Schwan's Modernizes Pet Food Manufacturing with Advanced Automation
Schwan's, a company with a rich heritage in frozen foods, embarked on a significant technological overhaul at its manufacturing facility in Oklahoma. Confronted with a landscape of aging control systems and obsolete hardware, the company sought to breathe new life into its operational infrastructure. The collaboration with NorthWind marked a pivotal moment, ushering in an era of advanced automation, characterized by the adoption of cutting-edge equipment and software. This strategic pivot not only addressed the immediate challenges posed by outdated technology but also laid a robust foundation for enhanced operational efficiency, streamlined processes, and future scalability, mirroring best practices in the pet food production sector.
This transformative project centered on a phased engineering approach, meticulously implemented by NorthWind, which encompassed a thorough assessment of existing systems, followed by a strategic migration to modern control hardware and software. The transition to an Ethernet/IP communication network and the integration of Ignition graphics dramatically simplified human-machine interfaces, consolidated diverse applications, and introduced sophisticated diagnostic and reporting capabilities. The outcome is a significantly more stable and manageable production environment, minimizing disruptions and paving the way for consistent performance and continuous improvement. This successful modernization initiative serves as a blueprint for other facilities grappling with the complexities of legacy systems, underscoring the profound benefits of proactive technological investment.
Comprehensive Automation Upgrade for Enhanced Operations
Schwan's, a legacy food company, encountered substantial operational hurdles due to outdated control systems and hardware at its Oklahoma plant. This included ancient programmable logic controllers (PLCs), obsolete RSV32 graphics, and a Windows NT-based system lacking security updates, posing considerable risks. To overcome these challenges, Schwan's engaged NorthWind for a comprehensive automation upgrade, aiming to implement modern solutions akin to those used in advanced pet food production facilities. This strategic investment sought to rectify decades-old technological inefficiencies and elevate the plant's operational capabilities.
The modernization initiative commenced with an exhaustive engineering study in 2023, meticulously cataloging and evaluating all control panels to determine the extent of intervention required—from minimal adjustments to complete replacements. Obsolete machinery was systematically replaced, and the entire communication framework was migrated to a state-of-the-art Ethernet/IP network. The archaic RSView 32 graphics were supplanted by advanced Ignition (Inductive Automation) graphics, centralizing supervisory control and introducing standardized tag-based naming across thousands of data points. This systematic overhaul not only addressed critical security vulnerabilities associated with the outdated Windows NT system but also transformed a fragmented, undocumented control environment into a cohesive, easily manageable, and highly efficient operation, providing a stable foundation for ongoing support and continuous improvement.
Streamlined Interfaces and Future-Ready Solutions
Before the comprehensive upgrade, Schwan's facility was plagued by an overly complex Human-Machine Interface (HMI) landscape, comprising 18 disparate applications, 36 HMIs, and over 300 screens—many of which were redundant or superfluous. This complexity led to increased training times for operators and hindered efficient troubleshooting. The modernization effort, spearheaded by NorthWind, dramatically simplified this environment, consolidating all functionalities into a single Ignition application. This streamlined setup now features a mere six HMIs and fewer than 25 screens, significantly reducing operational overhead and accelerating the learning curve for new personnel.
Beyond simplifying the interface, the modernization introduced robust enhancements in diagnostics, alarms, and reporting. Operators now benefit from standardized and customizable dashboards, offering a unified view of the plant's operations while allowing for tailored visibility into specific areas of responsibility. Advanced alarm analytics and reporting capabilities enable the identification of trends, such as recurring equipment faults, and provide summaries of production metrics, line efficiency, and top alarms at the end of each shift. These sophisticated tools not only facilitate proactive maintenance and minimize downtime but also establish a repeatable, scalable template for future facility upgrades and expansions, positioning Schwan's with a stable and supportable automation platform capable of meeting future demands.
