  2. Telemetry Systems…40-20 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.

  3. …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 – MainlyMimic Panels & DOS Based SCADA

  4. Typical Telemetry Network – Then!

  5. 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 RTU’s • 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 IED’s – 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 RTU’s

  8. Typical Telemetry System Layout SCADA, MES & Information Systems Backhaul Communication Network Monitoring Equipment RTU’s Interfacing & Connectivity Instrumentation & IED’s Security & Access Control Energy Meters Soft Starters Actuators Flow Meters PLC’s
