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.

What Data is Needed?

Measurements Pressure, Voltage, Temperature

States (open/closed, on/off)

Control thresholds

Fault codes

Timestamp

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

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
