End–user responses

General

Q: Briefly describe the application including information on any pre-existing control system.

This end user is implementing the Smart City project using IoT enabled devices to remotely monitor its fixed and moveable assets as well as infrastructure. The Smart City project was implemented in parallel with an existing Adroit SCADA system, which monitors and controls the end user’s water systems and services.

Q: What was the primary motivation for the project?

This project was started with a view to mitigate risk and to take advantage of the new digital trend for better service delivery to its customers.

Q: What were the main goals established for the project?

Demonstrate reliability and endurance in live environments of IoT enabled devices. A number of pre-defined devices were chosen to achieve the following goals:

• Detection of manhole tampering.

• Notification of access to underground infrastructure.

• Water metering.

• Pipeline pressure monitoring.

• Asset tracking and notification with geo-fencing.

Data collected by the IoT sensors is applied in ways that benefit and add value to the current scada system.

Q: In the procurement decision-making process what were the primary considerations that influenced the product selection?

Adroit Technlogies exstensively tested and developed its IoT platform using Visio sensors and the Sqwidnet backend. Although Adroit Technologies is not reliant on one particular vendor or IoT product, both these companies provided excellent services and products.

Q: What Project Management principles were employed to mitigate risk, ensuring the project came out on time and within budget?

The project scope was developed using the Project User Requirements Document and Functional Design & Specifications Documentation. Scada engineering was covered by Adroit Technologies and installation of the sensors was outsourced.

Licensing, maintenance and support

Q: What licences have been purchased for this particular application?

Adroit Smart UI.

Q: What upgrade agreements are in place on this particular application?

Adroit Groupwide Agreement.

Q: How is after-sales support handled on this application?

As part of an SLA agreement a 24 hour support resource is available as well as remote access for trouble shooting and diagnostics. As reliability is a core requirement for the Smart City project, a weekly inspection is scheduled, and an offsite backup is kept as part of the SLA.

Q: Do you have a documented process in place to manage, test and install OS and scada system software patches?

A complete CRM system has been implemented to augment the support of Adroit Smart UI. Microsoft Team Foundation has also been implemented as part of the quality assurance. Once the project team has a complete understanding of the end users requirements a functional design specification (FDS) was created for the implementation of the solution.

This FDS document includes (but is not limited to):

• Project standards.

• Product upgrades.

• Long term viability.

Integration, reporting and archiving

Q: Is the scada system integrated onto an intranet or the Internet?

One of the Smart City project requirements was easy access to information. To facilitate this Adroit implemented a ‘traditional’ scada interface as well as a geographic information system (GIS) interface and Adroit Performance Anywhere, which accesses the scada’s data via HTML5 web services. In addition, the Adroit Secure Mobile Gateway solution has been implemented to allow secure access to the scada from outside the company IT infrastructure.

Q: Does the system include or interface with an expert system?

N/A.

Q: Is the system integrated with an MES / ERP or other management reporting or control system?

N/A.

Q: Has any GIS (Geographic Information Systems) functionality been configured in the application?

The Adroit Smart UI has a GIS interface, which allows added intelligence to map overviews by dynamically or statically defining map nodes and geo-areas. In the case of the Smart City project, each node was assigned to an IoT device. The GIS interface also allows the nodes/IoT devices status and alarm conditions to be displayed at a global level. The GIS control also facilitates navigation to a user defined faceplate.

Q: Has any asset management functionality been configured in the application?

As part of the assets tracking requirement for the Smart City project, a number of mobile generators were fitted with GPS IoT devices. This allowed the scada to display the current position of the assets on the GIS interface and also allowed alarm notification when an asset left its geo-fenced area. These alarm notifications have also been linked to configurable timers so if an asset stays outside its area for a user defined time, another alarm notification can be generated. In addition, the IoT will assist to enforce quality control as reservoir lids must be opened to get verification from the IoT device, which helps to ensure that samples are taken.

Q: Does the application include data archiving/historian capabilities with an historical data reporting system?

Currently, the system has only been configured for minimal reporting using Adroit native SQL logging functionality. Future integration with Adroit SCADA intelligentsia has been planned, which will allow for a richer reporting environment.

Maintenance, reliability and asset optimisation</b>

Q: Have any operational or production benchmarking tools been configured as part of the scada system?

N/A.

Q: What maintenance, reliability, asset optimisation or continuous improvement criteria were included in the user requirements specification for this project?

The Smart City project requires that the following functionality be included so as to ensure the reliability of the data being collected

• Device commutation failure (Last report received > 6 hours).

• Site maintenance mode – suppress alarms and exclude data from audit reports.

• Network quality.

• Sensor failure or out of service alarms.

Additionally the Adroit Alarm Management report suite has also been implemented to measure predefined system KPIs.

Mobile device support</b>

Q: Are you currently using tablets, mobile phones or other smart mobile devices to interact with the scada system? If so, for what purposes?

The system allows users to retrieve a limited dataset via their smart devices, depending on authentication and user rights.

Q: Do you allow users to interface with the scada system via their own personal smart devices? (BYOD)

Adroit Performance Anywhere utilises HTML 5 web services, which gives a user access to the data in the agent server via an easily configurable interface utilising predefined objects called widgets. This can be viewed in any web enabled device’s browser. Alternatively, web development is available via the HTML 5’s web service Software Development Kit (SDK).
