1 SSE Remote Telemetry Unit SSE RTU

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 – Mainly Mimic Panels & DOS Based SCADA

4 Typical Telemetry Network – Then!

5 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.

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 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 SSE Design Philosophy

8 PLCs ActuatorsFlow Meters Soft Starters Energy Meters Security & Access Control SCADA, MES & Information Systems Backhaul Communication Network Monitoring Equipment RTUs Instrumentation & IEDs Interfacing & Connectivity Typical Telemetry System Layout

9 SSE RTU-12 Features Instrumentation & IEDs: A wider choice of instruments. Different interface signals: 4-20 mAmp, mAmp Volt & mVolt. Frequency & pulses. Micro Processor based instruments got more an more popular. Intelligent Electronic Devices (IEDs) IEDs with Direct communication capabilities. Running different protocols, At different baud rate, Using different communication mediums. IEDs got more and more popular, but started posing more and more interfacing challenges. PLCs ActuatorsFlow Meters Soft Starters Energy Meters Security & Access Control

10 Interfacing: Discrete signals via conventional cabling IEDs supported on a wide variety of interfacing and communication networks RS-232 RS-485 Ethernet LAN Etc RTU-12 Equipment supports these mediums simultaneously PLCs ActuatorsFlow Meters Soft Starters Energy Meters Security & Access Control SSE RTU-12 Features…cont.

11 Communications Backhaul: Communication between remote RTUs and Master SCADA computers. Protocols: DNP-3 Slave. IEC Modbus. DF-1 Enermax. Etc. Running different communication mediums: Analogue Radio. Data Radio. Dial-Up. SMS / GPRS / 3G. Fibre Optic. LAN Wireless LAN. Wi-Max Satellite. Etc. SSE RTU-12 Features…cont. PLCs ActuatorsFlow Meters Soft Starters Energy Meters Security & Access Control

12 SSE RTU-12 Features…cont. RTU-12 Summary: Monitor discrete I/O. Interface simultaneously with IEDs on multiple protocols and on multiple mediums. Backhaul comms interfacing on multiple protocols and on multiple mediums. Data concentrator and manager. Configurability vs Programmability. PLC like programming for local or distributed control.
