Anonymous Large Cheese Manufacturer Achieves Greenfield Plant Startup On Time with Integrated Architecture

A large bulk cheese manufacturer and global whey ingredient supplier faced a high-stakes greenfield facility startup with a non-negotiable go-live date — the day local dairy farmers would begin delivering approximately 8 million pounds of milk daily. Missing that date meant halting an entire regional milk supply chain, not just a production delay. The project was undermined by compounding challenges: supply chain disruptions affecting equipment lead times, incomplete front-end documentation, late-breaking scope changes as engineering gaps surfaced, and insufficient internal resource bandwidth to absorb those changes without outside expertise.

Tri Tech Automation, a platinum-tier Rockwell Automation PartnerNetwork integrator, took ownership of automation, controls budgeting, and standards across the greenfield plant. The core decision was to implement an integrated architecture unifying process and power control — eliminating isolated automation islands by connecting 45 configured-to-order (CTO) CENTERLINE 2100 low-voltage MCCs, PowerFlex 523 and 525 AC drives, ControlLogix PLCs, FLEX 5000 I/O modules, and Stratix 5400 industrial Ethernet switches on a single physical OT network. To protect the schedule, Tri Tech ordered the MCCs before engineering was finalized, absorbing scope changes post-order. Customization, network integration, device parameterization, and factory acceptance testing (FAT) were all completed at Tri Tech's St. Louis facility before shipment. Endress+Hauser instrumentation was consolidated to reduce spares complexity and improve long-term supportability.

The facility met its predetermined startup date despite supply chain disruptions and late scope changes — avoiding a cascade failure across the regional dairy supply network. Key operational outcomes include:

• 643 connected loads (VFDs, starters, feeder breakers) totaling 19,500 HP / 27,500 A unified on a single physical network
• All MCCs, VFDs, I/O, and process gateways segmented via VLANs and IP schemes — no isolated automation islands
• Operators and maintenance personnel gained real-time, data-driven visibility across process and power systems
• Consolidated instrumentation reduced spares inventory complexity and improved vendor support coverage
• Improved sustainability outcomes through automated control of water and energy consumption

• Order configured-to-order equipment before engineering is complete — for greenfield food plants with fixed startup dates, early MCC procurement with a spare allowance buffer is lower risk than waiting for finalized drawings.
• Integrated architecture prevents automation islands — unifying process, power, safety, and energy management on one network reduces integration failures and gives operators a single source of truth.
• Factory acceptance testing at the integrator's facility catches configuration issues before equipment reaches the plant floor, compressing on-site commissioning time.
• OT network design is a first-class deliverable — documenting switch configurations, backup procedures, and replacement manuals at project close is essential for long-term operational resilience.
• Engage a system integrator early to identify engineering gaps before they become schedule threats.
