  3. Integrated Process Controllers What do they provide? Low Installed Cost • Low Equipment Cost • Minimizes purchase cost • Integrated Process and Logic Control • Shortens design time • Pre-formatted Color Displays • Reduces HMI Development Time • Graphic PC Configuration • Reduces Configuration Time • Automatic Tuning and Fuzzy Logic • Cuts Startup Time

  4. Integrated Process Controllers What do they provide? Reduced Operational Cost • Tighter Process Control • Better accuracy & repeatability • Autotune Minimizes Process Deviations • More time “on-spec” • Less energy usage & product scrap • Recipe Handling • Fast, accurate product changeover • Integrated Control and OI Integration • OI replacement without software reload • Reduced process downtime

  5. Integrated Process Controllers What do they provide? Reduced Life-Cycle Engineering Costs • Configuration Changes via Common Engineering Tool • Single configuration tool for Controller & OI • Reduced configuration errors • Reduced troubleshooting/startup time • Common text and configuration file simplifies validation
