PI Performance Equation Syntax Mathematical Functions and Operators Expressions can use… Mathematica l operators Mathematica l functions + cos() exp() - sin() * tan() / log() ^ log 10() And more… abs() int() atn() sqr() sgn() Copyright © 2010 OSIsoft, Inc. 36

PI Performance Equation Syntax Built-in Functions l Examples of built-in functions: • % of time tag has good values Pct. Good() Range() • Range of min to max St. Dev() • Time-weighted standard deviation Tag. Avg() • Time-weighted average Tag. Mean() • Event-weighted average Tag. Max() • Maximum value in period Tag. Min () • Minimum value in period Tag. Tot() • Time integral over a period Copyright © 2010 OSIsoft, Inc. 37

Operators in Performance Equation An expression can use If-Then-Else, relational and logical operators l l Syntax: IF expr 0 THEN expr 1 ELSE expr 2 Example: IF ‘Tag 1’ >= 50 AND ‘Tag 2’ < 125 THEN “under limit” ELSE “good” Copyright © 2010 OSIsoft, Inc. 38

Conclusion “By using PI, we have been able to see what we guessed was happening. We have been able to validate our ideas and turn them into substantive savings. In our case, 10% of our operations budget. ” Chilkoot Ward Director of Utilities University of Alaska (Power Generation) Copyright © 2010 OSIsoft, Inc. 49
