OPC UA
OPC UA matters because it provides runtime-facing industrial semantics and a bridge between design-time engineering structures and operational systems.
How EngineeringOS Uses It
EngineeringOS should use OPC UA as a semantic bridge for runtime integration, digital operations, and future closed-loop flows between engineered systems and live industrial environments.
Boundary
OPC UA should inform runtime integration and mapping, not replace the design-time semantic core. EngineeringOS remains the authoring and compilation authority upstream.
