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 –

Stretching the Limits of the PI SystemStretching 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.

And the Best Way to Improve Your SystemAnd the Best Way to Improve Your System

TRAIN THOSE OPERATORS/ENGINEERS (you can skip the engineers)– Seriously, users will surprise you with a) the stuff they figure

out, or b) the stuff they ask YOU to accomplish.

Seriously, skip the engineers:

To What Do We Owe Our Good Fortune?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).

Big Brother is Always Watching, ComradesBig 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.

Application Frameworks– The new structure of PI will permit us to achieve the

following:• Plant-scale material and energy balances• Further integration with SAP using Sigmafine in

conjunction with Rlink
