Annotation of standard text IEC 62682-ed.2.0 :
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. LIEC 62682:2022 specifie les principes et les processus generaux pour la gestion de systemes d’alarme bases sur des systemes de commande et des interfaces homme-machine (IHM) pour des moyens dans les industries de transformation. Il couvre toutes les alarmes presentees a l’operateur par le systeme de commande, qui incluent les systemes de commande de processus de base, les annonceurs, les systemes conditionnes et les systemes instrumentes de securite. Les pratiques dans le present document sont applicables aux processus continus, aux processus par lots et aux processus discrets. Il peut y avoir des differences de mise en ouvre pour satisfaire aux besoins specifiques en fonction du type de processus. La fonction premiere du systeme d’alarme est de notifier aux operateurs les conditions de processus anormales ou les dysfonctionnements du materiel et d’aider a leur resolution. Les systemes d’alarme peuvent inclure tant le systeme de commande de processus de base (BPCS) que le systeme instrumente de securite (SIS), qui utilisent chacun les mesures des conditions de processus et une logique pour produire des alarmes. La Figure 1 represente les concepts d’alarme et de flux de donnees de reponse dans le systeme d’alarme. Le systeme d’alarme inclut egalement un mecanisme pour communiquer les informations d’alarme a l’operateur par l’intermediaire d’une IHM, habituellement un ecran de calculateur ou un annonceur. Les fonctions supplementaires du systeme d’alarme consistent en un journal des alarmes et des evenements, un historique des alarmes et la production d’une metrique de performances pour le systeme d’alarme. Il existe des systemes externes qui peuvent utiliser les donnees issues du systeme d’alarme.
