Extending the Reach of your SCADA
with low data rate satellite technologyGeoffrey Bruce-Payne
Business Development ManagerApril 2013

Overview
SCADA via satellite, in action
LDR satellite provides reliableand cost effective connectivity
ROI is all about the approach
CONFIDENTIAL 3
The Five Big Questions
WHY control and acquire data?
WHAT data is needed?
WHEN is the data relevant?
WHO generates the data?
WHERE does the data go?
And HOW it all fits together…

Why Control and Acquire Data?
Alert & react: safety/production issue
Diagnostics: proactive maintenance
Trending: operational planning
Detailed analysis: operational tuning
Identify the fundamental problem you need to solve.

Event Response
Pipeline integrity Rectifier voltage
Exercise sequence
Business continuity Shutdown → Dispatch
Rapid first time fix
Site security Door, proximity alerts

CONFIDENTIAL 6
Flow Metering and Valve Control
Trending data Hourly PVT
Valve control Local/automatic
Manual/remote
Operational efficiency Reduce site visits
1Why Control and Acquire Data?
CONFIDENTIAL 7
Automatic Meter Reading
Rural water metering Accurate, timely billing
Leak detection
Multi-year battery life; low maintenance
Small footprint
Fracking consumption

Weather Monitoring
Monitor weather conditions near mines Predict highest yields
15-minute updates
Web access for meteorologists

CONFIDENTIAL 9
What Data is Needed?
Measurements Pressure, Voltage, Temperature
States (open/closed, on/off)
Control thresholds
Fault codes
Timestamp

CONFIDENTIAL 10
Bit-wise Data Encoding
Resolution: units, scale, range
Simplicity vs. Efficiency
Transport overhead
How efficiently can the information be encoded?
2What Data is Needed?
Meas#1 Meas#2 Meas#3Ind.ProtocolNetwork Protocol (IP)
Opportunity to optimize
CONFIDENTIAL 11
When is the Data Relevant?
When a problem happens
When something changes
Few times per day
Every few minutes or seconds
Data Requirement = Size * Frequency

CONFIDENTIAL 12
SCADA Architectures
Modbus vs DNP3 vs something else…
RTU data model (# queries, encoding)
System model (polled vs unsolicited)
Unsolicited summary report is most efficient
3When is the Data Relevant?
CONFIDENTIAL 13
Who Generates the Data?
Conventional SCADA: RTU aggregates sensors/meters
Modem connects RTU to Cloud Often requires custom programming
SCADA polls RTU via Cloud Data intensive

CONFIDENTIAL 14
Distributed Intelligence
Optimize: latency, cost, power
Asset gateway Abstracts different types of RTU
Generates optimized data updates
Enterprise gateway Maps optimized data to conventional SCADA
and/or other business systems
Manage high quality data with thin pipes.

Driving Return On Investment
Approach the problem “what do I need” rather than “what have I done before”
Spend a little more time optimizing up-front, to get quicker payback
Evaluate total cost of ownership
CONFIDENTIAL 22
Satellite Beyond SCADA
Occupational Health and Safety
Tracking
Check-in
Driving habits
Workflow automation
Dispatch
Electronic forms
Low cost solutions exist to provide ubiquitous connection to your assets and people.

Summary
Low data rate satellite takes M2M farther
Distributed intelligence lowerscost to bring assets on-net
Use the right tool for the job
Do more with less.
