PI Application Framework Introduction

• What does PIAF Do For Us?– Provides Infrastructure

• Implements Infrastructure Common to Most Applications• Shares Aggregation• Shares Business Logic• Promotes Reuse (across facilities and industries)

through n-tier architecture

– Separates Development from Configuration • PI Point Paradigm

– Implement / Manages Features Needed by All Applications in this Problem Space


Key Concepts

• Next, we look at many of the key concepts behind the PI Application Framework


PI AF Server


PI AF Database


Source Control Paradigm


Element Templates


Element Types


Ports


Catagories


Elements


Element Attributes (Values)


Transfers


Units of Measure


Tables


Models


Layers


Connections


Cases


Managed Code (.NET)

• AFSDK and Server Code base developed in C#– Remoting– Robustness– Development Efficiency– COM Interoperability

• Used by Common Controls, ProcessBook, etc.


Plug-Ins


Data References

• Demo


Time Rules

• Demo


Analysis Rules

• Demo


Context

• Time Context– Batch*– Case– Time Range– Time– None

• Model Context• Analysis Context• Presentation Context (UOMs)


Common Conceptions and Misconceptions

• The PI Application Framework Replaces Prior Development Toolkits– Misconception: The PI Application

Framework complements the PI SDK (and PI Server) adding new functionality and behavior in the realms of information organization (aggregation), topology and shared business logic



• The PI Application Framework is Built on .NET Technology– Conception: The PI Application Framework

is built from the ground up as a managed class library.



• The PI Application Framework Replaces the Module Database– Misconception: The PI Application

Framework uses the Module Database just as any other application might use the Module Database.



• The PI Application Framework is THE PI Development Environment– Misconception: The PI Application

Framework provides services and an SDK for solving specific problems in specific problem domains.



• The PI Application Framework is Sigmafine 4.0– Misconception: The next major release of

Sigmafine, 4.0, is a solution built on the PI Application Framework, implementing solution specific schema (templates), business logic in the form of many plug ins,


Developer Roadmap

• Methodology for Developing with the PI Application Framework

• Developing Sigmafine 4.0

• Resources for Developing with the PI Application Framework


Developing with the PI Application Framework

• Define Aggregation Schema– Create Element Templates

• Define Logic– Time Rules, Data References, Analysis Rules

• Define Presentation– Process Book, Data Link, ICE Integration– Custom Reports– Custom Applications

Using the PI Application Framework

• Configure Elements• Configure Models

– Configure Element Connectivity/Topology– Configure Analysis

• Run Cases– Run Analyses

• Configure Presentations– Build Reports, Displays, etc.

PI Application Framework Developers Roadmap

• The following section outlines the requirements and resources for PI Application Framework Development Early Adopters and Beta Users


PI Application Framework Development Dependencies

• Development PI Server 3.3 SR1

• PI SDK (minimum or exact version dependent on PIAF)

• PI Application Framework Beta– Open beta begins in December 2002


PI Application Framework Development Dependencies

• PI Client Application Integration– Process Book 3.0 Beta (availability TBD)– PI AF Data/Modeler Add In for PB– PI AF Add In for Excel


PI Application Framework Development Resources

• What’s Installed in the Developer Version?– AF Server– AF SDK

• Interoperation DLL’s and Public Assemblies• AF Common Controls

– Online Help– Reference for PI Application Framework

Object Model

mk:@MSITStore:C:%5CProgram%20Files%5CPIPC%5CHELP%5CAFSDKRef.chm::/Hierarchy.html


PI Application Framework Development Resources

• What’s Installed in the Developer Version? (Continued)– Utilities– Wizards– Tutorial

• Chocolate Milk Factory

– Samples• Time Rules• Data References• Analysis Rules


Digging In

• Developing Plug-Ins– Plug-In Wizards– Installing Plug-Ins– Sample Plug-Ins

• CMF Tutorial– See Code?

• Graphical Model Building– PI ProcessBook 3.0 Demo


PIAF Plug In Wizards

• The PI Application Plug In Wizards for Visual Studio.NET jump start the development of Time Rules, Data References and Analysis Rules.

• Wizards are available for both C# and VB.NET.


PI AF Plug In Wizards (Demo)


Installing a Plug In (Demo)

• The PI Application Framework Server “listens” for changes to the Plug-Ins directory and dynamically adds conforming Plug Ins to the list of known plug ins.


Time Rule Sample

• The Time Rule Sample covers the basic steps required to implement a custom Time Rule Plug In for PI Application Framework.

• Covered in Chapter 4 of the PI Application Framework Users Guide


Data Reference Sample

• The Data Reference Sample covers the basic steps required to implement a custom Data Reference Plug In for PI Application Framework.



Analysis Rule Sample

• The Analysis Rule Sample covers the basic steps required to implement a custom Analysis Rule Plug In for PI Application Framework.



CMF Tutorial

• The Chocolate Milk Factory Tutorial covers most of the basic aspects of programming the PI Application Framework.– Covered in Chapter 3 of the PI Application

Framework Users Guide (included in the handout.)

– Separate CMF Simulator Available*


CMF Tutorial


CMF Tutorial

• DEMO– Create PI AF Database– Create CMF– Run the CMF– Look at CMF via ProcessBook and

AFExplorer– Review Code Behind CMF


CMF Tutorial

• Create– Create Units of Measures– Create Categories– Create Templates (Schema)– Create Derived Elements– Create Model– Add Elements to Model– Add Element Connectivity– Create Model Analysis


CMF Tutorial

• Run– Create Case– Run Case


CMF Tutorial

• Remove– Remove Model– Remove Transfers– Remove Element Templates

• Removes Derived Elements

– Remove Categories


Configuration Utilities

• What About Configuration Utilities?– Much of what is demonstrated in CMF will typically

be accomplished using bulk and/or interactive configuration utilities.

– Bulk configuration will be through XLM documents– Interactive configuration will be through Excel (ala

Tag Configurator) or ProcessBook (Element Configuration and Model Building)


Building a Model Graphically

• ProcessBook 3.0 with the PI Application Framework Add-in (DEMO)


Call to Action• Application Developers

– Sign up for beta program– Begin porting or developing applications

on the PI Application Framework

• Corporate Developers– Sign up for beta program– Begin design process for integrating PI Application

Framework

• IT / Administrators– Plan resources - white papers to be provided on

beta website


Call to Action• All Users

– Start to think about and identify • Organizational / Structural Abstractions
