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
