Rapid OPC UA Server Development

OPC Wizard is a software toolkit for rapid development of OPC UA servers (OPC Unified Architecture). Its aim is to allow the fully functional server be developed with minimal boilerplate code and programming effort. Intricacies of OPC UA standard are handled by the OPC Wizard internally, and hidden from the developer.

The toolkit provides system integrators, OEMs and software developers with ability to create their own OPC UA servers without having to learn and implement the thousands of pages of OPC UA specifications.
