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.

…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

Typical Telemetry Network – Then!

Scada Application

Evolution of Technology

• Driven by two main influences

1. 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.

2. From Technology offerings (Pushing forces):

• New technologies offer better and smarter solutions

• Faster processing power.

• More robust communication networks.

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

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
