Defi
L equipe devait connecter des equipements heterogenes sans remplacer les automatismes existants. Substations used different generations of protection relays and meters. Field teams were losing time moving between sites for routine checks that rarely required physical intervention.
Approche Modibus
Modibus a ete deployee comme couche edge securisee: collecte locale, normalisation des donnees et acces controle pour les equipes operations et service. Modibus devices were deployed as a controlled access layer. Relay data was translated into a common structure and published to operations systems while VPN access remained outbound-only.
Resultat
Le site a obtenu une exploitation plus stable, moins d interventions non planifiees et une collaboration plus rapide entre production, maintenance et IT. Operators gained a consistent view of breaker status, meter values and communication health. Site visits shifted from routine inspection to planned maintenance.
