What it does
- Provides a high-level async Client, Server, Node and Subscription API, plus low-level access to all OPC UA structures.
- Client supports connecting, browsing and reading values, subscriptions, method calls, history read, and encrypted communication.
- Server supports creating an address space, data change and event handling, methods, history, and certificate handling.
- Includes command line tools such as uadiscover, uals, uaread, uawrite, uacall, uasubscribe and uaserver.
- Some server features such as WebSocket, alarms, XML protocol and views are not implemented yet.
