Conquering Automation Complexity to

A Swedish microbrewery identified automation as the key to resolving production bottlenecks, but faced a challenge common to small-scale food and beverage producers: most industrial automation platforms are designed for large manufacturing environments and carry cost, complexity, and physical footprint that far exceed what a microbrewery operation requires. Deploying an oversized system would burden the business with unnecessary licensing, maintenance overhead, and integration complexity. Yet the brewery needed genuine process control — consistent batch execution, motor speed regulation, and clear operator visibility — to maintain product quality and throughput. Without the right-fit solution, the status quo meant continued manual intervention, inconsistent production, and limited ability to scale.

Rockwell Automation addressed the challenge by specifying a tightly integrated suite of Allen-Bradley components scaled to the brewery's exact needs. The Allen-Bradley Micro800 PLC serves as the control core, handling process logic for brewing sequences without the overhead of a full ControlLogix platform. Allen-Bradley PowerFlex 4M variable-speed drives provide precise motor control for pumps and conveyors, allowing the brewery to regulate flow rates and process speeds accurately. The Allen-Bradley PanelView 800 HMI gives operators a larger, higher-resolution interface for monitoring production status and diagnosing issues at a glance. These three components are engineered to work together natively within the Allen-Bradley ecosystem, reducing integration effort and ensuring reliable communication between control, drive, and visualization layers.

The deployed solution delivered on its core objective: a right-sized automation system that matched the brewery's scale without sacrificing capability.

• Lower total cost of ownership compared to larger-scale automation alternatives, with reduced licensing and maintenance burden
• Lower component cost through selection of Allen-Bradley's compact product tier rather than enterprise-grade hardware
• Improved operator experience via the PanelView 800's larger display, enabling faster identification of production status and issue resolution

The integration between PLC, drives, and HMI reduced system complexity, and the brewery gained a foundation it can build on as production volumes grow.

• Right-sizing automation matters: Deploying enterprise-scale control systems in small facilities inflates cost and complexity — match the platform to the operational scale.
• Integrated product families reduce risk: Selecting PLC, HMI, and drives from a single vendor ecosystem minimizes compatibility issues and simplifies commissioning.
• HMI quality directly affects operations: A clearer, larger operator interface reduces response time to production issues and supports faster operator training.
• Total cost of ownership should drive vendor selection: Upfront component cost is only part of the equation — maintenance, support, and upgrade paths determine long-term value.
• Small-scale producers can achieve industrial-grade control: Purpose-built compact automation platforms make sophisticated process control accessible without enterprise budgets.
