OPC UA SDK 1.1

OPC UA SDK by the OPC Foundation is a set of libraries, stacks, and tools for building secure, interoperable applications based on the OPC Unified Architecture standard. It enables developers to implement OPC UA servers, clients, and PubSub components across embedded devices, gateways, on-premises systems, and cloud environments.

Key capabilities:

• Comprehensive support for core OPC UA services: information modeling and address space, discovery, sessions, subscriptions and monitored items, data access, alarms and conditions, historical data and events, methods, and diagnostics.
• Built-in security aligned with the OPC UA specification, including encryption, signing, user authentication, and certificate management.
• Support for both Client/Server and PubSub communication models, using standard OPC UA transports and message mappings.
• Cross-platform stacks and reference implementations for popular languages such as C/C++, .NET, and Java.
• Samples, tooling, and conformance resources to accelerate development and interoperability testing.
• Scalable architecture suitable for constrained embedded targets through enterprise-class applications.

Maintained by the standards organization behind OPC UA, the SDK helps ensure reliable interoperability across vendors and ecosystems. Use it to build industrial automation and IIoT solutions that require robust data connectivity, eventing, historical access, and standardized information models.
