It's used extensively for embedded devices, industrial control, IoT,\netc. - just about anything that has data that something else wants to monitor, control or visualize. \n\nRust is a systems programming language and is therefore a natural choice for implementing OPC UA. This implementation \nsupports the embedded, micro and nano profiles but may grow to support features in time.\n\nRead the [compatibility](./docs/compatibility.md) page for how the implementation conforms with the OPC UA spec.\n\nRead the [change log](./CHANGELOG.md) for changes per version as well as aspirational / upcoming work.\n\n# License\n\nThe code is licenced under [MPL-2.0](https://opensource.org/licenses/MPL-2.0). Like all open source code, you use this code at your own risk. \n\n# Setup\n\nRead the [setup](./docs/setup.md) for instructions on building OPCUA for Rust.\n\nRead [cross compilation](./docs/cross-compile.md) for hints for cross compiling OPC UA for Rust to other \nplatforms.\n\n# Migration notes\n\nIf you're using an earlier version of OPC UA for Rust, read the [migration](./docs/migration.md) notes.\n\n# Design\n\nRead the [design](./docs/design.md) for more in-depth description of implementation.\n\n# Tutorial\n\nTutorials / user guides are still work in progress. \n\n* [Client Tutorial](docs/client.md)\n* [Server Tutorial](docs/server.md)\n\n# Further Documentation\n\nThe API documentation is generated from the latest published crates. This may be some way behind current development. \n\n\u003ca href=\"https://docs.rs/opcua\"\u003e\u003cimg src=\"https://docs.rs/opcua/badge.svg\"\u003e\u003c/img\u003e\u003c/a\u003e\n\n# Samples\n\nIf you want to get stuck in, there are a number of samples in the samples/ folder. The `simple-client` and the `simple-server` projects are\nminimal client and server programs respectively.\n\n```bash\n# In one bash\ncd opcua/samples/simple-server\ncargo run\n# In another bash\ncd opcua/samples/simple-client\ncargo run\n```\n\nThe full list of samples:\n\n1. [`simple-server`](samples/simple-server) - an OPC UA server that adds 4 variables v1, v2, v3 and v4 and updates them from a timer via push and pull mechanisms.\n2. [`simple-client`](samples/simple-client) - an OPC UA client that connects to a server and subscribes to the values of v1, v2, v3 and v4.\n3. [`discovery-client`](samples/discovery-client) - an OPC UA client that connects to a discovery server and lists the servers registered on it.\n4. [`chess-server`](samples/chess-server) - an OPC UA server that connects to a chess engine as its back end and updates variables representing the state of the game.\n5. [`demo-server`](samples/demo-server) - an OPC UA server that is more complex than the simple server and can be used for compliance testing.\n6. [`mqtt-client`](samples/mqtt-client) - an OPC UA client that subscribes to some values and publishes them to an MQTT broker.\n7. [`event-client`](samples/event-client) - an OPC UA client that will connect to a server and subscribe to alarms / events.\n","funding_links":[],"categories":["Applications","应用","应用 Applications","应用程序 Applications"],"sub_categories":["Industrial automation","工业自动化","工业自动化 Industrial automation"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flocka99%2Fopcua","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flocka99%2Fopcua","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flocka99%2Fopcua/lists"}
