede na posebne potrebe, ki temeljijo na vrsti procesa.
Osnovna funkcija znotraj alarmnega sistema je obveščanje operaterjev o nenormalnih procesnih pogojih ali okvarah opreme in podpora pri odzivanju. Alarmni sistemi lahko vključujejo osnovni nadzorni sistem za proces (BPCS) in sistem z varnostnimi instrumenti (SIS), od katerih vsak uporablja meritve procesnih pogojev in logiko za ustvarjanje alarmov. Slika 1 prikazuje koncepte pretoka podatkov o alarmu in odzivu prek alarmnega sistema. Alarmni sistem vključuje tudi mehanizem za sporočanje informacij o alarmu operaterju prek vmesnika HMI, ki je običajno računalniški zaslon ali prikazovalnik. Dodatne funkcije alarmnega sistema so dnevnik alarmov in dogodkov, zgodovina alarmov in ustvarjanje kazalnikov učinkovitosti alarmnega sistema. Obstajajo zunanji sistemi, ki lahko uporabljajo podatke iz alarmnega sistema.
