ANSI C Based OPC UA Client SDK

The UA SDK is an ANSI C library designed for developing compact OPC UA Clients e.g. embedded or headless devices like PLC or railmount controllers and IPC. The ANSI C SDK is designed for single threaded use. The Client SDK is also available bundled with the Server SDK. Both use the same UA Base Library on top of the ANSI C OPC UA Stack.
