Fully connecting the plant to global clouds now collides with European regulators and CFOs who no longer tolerate dependence on foreign providers; 2026 is the year we rethink where industrial data actually lives.
Industrial edge computing moves processing capacity from the centralised cloud to the plant floor, the machine, or the robotic cell. Local latency (10-50 ms) is critical for process control, machine vision, and safety systems: it is a physical limit that bandwidth alone cannot solve. OPC UA, K3s, and private 5G now form a proven production-ready stack.
OPC UA is the standard protocol (IEC 62541) that connects industrial PLCs to IT systems, with built-in security and rich information models that Modbus or Profibus cannot match. Incremental adoption in phases, starting with an observer-mode gateway that leaves existing PLCs untouched, lets a plant running decades-old equipment modernise without stopping production.
