  1. PI Module Database Ken Coates, Jon Peterson OSI Software, Inc.

  2. Introduction • PI Server Databases • Programmatic Interfaces • ActiveX. • OSI and ActiveX based interfaces. • Tools for applications • OSI Products. Controls, applications • ISV and system integrators • User’s applications

  3. Introduction, continued • PI Module Database • Add structure to the PI Data Archive • “Display Time” data source resolution • PI Batch Database • Model and store batch data • Map batch data to PI Data Archive • Support ISA S88 and beyond

  4. Purpose • Batch Industry • Demands on equipment modeling • Numerous, similar equipment entities • Produce a wide range of products • Moveable, configurable equipment

  5. Purpose • All industries can benefit • Add Structure to the PI Data Archive • Add organization through PI Point grouping • Controllers • Arrays. For example profile points • Complete hierarchical model

  6. OSI Brewing • Demonstrate the Module Database • Pre-beta PI 3.3 • Top-down design approach • Start with the big picture • Drill down into the details

  7. Enterprise: OSI Brewing, Inc. Site: Cleveland Area: Production Line: Phil’s Pilsner Line: Mark’s Stout

  8. PI SDK Object Model Server PIModuleDB PIHeadings PIHeading PIModules PIModule PIHeading PIAliases PIAlias PIProperties PIProperty

  9. PIHeadings • Used to implement consistent naming convention • Does not enforce a particular hierarchy • Does enforce order

  10. PIModules • PIModule is the fundamental equipment element • Comprised of: • Name • PIHeading: Module's hierarchy • PIAliases: Collection of Data sources • PIProperties: User/Application specific configuration data • PIModules: More equipment collections

  11. FCML101 F9CCFA79-B356-11d3-BA4B-F0C04F428C95ControllerFlow controller, ML-101 Version 24PIAdmin 22-Sep-19993-Oct-1999 PIAliases PIProperties PIModule

  12. PIAliases • PIAlias maps a common name to a PI Point • Used to associate data with modules or equipment • All PIModules have a collection of PIAliases

  13. FCML101 PIAliases PIAliases Alias Data Source Value LCMS101.pv Setpoint LCMS101.sp Output LCMS101.out

  14. PIProperties • Set of Name-Value pairs • Stored in a VARIANT; therefore can hold nearly anything • User or application definable properties • Non-time series data associated with module

  15. FCML101 PIProperties PIProperties Name Value Instrument Engineer John Doe Last Tuned 22-Nov-1996 Type PID

  16. Demonstration • Configuration Tool • Microsoft Management Console Based • Consistent configuration interface

  19. Unit: Brew Kettle

  20. Table View of Brew Kettle

  21. Brew Kettle “Sub-Modules” • The PIModules used to add collections of modules. • PIModule: “Controllers” • Temperature Controller • Level Controller

  22. Brew Kettle Demonstration • Add the brew kettle to hierarchy • Add the controllers to the brew kettle

  23. Unit: Brew Kettle

  24. Brew Kettle, Phil’s Stout Line • Nearly identical to Brew Kettle on Mark’s Stout Line • References different data sources • Demonstration: Display time resolution of data sources

  25. Historize Equipment Changes • Just like Process Data • Time stamp and Value • Keep track of modifications • New Instruments and New Units • Changing Product Information • Updated Specifications • New Products / Raw Materials • Database Driven Applications

  26. Adding a New Instrument Time (values) Brew KettleEffectiveDate: 01-Jan-00 Brew Kettle EffectiveDate: 01-Mar-00 Aliases Aliases Thermocouple 1 Thermocouple 1 Thermocouple 2 Thermocouple 2 Thermocouple 3 Thermocouple 4

  27. Enhanced Brew Kettle

  28. Demonstration • Excel spreadsheet report • Correctly resolving equipment in place for report period

  29. PIModuleDB Summary • Easier access to PI Data Archive • Model to fit users requirements • For example, production requirements vs. maintenance requirements • Model supports changes through time • Module definable attributes • PIProperties collection

  30. Features For Release 2 • Module Templates • Re-use of common module configurations • Also hierarchical • Inheritance • Changes to Module template propagated through derived modules • PI Alias Definitions • Template of alias definition with default point attributes

  31. Release Schedule • Leveraging foundation of PI SDK 1 • Harry Smith • Bill Vaughan • Leveraging foundation of PI 3.x • Richard Beeson • Rulik Perla • Four Developers (4 fold increase!) • Configuration tools and controls • Richard May • Prabal Acharyya • ActiveX and Server Components • Ken Coates • Jon Peterson

  32. Release Schedule • Beta Second Quarter 2000 • General beta with beta controls and configuration tools • Release Third Quarter 2000 • PI 3.3 • PI SDK 1.1
