  1. The Upcoming PI-DataLink 3.x By Jason King and Ling Mok

  2. PI-DataLink Basics • What is PI-DataLink? • PI-DataLink is a PI client used to transfer data for PI tags between PI servers and your spreadsheet. • Spreadsheets supported: Excel and Lotus 1-2-3

  3. New Features for Datalink 3.x • SDK Based • Time Zone • Advanced Event Information (Quality Bits) • Questionable • Substituted • Annotated • Enhanced Calculation Features

  4. PI Tag Calculation Type The Old PI-DataLink • Calculations accepts one tag as a data source • All Calculations are Time Weighted • Except for Mean Output

  5. Enhanced Calculation Features • Advanced Data Source Specifications • Event Weighted Calculations • CountTrue • Naturally Sampled Expression Calculations

  6. Advanced Data Source Specifications • PI expressions (i.e. TagA + TagB) • Data Source can be data directly from spreadsheet • Filter Expressions

  7. Accumulation Interval X B B X A A Total = X +X A B Event Weighted • Total • Sum of compressed values on curve during time period

  8. Condition True B A # events = 2 CountTrue • Calculates number of events in condition

  9. Naturally Sampled Naturally Sampled Expression Calculations • Natural Sampling • Evaluate expression at archived values as opposed at evenly spaced intervals Evenly Sampled

  10. Data Source Calculation Type Filter Calculate New Calculated Data Flow Diagram • Data flow is as follows: Output

  11. Examples of New Complex Queries • What is the average flow rate of flow1 while pumpA in “Auto” state? • What is the time weighted total of the sum of flow 1 and flow 2? • How many times was flow1 below 100 gal/min?

  12. Calculation Type Output The New Advanced Calculated Data Data Source

  13. Demo Time • Time for the FUN Part!
