PI Coresight is an intuitive, web-based tool that delivers fast, easy, and secure access to all your PI System data. With PI Coresight you can easily perform ad hoc analysis, discover answers, and share your insights with others. © C o p y r i g h t 2 0 1 1 O S I s o f t , L L C 3 PI Coresight Architecture • Silverlight User Interface • Web Services in middle tier • PI System and SQL Server © C o p y r i g h t 2 0 1 1 O S I s o f t , L L C 4 PI Coresight Demo Watch for… • • • “Displays” “Symbols” The URLs in the browser © C o p y r i g h t 2 0 1 1 O S I s o f t , L L C 5 © C o p y r i g h t 2 0 1 1 O S I s o f t , L L C 6 Why Integrate? Allows a user to quickly open “interesting” data in PI Coresight without requiring a preexisting display or manual work. • Selected data items in PI Process Book, PI DataLink, PI WebParts, PI Notification (likely future features available from OSIsoft) • Custom applications © C o p y r i g h t 2 0 1 1 O S I s o f t , L L C 7 Building a sample application 1.

Endpoints – The paths of the URLs may change – AF Configuration may include additional URLs – Method calls intended for external consumption may be grouped together into a single “endpoint” Code – Expect code libraries (if provided) and XSDs will be updated.
