Defi
L equipe devait connecter des equipements heterogenes sans remplacer les automatismes existants. Pump skids were spread along a pipeline with limited connectivity. Operators had basic alarms but little context for pressure trends or motor load.
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 buffered pump, pressure and power data locally and synchronized when network quality improved. Remote access was restricted to maintenance roles.
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 site reduced inspection drives and detected a recurring suction issue before it caused a pump failure.
