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 (PLCs) -
  Standardized on Allen-Bradley SLC and Micrologix
  controllers

8
Implementation
Hardware

• Programmable Logic Controllers (PLCs) -
  Standardized on Allen-Bradley SLC and Micrologix
  controllers
• MAS/MDS radios and modems for Radio Communication

Implementation
Hardware

• Programmable Logic Controllers (PLCs) -
  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
