Multiplatform stand-alone OPC UA server that lets you simulate your own data models.

Use Prosys OPC UA Simulation Server for testing OPC UA client applications and learning the technology. It supports all the essential OPC UA features. The Simulation Server is developed with Prosys OPC UA SDK for Java, so it is truly cross-platform and available for Windows, Linux and macOS.

NEW: Information Modeling

In OPC UA, information models play an important role, and they are also an important part of the Reference Architecture Model for Industry 4.0 (RAMI 4.0). At the moment, the OPC Foundation works with many different organizations to create OPC UA information models for different industrial domains.

The highly popular Free Edition already enables you to create your custom objects and leverage all simulation capabilities using the OPC UA Standard Information Model.

With the NEW Professional Edition you can import any OPC UA information models into the server and take advantage of the domain specific standardization work that is going on.

These features help you to develop and test information models without any real equipment. This makes the Simulation Server a valuable tool for integrators, but also for equipment and system vendors that work to support Industry 4.0, Plug & Produce and other smart manufacturing solutions.

Simulation of Data and Events

Prosys OPC UA Simulation Server includes predefined simulation signals that can be connected to any variable and let you simulate data of real equipment, especially with the help of Information Models. The signals provide also simulation of data history according to OPC UA specifications.

The server comes with predefined simulated events and event history, which helps you to test client applications accordingly.

Demonstration and Learning

Prosys OPC UA Simulation Server comes with an easy to use user interface that helps you to configure your data models, connection settings and simulation data fluently.

The user interface makes it also easy to demonstrate OPC UA capabilities to your colleagues and students - not to speak what you can learn yourself with it!

Connections and Security

Prosys OPC UA Simulation Server supports several connection types and all standard OPC UA Security Modes and Policies. This enables you to test connections with all client applications accordingly. You can also initiate Reverse Connections, which help to pass firewalls without opening specific ports.

You can also monitor currently active connections, manage application instance certificates and even track low level communication messages independent of the security settings.

Certified for Compliance

Prosys OPC UA Simulation Server is certified by the OPC Foundation to be OPC UA compliant. The OPC Foundation’s Certification and Compliance program exists to help members develop and provide high quality products that meet minimum operability requirements.
