Empowering Plant Floor Operators with LLMs Using Unified Namespace and On-Prem AI

Feb. 24, 2025
It’s not about deploying new technology for technology’s sake, it’s about getting advanced tools into the hands of the people to create smarter operations and transform manufacturing from the ground up.

It wasn’t too long ago that I found myself stretched thin, juggling the relentless demands of work and the whirlwind of personal responsibilities. Deadlines at the office seemed unending, and the to-do list at home only grew longer. Enter AI, specifically ChatGPT. But in my world, it goes by a simpler, more personable name: Gary. Yes, that’s right. Gary. The 'G' in GPT was just too good to pass up and, somehow, this digital assistant became more than just a novelty; it became a game-changer for me.

Need a quick draft summarizing your thoughts for a scope of work? Gary’s got it. Want to learn a new skill over the weekend? Gary’s your guy. From finding creative solutions to simplifying complex tasks, Gary helped me carve out efficiencies that seemed impossible before. Whether it was organizing family events or streamlining project workflows, Gary proved to be the extra pair of hands and the extra brain I needed.

Yet, as remarkable as Gary is for personal productivity, the potential of AI stretches far beyond the daily grind. Imagine the transformative impact of AI on the manufacturing plant floor, where efficiency isn’t just nice to have, it’s critical. While a relatively new concept in the industrial world, integrating large language models (LLMs) with advanced software layers like unified namespace (UNS) can allow manufacturers to unlock the full potential of their data. 

Here’s how it works: UNS abstracts and unifies information from diverse sources, creating a comprehensive and organized view of operations. When paired with a secure, on-premises AI deployment, this approach can empower operational staff to work smarter with the help of a digital assistant.

Industrial extract, transform, load (ETL) and the power of the unified namespace (UNS)

For manufacturers, AI-readiness begins with data. But unlike the organized datasets you might find in traditional IT systems, manufacturing data is a different beast. It’s real-time, complex and originates from a variety of sources like PLCs, historians, LIMS, MES and ERP. This is where industrial ETL (Extract, Transform, Load) becomes essential.

Industrial ETL involves extracting data from these diverse sources, transforming it into usable formats and loading it into systems that can analyze and make use of it. The variability in data formats and sources, ranging from process variables and machine statuses from the PLC to operational data in other siloed enterprise systems, makes this process uniquely challenging. Yet, it is the cornerstone for creating a unified namespace.

Instead of spending hours sifting through endless logs or navigating complicated dashboards, the AI processes the question, retrieves relevant data via the UNS and delivers clear, actionable answers.

The UNS acts as the single source of truth, integrating and contextualizing data from across the manufacturing landscape. Functioning as a hub-and-spoke architecture, it breaks down silos by enabling real-time data flow between all connected systems, whether horizontally across systems at the same level or vertically across hierarchical levels. This unified approach organizes and contextualizes operational data into a standardized structure, creating a reliable foundation that advanced technologies — such as AI, advanced analytics platforms, digital twins, industrial IoT (IIoT) systems and predictive maintenance tools — can leverage to generate actionable insights.

Boosting operations with AI

Operational staff are the backbone of any manufacturing facility. They know the ins and outs of the day-to-day operation of the equipment and processes but often lack the tools to interpret vast amounts of data at their disposal. 

That’s essentially what can happen when LLMs are integrated with data contextualized in a UNS. This combination empowers subject matter experts (operators, technicians, supervisors, engineers and lab analysts) with intuitive tools to navigate complex data, enabling them to uncover actionable insights faster and make more informed decisions in real time.

Imagine an operations supervisor asking an industrial version of Gary:

  • Why did we have unexpected downtime during the night shift? 
  • What adjustments can improve yield in the next production run? 
  • How can we reduce energy consumption during peak hours? 

Instead of spending hours sifting through endless logs or navigating complicated dashboards, the AI processes the question, retrieves relevant data via the UNS and delivers clear, actionable answers. It’s like having Gary on the plant floor — always ready to assist and always equipped with the right information. 

Even with this advance, it’s still the expertise of the plant floor staff that steers Gary’s responses, ensuring the insights are meaningful and aligned with real-world operations.

Simplifying on-prem AI infrastructure

As exciting as cloud-based AI services are, they’re not always the best fit for manufacturing environments. Concerns about data security, latency and compliance are driving a shift toward on-premises AI as a more practical solution. Manufacturers require infrastructure capable of supporting the demanding workloads of advanced models like LLMs.

Cisco, a pioneer in AI infrastructure, has developed validated designs that integrate compute, storage and networking into modular configurations. These systems, known as AI Pods, offer a full-stack solution that allows manufacturers to deploy advanced AI technologies without the complexity of building custom systems from scratch. With their modular design, AI Pods enable organizations to start small, evaluate their needs and seamlessly scale as AI adoption grows.

By combining industrial ETL, unified namespace, and on-prem AI infrastructure, manufacturers can create a seamless, secure and efficient environment for AI adoption. It’s all about getting these advanced tools into the hands of the people who can take action and make a real impact. 

So, why not bring a little bit of Gary to your plant floor? You might be surprised at how much you and your people can accomplish.
