    Quilmes SA - depalletizer PLC modernization

    Argentina โ€ข industrial depalletizers

    Situation:

    Machines running on very old wired and analog PLC systems as part of a wider plant modernization and monitoring effort.

    What was at risk:

    Upgrade two depalletizers without losing operational control while integrating local sensing, industrial communications, and plant-level monitoring.

    What we handled:

    Migrated the machines to a modern Siemens PLC with ProfiBUS, added subpanels for local sensor control and monitoring, retransmitted gateways to the master PLC, and connected the system to the plant network for dashboard integration.

    Operational outcome:

    Two machines modernized and ready for the new plant monitoring scheme, with better visibility, diagnostics, and a stronger technical base for future continuity.
    Tech footprint: Siemens PLC, ProfiBUS, subpanels, industrial gateways, local sensors, plant network, and monitoring.

    Start with a focused diagnosis

    We clarify what is failing, what is urgent, and what the right next step looks like.
