10. 10 © 2008 OSIsoft, Inc. | Company Confidential So…use PI more, or better Monitoring –PI Health Monitor –Topview from Exele Information Systems –PIANO from OSIsoft (future) PI-TEEP –Batch processes – are batches running too long, or down for too long? –Continuous processes – are they running? If so, are they running hard enough? –Latest version uses xMii (SAP Portal) as a front end – universally available

12. 12 © 2008 OSIsoft, Inc. | Company Confidential Stretching the Limits of the PI System Rlink – PP/PI –Automated production recording –Calculations run every four hours, posting results to SAP within 20 minutes. –Before Rlink was implemented, operators spent 2-4 hours per week manually entering productions and consumption, with an average error rate of 5.8%. –After Rlink, manufacturing engineers spend approximately 2 hours per month validating data, using PI Processbook. Error rate is effectively 0%. End result: more granular, and more ACCURATE inventory data.

14. 14 © 2008 OSIsoft, Inc. | Company Confidential To What Do We Owe Our Good Fortune? Enterprise Agreement (EA) –Effectively eliminates the time spent “counting licenses” –Permits us to expand our PI server grid, turning small satellite sites into full PI sites for the simple cost of harware. Ideal for small sites who expand beyond their WAN bandwidth to Midland. –No more tag limits. (!) This seems small, but licensing/cost based on tag limits was a very large headache. The upside: we build pretty much every tag out there on the control system(s). The downside: we build pretty much every tag out there on the control system(s).

15. 15 © 2008 OSIsoft, Inc. | Company Confidential Big Brother is Always Watching, Comrades Managed PI (mPI) –Round-the-clock monitoring by the OSIsoft NOC (Network Operations Center) –The alert notes sent to Dow Corning can be specially formatted to auto-generate tickets in our problem management system (Service Center) –Single point of contact – one person who can hear all your hopes, dreams, and sleep deprivation-induced nightmares about the PI system.
