Telemetry Systems40-20 Years Ago

• Rural Pumping Schemes Controlled by hand
• Urban Schemes Controlled by Relay Logic
  Instrumentation
• Very Basic Telemetry Systems Hard Wired with
  Mimic
• Radio Telemetry Starting to emerge for remote
  control.

15 to 20 Years Ago

• Demand for Operational Function Alarms
  Remote Control
• Slow Radios (300 Baud) Installed Limited Data
  Throughput
• Cable Replacer Type Telemetry System
• Control Relay Logic/Basic PLC
• Small Amount of Data Mainly Basic Alarming
  Limited Control
• Master Station Mainly Mimic Panels DOS Based
  SCADA

Scada Application
Evolution of Technology

• Driven by two main influences
• From Client Side (Pulling forces)
• Plants and distribution networks got more
  complex.
• The demand for more information at a quicker
  rates.
• Better / Faster service delivery.
• From Technology offerings (Pushing forces)
• New technologies offer better and smarter
  solutions
• Faster processing power.
• More robust communication networks.

6
Modern RTUs

• Compact more I/O with smaller footprint
• Connect to all wide area networks compatible
  with new IP based networks
• Intelligent PLC Based processing capabilities
• OPC Compliant Software open standard for
  industrial applications
• Remote Diagnostics Network wide fault finding
  and configuration tools
• Support for IEDs protocol support for
  intelligent devices
• Protocol Standardization

7
SSE Design Philosophy

• Client Requirement driven.
• Technology driven.
• Follow well established engineering practises.
• Hardware Software are modular in design.
• To design products that are
• Economical
• User friendly
• Open
• Compatible
• Expandable
• Always backwards compatible to older version RTUs
