Overview

What does the OPC UA Universal Server do?

The OPC UA Universal Server connects to multiple industrial and IT systems, aggregates data from disparate sources, and converts it into a unified OPC UA information model — enabling secure, scalable communication across enterprise IT and OT systems. It can even aggregate other existing OPC UA servers into one address space, and is configured through the SIOTH® graphical builder, no custom code required.

Challenges Addressed by OPC UA Universal Server

Industrial environments struggle with siloed systems, varied protocols and slow, insecure data transfer. Legacy methods complicate digital transformation and obscure real-time insights.

Siloed Data Systems
Inconsistent Data Standards
Slow or Unreliable IT/OT Communication
Security and Compliance Risks

Why Choose OPC UA Universal Server?

Multi-Source Data Collection

Collects data from single or multiple disparate data sources with ease

Universal Protocol Conversion

Converts any industrial or IoT protocol to standard OPC UA

Fast, No-Code Configuration

Built in minutes using SIOTH® configurator — no heavy coding required

Secure & Scalable by Design

Ensures secure, scalable, and optimized for IT-OT-IIoT integration

Connectivity

Connect every protocol through one OPC UA interface

Instead of standing up a separate driver or gateway per system, the OPC UA Universal Server normalizes everything into a single OPC UA address space.

Security

OPC UA security, built in

Security is handled at the protocol level, not bolted on - matching how OT teams already segment plant networks.

Encryption and authentication

All OPC UA sessions use built-in encryption, signing, and certificate-based authentication.

DMZ and Purdue model support

Deploy on the DMZ layer to isolate OT networks when aggregating OT-layer OPC UA servers.

Frequently Asked Questions
A centralized OPC UA server that aggregates data from multiple industrial and IT systems and exposes it through a standardized OPC UA interface for secure and reliable data access.

Connects seamlessly to a myriad of protocols, including:

  • Industrial Protocols: Modbus, OPC DA (64/32), OPC HDA, OPC AE, OPC UA, DNP, S7, Allen Bradley, IEC -104, BACnet, J1939, SNMP

Yes. It can collect data from multiple OPC UA servers and expose them using a unified data model, and can be deployed on the DMZ layer to isolate OT-layer sources.

Yes, including alarms and status notifications, with a graphical interface for configuring input tags, history tags, and high/low alarms.

Built-in OPC UA security mechanisms — secure communication, authentication, and user access control.

Yes. Connect to Modbus devices and their data is exposed through a standard OPC UA interface without a separate Modbus driver on the consuming side.

Yes, designed to integrate with existing industrial infrastructures and legacy systems without replacing existing equipment.
