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

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

Left Hand Water District

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

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

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

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

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

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

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

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
