I have been working in the industrial automation business for more than 35 years, and over that time, seen technology progress massively. In my view, open software-defined automation (OSDA) is the most significant, game-changing development I’ve ever encountered.
It has been fascinating to contribute to the transformation of control systems, from hardwired logic to data-driven digital environments. However, one element that has remained constant during that time is the traditional programmable logic controller (PLC), which holds a central position in every control system.

It brought flexibility, reliability and standardisation, and for decades it evolved to meet modern demands. However, today, its dominance is being challenged by the realities of modern manufacturing.
Three major challenges in industry are driving a new change...
