Transcript of "SCADA System Design & Operation"

  1. 1. SCADA System Design & Operation A Briefing By Jim Mimlitz Heartland Pump Rental & Sales Open House 04 November 2010 RI wireless-telemetry.com © 1995-2014 COPYRIGHT NAVIONICS RESEARCH, INC. ALL RIGHTS RESERVED.
  2. 2. RI wireless-telemetry.com Where We Work… Our Clients… IOWA ILLINOIS 16 29 15 49 45 23 18 40 20 59 32 28 54 14 INDIANA 60 19 43 21 22 36 17 38 35 27 51 50 07 31 56 34 53 08 46 10 13 MISSOURI 04 09 03 02 61 05 58 37 11 41 24 01 25 39 12 26 33 06 44 55 57 42 47 48 KENTUCKY 30 ARKANSAS TENNESSEE © 1995-2014 COPYRIGHT NAVIONICS RESEARCH, INC. ALL RIGHTS RESERVED.
  3. 3. RI wireless-telemetry.com Why SCADA?… SCADA = Supervisory Control And Data Acquisition With A SCADA System, Transit-Time Is Substantially Reduced. Overtime Is Minimized. With An Alarm System Integrated With Smart-Phones, The Detection Of Costly System Faults Is Accelerated. Physical Security At Unmanned Facilities Is Enhanced. Quality-Of-Life For The System Operators Is Improved. System Documentation Is Automated and Centralized. Access Is De-Centralized. A SCADA System Substantially Reduces Operational Costs And Increases Overall Industrial System Reliability. © 1995-2014 COPYRIGHT NAVIONICS RESEARCH, INC. ALL RIGHTS RESERVED.
  4. 4. RI wireless-telemetry.com Why “Wireless”?… More Reliable And Maintainable Than Leased Line Systems. Operations Not Dependent Upon A Telecommunication Utility. Less Susceptible To Power/Lightning Surge Damage. Recurring Leased Line Charges Are Avoided. © 1995-2014 COPYRIGHT NAVIONICS RESEARCH, INC. ALL RIGHTS RESERVED.
  5. 5. RI wireless-telemetry.com What Does A Typical SCADA Panel Look Like?...
