The bottleneck of conventional UA SDKs is the encoder/decoder part of the OPC Foundation Stack.

This new SDK includes a new optimized stack that was developed from scratch and contains an encoder/decoder which is about ten times faster than the OPC Foundation variant.

Of course our stack is fully wire compatible with standard stacks.

Key features:

• simple and easy to use ANSI C API
• low memory footprint
• configurable memory pools
• address spaces can be stored in ROM to reduce RAM requirements
• works single-threaded and asynchronous
• possibility to run using multiple processes to benefit from multi-core or multi-cpu systems; real parallelism can speed up the server
• option to run critical components like the request decoder in a sandbox
• security support: supports encryption and signing using OpenSSL or mbedTLS backend
• user management and authorization support
• includes extensive unit test framework, which helps porting the SDK to new platforms
• optional file support for loading address spaces from file (binary or XML)
• API documentation with examples and tutorials
• much more
