Resources Control Room & Field Operators Equipment status (i.e. valve, switch) before
manipulating Confirm equipment has been put in
maintenance mode Verbal description of equipment
schematics Compare SCADA status with equipment
indicators Testing or calibrating a measurement or
control element Safety
Danger of miscommunication resulting in maintenance on live equipment
Timeliness Transferring manual data collection to
spreadsheet or the SCADA
Mobility Issues Today
The Rise of Mobile Devices
Number of mobile device users has exceeded workstation users
Customers are rapidly adopting mobile devices to access SCADA information and notifications
Human interaction with mobile devices is fundamentally different than workstations
A new approach for mobile SCADA is needed
General Business Mobility
Big Data Need mobile data monitoring solutions Data sets are large and complex
Large Volume & Growth of Data Growth of video traffic Sensor traffic Other sources of data traffic
High Velocity of Data Increased connectedness Mobile applications Unrelenting time-sensitive traffic

Mobile Workers in the UK 44% not equipping mobile workers properly
Access to required information is limited

Impact to SCADA
Substation IED’s supply a wealth of new information of each distribution asset. Loading Performance Operating status
Strong risk of too much information for operators. May ignore it May be confused by it May make bad decisions because of it
Only provide information that is “actionable” Avoid duplicated information

IIoT Myths
Myths
1. All process control functions will be in the cloud.
2. Field devices will all be talking to each other from all over the world.
3. Enormous amounts of new data will be created.
4. Everything will be wireless
Truths1. IIoT is an infrastructure
Open system Interconnecting intelligent devices
via IP addressing A mixture wired and wireless
2. May be more efficient for moving large data Possibly of moving data to the Cloud Objective is Big Data Analysis May create new useful information Not yet proven
3. On-site control will still be on-site Operation and troubleshooting will not
be done from the cloud.4. Enhancements to mobile devices are
needed. Users and devices need better mobility support
while in motion.source: IIoT insights from Herman Storey– Control Engineering August 2015
The Real-Estate Problem
Early 21st Century Control Room
1980’s Control Room SCADA Information
Controls Rooms have more graphic displays as information has grown in volume and complexity
Mobility means downsizing
What is the Answer?
9
The right information securely presented to the right person at the right location at the right time
The Answer Is ….
Proximity & Location
Services
Geolocation Outdoors Long established for earth
coordinatesGPS adapter on mobile device
Micro-Location IndoorsGeo-tagsNFCQR CodesWi-Fi PositioningEmerging technologies
Proximity Services for Mobile Workers Relying on HMI, SCADA or BMS systems Set of application servers Smart mobile device app
Uses Available Infrastructure Indoor and outdoor positioning services IP based networks
Redefining Mobility
Input to the Mobility Server User’s credentials User’s present location
Output from the Mobility Server Contextual information and controls Tracking of mobile workers and assets

The Mobility
Server
Contextual Logic Engine Associate actions and events to location Deliver SCADA information and controls Links to contextual documentation
Equipment Supervision and Monitoring Industry specific protocols
OPC, Modbus, BACnet, DNP3, IEC etc. Web Services
Archive Location History Include equipment in proximity of location
Securing Mobile SCADA
14
Use cybersecurity best practices with additional mobility validation When entering a zone, validator tags provide
additional identity verification Validation tags must be present for user
access to secured actions Mobility Server
Manages user rights Maintains audit trail
User’s actions User’s locations
Automatic update or revocation of rights Based on real-time location When disconnected user data is not stored
on mobile device
Maintenance responseDispatch most qualified resource Local view of status of equipmentMaintenance records and logs on
for the job at handAutomatic display of HMIBased on equipment proximityParticular value for unstaffed sites
Remote Monitoring & Control
Track of workers locationSafetyEfficiency of dispatch
Simplified commissioning
Spatial relationship of assetsParticularly for geographically
distributed equipmentAdaptive zone controls location and profile of worker
Remote Monitoring & Control
Alarm on restricted zone entrySafetySecurity
There is a need for a new SCADA Mobility Infrastructure The Workstation HMI approach via
browsers is not sufficient Smart mobile devices have built in
capability to detect location Location and user profile enables an
enhanced mobile HMI solution Knowledge of the mobile workers
location and surrounding assets has the benefit of tracking positions
SCADA Mobility Server is critical to the infrastructure Data acquisition via industry protocols Aggregate/process/treat the data Contextual filtering & tracking Control user rights Generate reports & dashboard metrics
