OSIsoft is introducing PI Web Services as another standards-based data access tool available to users. This product will provide platform-independent and language-independent access to the PI System. We will demonstrate how to develop .NET, Java, and Silverlight applications using PI Web Services. We will also demonstrate how to integrate PI Web Services into Microsoft BizTalk and InfoPath, with no coding required. Finally, we will discuss the roadmap for upcoming releases of PI Web Services, including functionality to access both PI and AF data.
