Defi
L equipe devait connecter des equipements heterogenes sans remplacer les automatismes existants. Operators had local HMI visibility, but supervisors could not compare press behavior across lines. Changeover issues were discovered too late.
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 read approved PLC tags, exposed cycle and fault states, and sent a compact event stream to the plant dashboard.
Resultat
Le site a obtenu une exploitation plus stable, moins d interventions non planifiees et une collaboration plus rapide entre production, maintenance et IT. Supervisors identified repeat changeover gaps and caught transfer misalignment earlier. The team kept PLC logic untouched, which helped controls engineers approve the project.
