  1. Statistical Quality Control Before things go wrong in the Chocolate Milk Factory

  2. At OSI we’re SERIOUS about our chocolate milk

  3. When things go wrong we say“Oh My Goodness!!” Wouldn’t you?

  4. Quality Drivers • Customers They want a quality product, time after time • Process Knowledge Process Flow, Equipment, Measurements, Causes • Experience Operators, QC Staff, Process Experts

  5. Tools for the Quality Program • ProcessBook and PI-SQC • System Management Tools • PI Server • PI Application Framework • PI ACE

  6. Using the PI System • Model the process using the Module Database or Application Framework • Module DataBase Editor • Application Framework Explorer Why? You need the model. It’s a framework for applications that expand the power of PI.

  7. Model Basics Model Equipment Application SQC Chart

  8. SQC Model in ModuleDatabase

  9. SQC Model in Application Framework

  10. Using the PI System • Model the process using the Module Database or Application Framework • Store Process and Quality measurements • PI Interfaces • DataLink • Tag Configurator • PointBuilder

  11. Using the PI System • Model the process using the Module Database or Application Framework • Store Process and Quality measurements • Create and Manage Real Time SQC Alarms • SQC Alarm Manager • Tag Configurator
