12. CITGO Corpus Christi Refinery 11 Technical Stuff Explained page 1 of 2 PI Here, PI There, PI Everywhere PI WEB Graphics Application Process Flow: The first step in displaying ProcessBook graphics on the web is to generate a skeleton image. Each display that is selected for web presentation is entered into an Access db. A Visual Basic application queries the database and loads each display through ProcessBook’s COM interface. Once a display is loaded, all of the value and bar controls are hidden from the viewable area and a “jpeg” image is generated through the save-as function. This process is completely automated and only needs to be run/executed when a display is modified/updated through ProcessBook. Steps for configuring ProcessBook displays for web publication: 1) Assign ProcessBook(s) enter Displays for publication { Access Application } 2) Run Static Static Server Program to extract “jpeg” image(s) and publish to web Server { Access Application } 3) Assign Processbook Button(s) to appropriate display - { Access Application } ProcessBook does not expose the button’s link through its COM interface so the button must be manually linked to the appropriate display. PB buttons must be uniquely named 4) Create hyperlink to display on a “TreeView” or any Web Page on the IntraNet Operation: When the user opens a display, the jpeg image is downloaded through an ActiveX control that resides on the client. The control then accesses an active-server page and retrieves the live values from PI. Management Systems, Inc.

14. CITGO Corpus Christi Refinery 13 Project History - information PI Here, PI There, PI Everywhere PI WEB Graphics Application The PI WEB Graphics Project was initiated in the Summer of 1998 to replace an existing Legacy VMS Process Graphics Application. CITGO Corpus Christi Refinery has one of the World’s finest plant Graphics distribution applications which supplies users with Live Process Data. When the decision was made to move to PI, we needed a mechanism / application to replace our legacy VMS displays. The door was opened when OSI announced the release of ProcessBook 2.0 which provided the functionality of building “pdi” files. Another key was Microsoft’s release of IIS4.0 with Active Server Page capability which would allow us to update PI values on the WEB Server. The PDI files allow us to capture the image and tag value locations necessary for LIVE WEB Publication. Now all’s we had to do was to develop an application to gather, manage, and publish hundreds of process displays. We developed our WEB Graphics Application with Syntex Management Systems (Systems Integration Specialists) and have fully implemented the application on all CITGO CCR workstations. The project was developed using Project management principles and techniques including a comprehensive detail design document. We completed the project on schedule and within budget with all objectives exceeding expectations. The PI WEB Graphics Application is a complimentary product to OSI’s PI ProcessBook. Our WEB Graphics Tool provides Users access to Refinery Graphics from anywhere, meaning any CITGO Refinery, Corporate office, CITGO road warrior and business traveler. Real-time data is now available on our Intranet for casual browsing, troubleshooting, or providing feedback to the Corpus Christi Refinery as necessary. Management Systems, Inc.
