Programmatic InterfacesActiveX.

OSI and ActiveX based interfaces.

Tools for applicationsOSI Products. Controls, applications

User’s applications

Introduction, continued

PI Module DatabaseAdd structure to the PI Data Archive

“Display Time” data source resolution

PI Batch DatabaseModel and store batch data

Map batch data to PI Data Archive

Support ISA S88 and beyond

Purpose

Batch IndustryDemands on equipment modeling

Numerous, similar equipment entities

Produce a wide range of products

Moveable, configurable equipment

Purpose

All industries can benefitAdd Structure to the PI Data Archive

Add organization through PI Point grouping

Controllers

Arrays. For example profile points

Complete hierarchical model

Used to implement consistent naming convention

Does not enforce a particular hierarchy

Does enforce order

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

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

PIModuleDB Summary

Easier access to PI Data Archive

Model to fit users requirementsFor example, production requirements vs. maintenance requirements

Model supports changes through time

Module definable attributesPIProperties collection

Features For Release 2

Module TemplatesRe-use of common module configurations

Also hierarchical

InheritanceChanges to Module template propagated through derived modules

PI Alias DefinitionsTemplate of alias definition with default point attributes
