Note on OPC Foundation membership

OPC Foundation Corporate Membership is strongly advised for anyone serious about OPC UA client or server development.

There are multiple reasons for this:

  • OPC Foundation offers a non-production sample OPC UA code - free to members - which you will want access to even if you decide to purchase a commercial SDK or toolkit in addition
  • Compliance and marketing: OPC UA products will be far more saleable if they have been validated by OPC Foundation's compliance and certification process

So, while membership may have been considered optional for developers using earlier OPC specifications, if is strongly recommended for UA development.

OPC Foundation

Non-production OPC UA Example Code

The OPC Foundation non-production examples are collections of libraries and applications that illustrate the development of UA applications. There are 3 different development environments: .NET (native and standard), C/C++, and JAVA with example support only for .Net environments.

Note: OPC Foundation supplies a full UA examples for .NET only. Support for C/C++ and Java is in the form of a stack and minimal examples. While a stack and examples provides the basic communications infrastructure, a full SDK adds significant application layer libraries and classes to speed up application development. UA developers are recommended to look to one of the third-party vendors listed on this page.
