About Kepware


What is IIoT?

Industry

More diverse, longer lasting, bigger

Exhibit A - Toothbrush

5

• Monitor how well you’re brushing

• $125.00 retail


Exhibit A – Technology Stack

6


The 15 Trillion $ Question

If I can create a business model for connecting

a toothbrush, why can’t I create a business

model connecting this?

7


The technology stack is similar

8


The Big 50

Over 50 billion things on the edge by 2020

Don’t worry you have 5 years

Data


5 years…

To find 50 billion things

To configure 50 billion things

To collect, manipulate, and store their data

To find their VALUE


Faster Decisions

Process visibility & faster decision making

Data mash-ups, reporting, and visualization


Analytics

Predictive analytics & number crunching


Open Data

Shared data across sites, companies, and supply chains

Remove data silos

Demand response


New Business Models

How do we realize this value?

“What got us here won’t get us to where we

need to go.”


What is our edge?

It’s where our data comes from


And it takes many forms

Equipment like this. It could be far or near


We connect to the edge

Connect to this


We connect to the edge over

Connect over these

Serial

Ethernet

Radio

Cellular

Satellite

And more…


We speak to the edge using

Speak using

Modbus

Ethernet I/P

S7

DNP3

Bristol

SNMP

ROC

61850

BACnet

And many, many more


Data from the edge goes to

Data goes to

HMIs to visualize

Historians to store and trend

Alarm Management Systems to notify

Workflow solutions to integrate

Predictive analytics to fix

ERP to plan

Excel to… what are your doing in Excel?

And more…


And we have names for this

We call it

SCADA

M2M

Control Systems

Operational Networks


And now it’s called IIoT, right?

• Larry Ellison – CEO of Oracle

• “They don’t call it the Internet

anymore, they call it cloud

computing”


IIoT is Technology driven

• 20 billion transistors on a chip

• Apple iPhone

• 3G/4G/LTE connectivity

• Amazon - computing as a service

• Google – mass data storage

• HTML5

24


Technology is moving fast

25


Where do I start?


Look ahead into IT

• IoT Platforms are hungry for data Big Data

Alarms/Workflow

Analytics

Data Mashup/Visualization

How do we get data to them?


Will we rip & replace?

28


Overlay an IoT Gateway

29


Connect to anything

Everything is different, so connect and make it all look the same


Give the Edge IQ

Too much data, so we condition it

Cloud is unreliable, so make local decisions (edge analytics)

The internet is unreliable, so store & forward the data


Translate to anything

Translate to AMQP, MQTT, DDS, OPC UA, etc


Iterative Approach


IoT Protocols

Asynchronous Message Queuing Protocol (AMQP)

Message Queue Telemetry Transport (MQTT)

Data Distribution Services (DDS)

Constrained Application Protocol (CoAP)

OPC Unified Architecture (UA)


IT Protocols: Push vs. Pull

Client/Server or Master/Slave

Client connects to the server (firewall)

Client polls for data

Scale it to 50 Billion?

Client

Server/Device Server/Device Server/Device


IT Protocols: Push vs. Pull

Pub/Sub

Everyone connects to a broker

Publish data to subscribers when available

Easier to scale, firewall friendly

Call to Action

You can play with IIoT today using the data you’re already collecting

via you’re SCADA & Controls networks

You can play around with gateways and IoT Platforms for very little

upfront cost or risk
