Discussing the evolving landscape of AI in industrial automation reveals interesting perspectives on its current and potential applications. Real-time systems in industrial settings, for instance, differ significantly from their IT counterparts. While a website with a 30-second update interval might be considered real-time in IT, industrial controllers operate in the realm of microseconds, highlighting the vastly different scales and criticality of real-time operations.

AI's maturity in industrial automation lags behind other business applications due to the high stakes involved. In non-critical applications like marketing, AI errors are trivial, but in industrial contexts, mistakes can lead to significant damage or safety hazards. Therefore, AI solutions in manufacturing must be highly reliable and rigorously tested. However, the potential for AI in this field is vast, especially with companies like Nvidia and Siemens pushing the envelope with their collaborations.

One of the most promising applications of AI in manufacturing is in vision systems. AI-powered vision models can handle large volumes of data more effectively than traditional camera vision systems, making them invaluable for quality control and monitoring tasks. Many industrial automation vendors now offer AI-enhanced vision solutions, reflecting the maturity and reliability of these systems.

However, integrating AI directly into PLCs or control decisions presents challenges. AI requires extensive data to make accurate decisions and faces regulatory hurdles in industries like pharmaceuticals and food, where control algorithms must be validated. AI and machine learning models, by nature, evolve over time, making it difficult to ensure consistent regulatory compliance.

Despite these challenges, there are simpler, more immediate AI applications that could revolutionize the industry. For example, using AI to generate initial ladder logic routines from schematic descriptions or to translate existing programs into understandable documentation for non-engineers would significantly lower the learning curve for new control systems engineers. Additionally, AI could aid in troubleshooting by pinpointing the origins of errors within complex control systems, akin to stepping through code in traditional software development.

Companies like Beckhoff are already exploring these possibilities, offering tools that integrate AI to facilitate programming and troubleshooting in their systems. As the industry continues to innovate, these practical AI applications could bridge the gap between traditional control systems and the future of intelligent automation, making advanced manufacturing technologies more accessible and efficient.
