Server SDK

Build an OPC UA server with OpcUaServer, managed namespaces, and application-owned data. Start with Getting started and Your first server.

The guide is being written for 1.2.0-SNAPSHOT. Topic outlines link to current examples and feature guides. See the 1.2.0 migration guide when upgrading an existing server.

Foundation

1. Configuration: endpoints, identity validation, limits, and lifecycle.
2. Address space: namespaces, nodes, references, and stable identities.
3. Data access: Variables, attribute filters, reads, and writes.
4. Security: certificates, trust, and secured endpoints.
5. Access control: roles, user attributes, and authorization.

Live data and behavior
