Defi
L equipe devait connecter des equipements heterogenes sans remplacer les automatismes existants. Pump stations had mixed controllers, inconsistent telemetry and limited network resilience. Operators often had to call local technicians for basic status checks after alarms.
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 gateways collected pump, level and power data locally, buffered events during connectivity drops and exposed a clean data stream to SCADA.
Resultat
Le site a obtenu une exploitation plus stable, moins d interventions non planifiees et une collaboration plus rapide entre production, maintenance et IT. The utility moved from reactive phone-based troubleshooting to structured alarm review. The operations team also started comparing station energy profiles to detect inefficient pump behavior.
