Industrial OPC UA Platform

A Semantic-Model-Driven Middleware Architecture.

OPC UA middleware platform – NodeSet-driven domain modeling and industrial runtime

What is OOUAMiddleware?

OOUAMiddleware is a semantic-model-driven industrial OPC UA middleware platform built on strict IEC 62541 compliance. It unifies heterogeneous industrial data sources, adapts to structured OPC UA information models and delivers modular runtime capabilities for demanding environments.

Designed for Complex Industrial Environments

  • Multi-protocol integration
  • IT/OT convergence
  • Long lifecycle industrial systems
  • High availability requirements

Core Capabilities of the Platform

  • OPC UA Server & Client Stack
  • Modular Connectivity Drivers
  • Dynamic AddressSpace from NodeSet XML
  • Redundancy mechanisms
  • Structured Information Modeling
  • Companion Specification integration
  • Flexible Archiving (SQL, Parquet, Binary)
  • Extensible Plug-in Architecture

Platform Architecture Overview

OOUAMiddleware is built around structured OPC UA information models that define the semantic structure of the system. These models are created using official Companion Specifications or a dedicated industrial modeling methodology.
The semantic layer drives the runtime core, industrial connectors and archiving modules.

OpenOpcUa Industrial Data Model (OPC UA Modeling) → Based on standardized rules + OOUACoreServer + Data Collection Modules → Modbus, S7, EtherNet/IP, etc. + Archiving Modules → SQL, CSV, Binary = OOUAMiddleware

Industrial Protocol Integration

OOUAMiddleware is designed to integrate heterogeneous industrial data sources through a modular driver architecture. Data acquisition is handled by dedicated collection modules, allowing protocols to be added, updated or replaced without impacting the OPC UA core runtime or the information modeling layer.
The platform can act as an industrial data concentrator, mapping field-level data into structured OPC UA information models and exposing it through a consistent semantic interface.
Typical industrial integration scenarios include:

  • PLC and field device acquisition through modular protocol drivers
  • OPC UA aggregation and gateway architectures
  • OPC Classic wrapping for legacy environments
  • Incremental modernization where protocols coexist during migration phases

Supported and commonly used protocol modules include Modbus, Siemens S7 and EtherNet/IP, as well as OPC UA and legacy OPC Classic integration. Additional drivers can be implemented following the same modular principles, preserving long-term maintainability and strict IEC 62541 alignment.

Flexible Industrial Data Storage

OOUAMiddleware provides flexible and modular data storage mechanisms adapted to diverse industrial architectures.
Historic and operational data can be persisted using different storage backends depending on performance, traceability and analytics requirements. Supported storage options include relational SQL databases, structured file exports (CSV), native binary formats and high-efficiency columnar formats such as Apache Parquet for large-scale analytics environments.
The storage layer is fully decoupled from the runtime core. This separation allows organizations to evolve their data strategies — including integration with data lakes or cloud-based systems — without modifying the semantic information model or the OPC UA server layer.
OOUAMiddleware also supports OPC UA Historical Access, ensuring standardized access to archived industrial data in compliance with IEC 62541.

Deployment & Usage Model

OOUAMiddleware is available for industrial deployment without runtime licensing fees. Deployment does not imply transfer of intellectual property. The technology remains under the control of its original author.
Structured technical sponsorship and industrial support programs are operationally managed through 4CE Industry.
