Decentralized Automation: The Future of Industrial Automation?

The future of industrial automation, according to Dr. Ulrich Viethen, CEO of Murrelektronik, isn’t about bigger, more centralized control systems. It’s about distributing intelligence and power closer to the machines themselves. This shift, termed “decentralized automation,” represents a fundamental rethinking of how factories are designed and operated, moving away from traditional control cabinets and towards a more flexible, efficient, and scalable model. The core idea behind this approach is to bring the automation technology directly to the point of application, reducing complexity and increasing responsiveness. This concept of decentral automation is gaining traction as manufacturers seek to optimize their processes and adapt to rapidly changing market demands.

Viethen’s vision, unveiled through a new concept for cabinet-free machine construction, isn’t simply a technological upgrade; it’s a philosophical one. He argues that traditional centralized systems, although historically dominant, are increasingly becoming bottlenecks in modern manufacturing environments. The complexity of wiring, the physical space required for control cabinets, and the limitations they impose on scalability are all factors driving the demand for a more distributed approach. This isn’t just about shrinking the footprint of automation equipment; it’s about fundamentally changing how machines are built and maintained, enabling greater agility and reducing downtime.

The Rise of Cabinet-Free Machine Construction

For decades, the industrial control cabinet has been a ubiquitous feature of manufacturing facilities. It houses the components that control and monitor machinery – power supplies, relays, programmable logic controllers (PLCs), and various other control elements. However, this centralized architecture presents several challenges. Wiring can become incredibly complex, making troubleshooting difficult and time-consuming. Changes to the system often require significant downtime and specialized expertise. And as factories strive for greater flexibility and customization, the rigid nature of traditional control cabinets can become a major impediment.

Murrelektronik’s approach, as detailed in their interview with Konstruktionspraxis, involves distributing these functions throughout the machine itself. Instead of a central control cabinet, individual modules are placed directly on or near the components they control. This eliminates the demand for extensive wiring, simplifies maintenance, and allows for greater modularity. Each module handles a specific task, communicating with other modules and a central control system via industrial Ethernet networks. This architecture allows for easier expansion and modification of the system, as new modules can be added or removed without disrupting the entire operation.

Benefits Beyond Space Savings

The advantages of decentralized automation extend far beyond simply freeing up floor space. Reduced wiring complexity translates directly into lower installation costs and faster commissioning times. The modular nature of the system makes it easier to adapt to changing production requirements, allowing manufacturers to quickly reconfigure their lines to accommodate new products or processes. The distributed architecture enhances system reliability. If one module fails, it doesn’t necessarily bring down the entire machine, minimizing downtime and maximizing productivity. This is particularly crucial in industries where even short interruptions can have significant financial consequences.

Viethen emphasizes the importance of co-creation with customers in developing these solutions. Murrelektronik doesn’t simply build products in isolation; they work closely with their clients to understand their specific needs and challenges, tailoring their solutions to meet those requirements. This collaborative approach ensures that the resulting systems are not only technologically advanced but as well practical and effective in real-world applications. The company’s focus on understanding the nuances of different industries – from automotive to food and beverage – allows them to deliver solutions that address the unique demands of each sector.

Addressing Cybersecurity Concerns

A natural concern with any distributed system is cybersecurity. With more devices connected to the network, the potential attack surface increases. However, Murrelektronik addresses this challenge through a multi-layered security approach. This includes secure communication protocols, robust authentication mechanisms, and regular security updates. The company also emphasizes the importance of network segmentation, isolating critical systems from less secure networks. They work with customers to implement best practices for cybersecurity, ensuring that their systems are protected against potential threats. The increasing focus on industrial cybersecurity is a key driver of innovation in this space, and companies like Murrelektronik are at the forefront of developing solutions to mitigate these risks.

The Future of Flexible Factories

Decentralized automation isn’t just a trend; it’s a fundamental shift in how factories are designed and operated. As manufacturers face increasing pressure to become more agile, efficient, and responsive to customer demands, the benefits of this approach will become even more apparent. The ability to quickly adapt to changing market conditions, reduce downtime, and lower costs will be critical for success in the years to come. The move towards Industrial Internet of Things (IIoT) and smart manufacturing further reinforces the need for distributed intelligence and seamless connectivity.

Murrelektronik plans to continue investing in research and development, expanding its portfolio of decentralized automation solutions and working closely with customers to address their evolving needs. The next step, according to industry analysts, will be the integration of artificial intelligence (AI) and machine learning (ML) into these systems, enabling even greater levels of automation and optimization. The company is actively exploring these technologies, seeking to leverage their potential to further enhance the performance and efficiency of its solutions.

The evolution of automation is ongoing, and the principles of decentralization championed by Murrelektronik are poised to play a significant role in shaping the factories of the future. What are your thoughts on the shift towards decentralized automation? Share your insights in the comments below.
