OPC UA Simulation Server
Develop, Test, and Demonstrate OPC UA Solutions with Confidence.
Multi-platform stand-alone OPC UA server that lets you simulate your own information models
Use Prosys OPC UA Simulation Server for testing OPC UA client applications, learning the technology and building demonstrations. It supports all the essential OPC UA features including Data Access, Historical Access, Events and PubSub. Available for Windows, Linux and macOS, with option for headless operation ideal for automated tests.
Test OPC UA Clients
Connect clients and test them against a working server. Simulation Server supports all the standard security modes and policies, user authentication and reverse connections. Watch sessions, connection history and the raw messages.
Test OPC UA PubSub
Create publishers with connection addresses with protocol and encoding settings, writer groups, variable datasets and event data sets. Ensure your subscriber application is working properly and compliance with specifications.
Replicate Real Servers
Import Information Models, Server Address Spaces and Playback real data on imported nodes to simulate production behavior for validation, debugging or demonstration purposes. Attach simulation signals to any variable to imitate real equipment, with data and event history.
Automate Your Testing
Run Simulation Server headless in a container, in your automated tests and CI/CD pipelines. Capture a production server into a project once, then run that project unattended as often as you need.
