Anonymous Flour Mill Operator (via RAM Elettronica)

A leading Italian flour mill manufacturer operating five geographically dispersed production sites faced a critical modernization challenge: its control infrastructure ran on Windows XP with a legacy PLC — a non-standardized, aging foundation that offered no centralized visibility across sites. In flour milling, where supply chain continuity is non-negotiable (a mill stoppage cascades directly to pasta factories and grocery shelves), the inability to monitor or manage all plants from a single point represented both an operational risk and a strategic liability. Without cross-site data aggregation, performance analysis and timely decision-making were effectively impossible.

System integrator RAM Elettronica — which supports 85% of medium-to-large Italian milling and pasta companies — deployed a unified control and supervision platform across all five sites using exclusively Rockwell Automation technology. The architecture is built on Allen-Bradley GuardLogix SIL 2/PL d safety controllers, with control and supervisory software developed entirely from PlantPAx DCS high-level libraries to enforce standardization. FactoryTalk View handles supervisory visualization; FactoryTalk Historian Site Edition captures process data. All five sites share a single server housed in a Rockwell Automation Industrial Data Center (IDC), enabling real-time plant-floor control and cross-site data exchange. The system spans over 3,000 I/Os and nearly 15,000 tags. A pilot was validated before full rollout, and ThinManager is being used to extend operator access to thin-client HMIs and mobile tablets.

The modernization delivered a single control room from which operators monitor and manage all five plants across Italy. Key outcomes include:

• Centralized visibility: All plant supervision, historian, and data aggregation now run on one unified Rockwell Automation software suite — no custom code required.
• Standardized technology: PlantPAx libraries enforced identical control, monitoring, and supervisory configurations across every site and process measurement point.
• Security compliance: The architecture meets IEC 62443-3-3 functional security requirements.
• Operational continuity: Seamless inter-site communication ensures that a disruption at one plant does not propagate across the supply chain.

Operators, including shift managers, can now access contextual asset performance and maintenance data via tablet while moving through facilities.

• Start from scratch rather than copy-pasting legacy approaches — the client's willingness to abandon the prior non-standardized system was the prerequisite for achieving true multi-site uniformity.
• Library-driven DCS deployment enforces standardization at scale — PlantPAx high-level libraries eliminated configuration drift across five independent sites.
• A shared Industrial Data Center is the keystone of multi-site control — centralizing the historian and data server removes the need for per-site analytics infrastructure.
• Business continuity must be designed in, not bolted on — redundant, safety-rated controllers (SIL 2/PL d) are table stakes in continuous-process food manufacturing.
• Domain expertise from the system integrator matters as much as the technology stack — RAM Elettronica's 20+ years in milling automation was cited as a decisive factor in project success.
