The Seitec OPC-Hub
We ensure the connectivity of your systems
The central access point for your data
OPC UA server for maximum transparency
The Seitec OPC-Hub is the central access point for your entire OPC UA server landscape. As an aggregating and historizing OPC UA server based on the certified Prosys SDK, it connects any OPC UA servers or umati gateways, dynamically merges their address spaces, and provides variables and events in real time via the standardized OPC UA client/server protocol.
Thanks to integrated historical access, users can also access complete variable and event his-tories without separate data recording. This creates a uniform database that makes existing OPC UA dashboards or software solutions directly usable and at the same time opens up new potential for analyses, process optimization, and AI-supported applications.
- Aggregation of different data sources
- Connectivity via OPC UA and MQTT
- Complete historical access
- Support for alarms and conditions (events)
- Modules: Server / Client / Viewer / Exporter
With the Seitec OPC-Hub, you can lay the foundation for networked, transparent and future-proof production.
The heart of data aggregation
The Seitec OPC-Hub / Server
The Seitec OPC-Hub / Server is the heart of the platform and serves as the central access point to your entire OPC UA server landscape. As an aggregating OPC UA server with integrated histor-ical access, it combines all data sources in a consistent environment.
An intuitive user interface allows for convenient configuration and monitoring, while a flexible information model enables the uniform mapping of complex machine structures. In addition, a powerful data logger is integrated, which records any number of variables per connection and makes them permanently available.
The OPC- Hub / Server thus creates the basis for transparent, secure and standardized data usage — from real-time information to a complete history.

Future-proof architecture
One system for OPC UA, MQTT
and persistent data storage
The architecture of the Seitec OPC-Hub / Server combines flexibility, standard compliance and future-proofing. Internal subscriber modules enable communication with any data sources such as OPC UA servers or umati gateways.
An aggregation layer consolidates the information, enriches it, and makes it available transparently to all connected applications via the central OPC UA server. Persistent storage ensures that not only live data but also historical values can be retrieved at any time via the standardized OPC UA interface. This creates a consistent system that supports both classic OPC UA client/server structures and modern MQTT-based communication.
For users, this means full control over the data landscape, easy integration of existing dashboards and the perfect foundation for analysis, optimization, and AI-based applications.

Data becomes information
The Seitec OPC Hub modules
– Client, Viewer, and Exporter
In addition to the server, the Seitec OPC-Hub includes other powerful components. The OPC-Hub / Client is a full-fledged OPC UA client that can be connected directly to the server and enables complex event handling – ideal for demanding applications and automated workflows.
The OPC-Hub / Viewer offers a powerful tool for detailed analysis: as an “offline OPC UA viewer,” it displays recorded data sets in a structured manner, visualizes relationships graphically and in tabular form, and supports targeted, user-oriented evaluation. The OPC-Hub / Exporter complements the solution by reliably transferring data to external systems and common standard formats, enabling seamless integration.
Together, these modules form a flexible modular system that companies can use not only to collect their data, but also to process, visualize and share it.

umati meets Seitec OPC Hub – the perfect complement
OPC UA and MQTT combined for seamless integration and machine connectivity
The umati ecosystem has established itself as an open standard for machine communication. The Seitec OPC-Hub extends this approach by providing MQTT-based PubSub data in parallel as a fully-fledged OPC UA server.
This means that existing dashboards and applications that use internal OPC UA clients can continue to be used without modification, including access to live data and historical values. The hub supports the latest OPC UA and umati standards and ensures maximum compatibility.
This creates a comprehensive solution that combines classic client-server models with modern PubSub communication – a secure foundation for digital transformation.
Future-proof and flexible
Added value for umati users
With the Seitec OPC-Hub, umati users benefit twice over: existing OPC UA dashboards can continue to be used seamlessly, while access to historical values opens up completely new analysis possibilities. For machine builders, this means faster and more efficient support, even without direct access to the machine.
The OPC UA Lab at Fraunhofer IWU confirms the software's standard conformity and interoperability, thereby underlining its practical suitability.
“umati gives machines a common language. The solution brings them into production across location boundaries and unlocks the full potential of production data.”
