Architecture Before Implementation

OpenOpcUa is built on a simple principle:
An interoperable system requires architectural consistency, not shortcuts around the standard.
Strict compliance with IEC 62541 ensures that interoperability remains operational in real industrial deployments, not theoretical.

  • Full IEC 62541 alignment
  • No alteration or simplification of the standard
  • Clear separation between information modeling and application logic
  • NodeSet-driven dynamic modeling
  • Modular extensibility through VPI and VFI add-in mechanisms
  • Designed for industrial robustness and long-term maintainability

OOUAMiddleware Platform

OOUAMiddleware is the industrial deployment platform built on OpenOpcUa technology.
It delivers a complete and consistent OPC UA runtime environment engineered for demanding industrial systems.

  • Complete OPC UA Server and Client stack
  • High-performance C/C++ core implementation
  • Dynamic AddressSpace generation from NodeSet XML
  • Modular industrial data connectors
  • Historical Access and redundancy mechanisms
  • Architecture-consistent extensibility

OOUAMiddleware is currently available for industrial deployment without licensing fees.
Intellectual property remains under the control of its original author and is not transferred upon deployment.

Proven in Demanding Industrial Environments

OpenOpcUa-based deployments operate in demanding sectors where architectural consistency and long-term stability are critical.

  • Electric mobility systems
  • Mineral processing environments
  • Infrastructure and transportation systems
  • Advanced industrial automation platforms

Technical Direction

OpenOpcUa is developed under the technical leadership of Michel Condemine, official OPC Foundation expert in France and member of the Technical Advisory Council.
The platform reflects a rigorous, architecture-driven interpretation of IEC 62541, ensuring consistency, robustness and long-term industrial viability.
