Agenda


4

Typical World of Industrial Devices

• Hierarchical architecture

• Devices / products / controllers connect locally to BMS/SCADA

• Central visibility / alarms / dispatch through BMS/SCADA


5

Some Limitations of BMS

• Adding new functions to BMS is complex

• Device information and insights are lost as data is filtered and consolidated to BMS

• Device vendors (OEMs) do not have visibility to their products and cannot be proactive– IT will not open up access to individual controllers

(security concerns)

– Even if access to BMS is available, only a subset of data is available

• And only 20% of facilities have a BMS


6

The Brave New Consumer IoT World

• Non-hierarchical architecture, smart and independent devices• All have their own applications and cloud point-of-presence• Independent of a “central management” system


7

Cloud-Based “Orchestration”

Controls lights, switches, and thermostats with compatible WeMo, Philips Hue, Samsung SmartThings, Wink, Insteon, Nest, and ecobee smart home devices


Sort of a “mini BMS” for yourhome!

8

• Create ONE consolidated Facility Cloud Point of Presence (PoP) for the facility

– Central and secure access point for all your vendors (OEMS), so they can be proactive and collaborate with facility manager

– Feeds data to enterprise’s IT/business applications– Enables new “orchestration” applications that supplement BMS

Consumer World Ideas for the FM

If the FM has a BMS at the facility

• Adding a cloud-based “mini BMS” for that facility• Using the Facility Cloud Point of Presence to feed the new cloud-based BMS

And if no BMS at facility (but BACnet devices), also consider

The Facility Cloud is the “blue collar cloud”

§ Does “dirty” work of field device connection, and security

§ Middleware and staging layer for device data

Where does a Facility Cloud fit?

Provides secure device access§ To device vendors for visibility§ To routine business processes like ERP

§ To new BMS / BEMS / OrchestrationApplications … which can drive actionthrough vendor-provided controls

16

• Do what all the consumer device makers do …• Implement your own Vendor/OEM Cloud Point of Presence (PoP)!

– Secure way for to “access” own devices– Vendor can be proactive on support and insightful on operation

Consumer World Ideas for the OEM

Instead of waiting for facility manager to build a cloud and give you access ….

Or waiting for facility’s BMS to provide data to you ….

Or not even knowing where your products are …..
