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.

OpenOpcUa Technology | OPC UA Middleware
  • 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.

Industrial Deployment Through OOUA Integration Partners

OOUAMiddleware is deployed in industrial projects through qualified system integrators who manage implementation, commissioning and first-level customer support.
4CE Industry develops and maintains the OOUA technologies and provides partner training, remote Level 2 technical support and specialized engineering services.
The OOUA Integration Partner Program establishes a framework for industrial integrators working with OOUAMiddleware.

Industrial References & Deployments

OpenOpcUa technologies are used in industrial production, transportation infrastructure, fire detection and enterprise-wide information integration. The entries describe end-user applications and integrator contributions, including TYCO’s role in the ADP deployment.

EMOTORS — Manufacturing Operations

OOUAMiddleware connects Dassault PLM and Microsoft ERP with production lines and PLCs. It distributes manufacturing instructions and production orders to industrial equipment, collects and stores traceability data, and exchanges production information with the ERP to support manufacturing operations.

IMERYS — Mineral Processing

An OPC UA information model jointly designed by 4CE Industry and IMERYS structures production data for mineral processing operations. OOUAMiddleware instantiates this model, acquires data from industrial equipment through communication interfaces, and exposes the resulting information to OPC UA client applications.

CAP TUNNEL — Tunnel Boring

CAP TUNNEL develops solutions for tunnel boring machine guidance, monitoring and production data analysis. OpenOpcUa technology is used in an industrial control solution for tunnel boring machines, within this specialist field of underground tunnel construction.

RENNES MÉTROPOLE / KEOLIS — Metro Operations

A dedicated VPI developed in 2020 connects OOUAMiddleware to the SYSTRANS passenger information and control system. OOUAMiddleware centralizes exchanges and supplies information to Rennes metro supervision. The integration illustrates the use of dedicated VPIs to maintain interoperability between existing operational systems and metro supervision.

TYCO — Fire Detection & Safety Systems

At TYCO’s request, 4CE Industry developed a dedicated VPI enabling OOUAMiddleware to communicate with TYCO fire detection and fire safety systems. TYCO also integrates OOUAMiddleware within the ADP environment, using the common OPC UA information model shared with other integrators.

ADP — Airport Infrastructure

A common OPC UA information model provides a shared foundation for multiple integrators working across ADP airport infrastructure. TYCO and Chubb Sécurité have integrated OOUAMiddleware using this model, supporting interoperability between systems through a consistent representation of information.

Architecture Before Implementation

OpenOpcUa is built on a simple principle:
An interoperable system requires architectural consistency, not shortcuts around the standard.
OOUAMiddleware implements OPC UA services and information modeling mechanisms defined by IEC 62541, providing a standardized foundation for interoperability across industrial systems.

  • 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

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.

Sustain the OpenOpcUa Core

OpenOpcUa evolves through long-term technical stewardship.
Organizations relying on the middleware can contribute to sustaining its development and architectural continuity.
