Modernizing Legacy Automation Systems for Peak Performance and Long-Term Reliability
At SB Automation Engineering SRL, we specialize in industrial automation system upgrades and retrofits, helping manufacturers and facility managers breathe new life into outdated control architectures. As technology evolves, keeping legacy systems running on obsolete hardware or unsupported software becomes risky and expensive. That’s where we step in—with solutions that preserve your existing investment while transforming it into a smart, efficient, and modern automation environment.
Whether you’re working with old PLC platforms, SCADA interfaces, electrical panels, or entire robotic cells, we help you transition to Industry 4.0 standards with minimal downtime and maximum return.
With hands-on experience across Siemens, Rockwell, Omron, Delta, Schneider, and other major brands, we understand both legacy platforms and modern systems inside out. Our retrofit process preserves your infrastructure’s integrity while unlocking the benefits of smart automation, cloud connectivity, energy savings, and predictive maintenance. We take care of everything—from hardware migration, software rewriting, field rewiring, and FAT/SAT—so you don’t have to worry about integration issues or unexpected breakdowns.
What’s Included in Our System Modernization Services
- PLC Platform Migrations – We replace outdated logic controllers (like Siemens S5, Allen-Bradley SLC, or Omron C-series) with current-generation TIA Portal, ControlLogix, or NX-series PLCs.
- SCADA & HMI Redevelopment – Upgrade legacy interfaces to modern, web-based SCADA dashboards and intuitive HMI layouts with enhanced visualization and mobile access.
- Control Panel Rewiring & Reconfiguration – Refitting existing electrical cabinets with updated circuit protection, wiring layouts, and compliant panel components.
- Drive & Motion Controller Replacement – Upgrade legacy VFDs, servos, and motion control systems to boost energy efficiency and process responsiveness.
- Software Version Consolidation – Eliminate fragmented control environments by unifying your automation software across platforms and systems.
- Electrical Retrofit Services – Replace outdated switchgear, sensors, relays, and I/O modules while maintaining field connectivity and wiring continuity.
- Field Device Compatibility Audits – Ensure all sensors, actuators, and auxiliary equipment support the new system infrastructure.
- Remote Access Enablement – Add secure, IIoT-ready remote monitoring and diagnostic capabilities to formerly standalone systems.
