In this episode of Automate 2025, we welcome Bernd Raithel from Siemens back to the show to discuss the evolution of industrial control systems and the future of manufacturing. As the Head of R&D for Siemens Factory Automation in the US, Bernd shares his unique perspective on bridging legacy PLCs with modern IT infrastructure, enabling software-defined automation, and empowering manufacturers with flexible and scalable digital tools. With deep insights into products like the S7-1200, S7-1500, TIA Portal, Sematic X, and Siemens Industrial Edge, Bernd explores how Siemens is supporting everything from small-scale modernization to large-scale transformation.
We cover critical trends shaping the next generation of manufacturing, including the rise of virtual PLCs (vPLCs), integration of AI into control systems, the shift from hardware to software-defined automation, and the challenges of IT and OT convergence. Bernd also highlights the importance of version control, DevOps pipelines, and open edge development in making industrial systems more agile.
We wrap up by looking at Siemens' global R&D structure, freemium software models for engineers, and how manufacturers can take their first steps into digital transformation—without boiling the ocean.
This is a must-watch conversation for engineers, IT leaders, and decision-makers in the automation space looking to understand what the future of control and connectivity looks like.
