The Factory Finally Gets a Kernel: Software-Defined Automation and the End of the PLC Monolith
The programmable logic controller earned its place through relentless determinism — but that determinism came at the cost of a fragmented, hardware-bound architecture. Software-defined automation, demonstrated by Siemens at Hannover Messe 2026, virtualizes control logic onto industrial PCs, collapses OT and IT workloads onto shared edge infrastructure, and opens the engineering toolchain through API-first design. For the Senior Architect, the implications touch procurement, security, organizational design, and the decade-long trajectory of manufacturing infrastructure decisions.
