We have made our PI Developer Technologies more easily available. Anyone with an account on the Tech Support website or PI Square is now able to download the PI AF SDK, PI Web API, the PI OPC DA and PI OPC HDA Servers, and all products in the PI SQL Framework (PI OLEDB Provider, PI OLEDB Enterprise, PI JDBC Driver and PI ODBC Driver). We are doing this to make it easier for you to build applications that leverage PI System data. We are also allowing you to blog in public forums about using our PI Developer Technologies products, and to contribute to open-source projects that involve the PI System.
This does not mean that the PI Developer Technologies are license-free. You still need a PI System Access (PSA) license to deploy your applications. This is not a new requirement and we are not changing it. You might think of this as a run-time license. Note that the PI OPC DA and HDA Servers were also available under the older DA license. Talk to your Account Manager if you have questions about PSA or DA licenses.
