  1. RMSAWWA/RMWEA 2002 ANNUAL CONFERENCE Reducing Operation Costs Through SCADA System ModernizationTom Haensel, P.E., Burns & McDonnell Engineerng, Inc.Jan Toniazzo, Treatment Operator, Left Hand Water District

  2. Agenda • Left Hand Water District Overview • SCADA Definition • SCADA Modernization Planning • Implementation • Economic Advantages • Questions

  3. Left Hand Water District

  4. SCADA Defined What is SCADA? • Supervisory Control And Data Acquisition • One Supervisory Controller (Master) • Multiple Sub-Controllers (Slaves) • Possible Sub-Master Controllers

  5. SCADA System Architecture Water Treatment Plant Master PLC Slave PLC Sub-Master PLC Control Valve Network, Fiber Optic, or Phone Line Slave PLC Slave PLC Slave PLC Slave PLC Pump Station Filter Control Water Tank Pump Station Printer Operator Workstation

  6. SCADA Modernization Planning GOALS • Graphical Representation of Entire System • Continuous Information at Operator Workstations • Automatic Control • Remote Control • Alarming/Paging • Trending/Reporting • Easily Expandable

  7. Implementation Hardware • Programmable Logic Controllers (PLC’s) - Standardized on Allen-Bradley SLC and Micrologix controllers

  8. Implementation Hardware • Programmable Logic Controllers (PLC’s) - Standardized on Allen-Bradley SLC and Micrologix controllers • MAS/MDS radios and modems for Radio Communication

  9. Implementation Hardware • Programmable Logic Controllers (PLC’s) - Standardized on Allen-Bradley SLC and Micrologix controllers • MAS/MDS radios and modems for Radio Communication • Mille Research modems for Phone Line Communication

  10. Implementation Software • Standardized on Rockwell Software • RSLogix for programming • RSLinx for communications • RSView for Operator Interface • RSMessenger for Alarm Paging • LapLink Software allows connection to operator workstation from a remote computer through a dial-up modem

  11. Implementation Expandable and Flexible • System must be easily expandable • Implement additional sites without plant shutdown • Allow for additional I/O and control philosophy changes • System must be flexible • Allow for a variety of communication interfaces • Allow for a variety of instrumentation

  12. Economic Advantages • Implementation of “On-Call” shifts

  13. Economic Advantages • Implementation of “On-Call” shifts • Reduced Operator Travel Time

  14. Economic Advantages • Implementation of “On-Call” shifts • Reduced Operator Travel Time • Greater Speed, Accuracy, and efficiency

  15. Economic Advantages • Implementation of “On-Call” shifts • Reduced Operator Travel Time • Greater Speed, Accuracy, and efficiency • Increased Reliability

  16. Economic Advantages • Implementation of “On-Call” shifts • Reduced Operator Travel Time • Greater Speed, Accuracy, and efficiency • Increased Reliability • Reduced Maintenance

  17. Economic Advantages • Implementation of “On-Call” shifts • Reduced Operator Travel Time • Greater Speed, Accuracy, and efficiency • Increased Reliability • Reduced Maintenance • Safety and Security

  18. Questions THANKYOU! Tom Haensel, P.E., Burns & McDonnell Engineerng, Inc.Jan Toniazzo, Treatment Operator, Left Hand Water District
