Our business is in constant evolution, particularly due to New Information and Communication Technologies (NICT) and new modes of consumption. Supervision solutions must undergo deep mutation to adapt to the needs of Industry 4.0, IIoT*, Big Data, Smart Grid or Data Intelligence, ...

Welcome to the Smart World. Everything is ‘smartized’: Smart Buildings, Smart Water, Smart Industry, etc. Today, all-smart is becoming reality, materializing in the field.

How does AREAL respond to these new requirements?

This new newsletter answers this question, through concrete cases of use of our TOPKAPI supervision solutions.

For us, being smart first means meeting openness, interoperability requirements (with third party applications or hardware), and access to information in mobility, cybersecurity and deployment flexibility/ease. Those are our current and future development focuses.

We must offer innovative solutions meeting all these needs for new projects while preserving the investments of our existing clients who trust us, and offer the ability to upgrade to the Smart World...

We wish you a pleasant read through.

Version 6.0 – HTML5 Web server

Announced in pre-marketing during the Pollutec and IBS 2016 fairs (refer to Lettre TOPKAPI n.24), TOPKAPI version 6.0 including its new HTML5 Web Server module is our current response to the Smart World.

Since it was launched, it has made its way, with a very warm welcome. Several hundred licenses are currently operating in version 6.0, with the full benefit of the many updates offered: for more information refer to and It should be noted that this version will be available in foreign languages by the end of the year.

We wished to deploy this version gradually, by means of a controlled  process. All our clients under annual maintenance contract can now benefit from it in French language, and very soon in foreign languages: please call your usual AREAL contacts for the terms of supply and migration.

But how does version 6.0 actually meet Smart World requirements? The following themes allow this question to be answered.


Security related with the exchange of information between components is one of the first stakes of the Smart World.

Over many years, AREAL has been highly involved and concerned by Cybersecurity :


  • Participation in the workgroup directed by ANSSI* since 2014
  • Version 6.0 integrates the recommendations of this workgroup
  • Security aware software development process
  • Permanent technological watch for the application of security patches when necessary
This concretely translates into the following TOPKAPI version 6.0 :
  • Web client /server connections certified and encrypted when using the Webserv2 module
  • Secured user account checking
  • Use of secured communications using TLS (formerly SSL), including checking the identity of clients and servers by certificates for exchanging data with third party solutions/hardware
  • Authenticity and integrity of the TOPKAPI software components upon their installation and update
  • Integrity and confidentiality of the configuration via the user account management policy
  • Advanced and fine management of user categories and roles
  • Full traceability of operator actions in operation

An architecture based on the new Webserv2 component (HTML5 web server) for consultation, particularly from the ‘outside’ meets current and future stakes in terms of Cybersecurity, while not complexifying the client/server communication architectures.

Within the framework of the public service provision markets for the management of the sanitizing network for local authorities, such as Val d'Europe Agglomération or the Seine et Eure Authorities Community, the SAUR company  validated this innovating and secured architecture. More particularly, it offers local authorities a ‘contractual’ access via TOPKAPI to the facilities operation information simply (viewing information via a Web browser), securely and integrating perfectly into the SAUR’s computer infrastructure. The previous experiments based on TSE/RDP clients were inconclusive, whether in terms of deployment simplicity, performance and security.

For more detail on TOPKAPI and cybersecurity, you may ask for the white book ‘Military programming law & Cybersecurity’ by AREAL.

In our hyperconnected environment, we all wish free access to information using our mobile devices.

A pioneer in the field for many years with its Web client, TOPKAPI modernises the subject with its Webserv2 component (, which leverages the latest HTML5 Web technologies to make information available and control its facilities on all types of media: PCs, laptop PCs, smartphones, and tablets. In addition to numerous functional enhancements offered by this new module, we have taken into consideration the management of touch devices very specifically.

For fast access to the right information at the right place, the use of QR code/DataMatrix or NFC tags ensures instant opening of the right page in the application, while preventing tedious browsing: a simple and effective solution to meet the geotargeted supervision need. Security and authentication are obviously taken into consideration. For more information, meet us at the IBS and Pollutec 2018 exhibitions for a ‘live’ demonstration.             


Within the framework of an innovative pilot project linked with Industry 4.0 on BMS, and more particularly utilities management, a global leader in the cosmetic industry (which has wished to remain anonymous) chose TOPKAPI and its Webserv2 component for the needs of its plant located in the Poitou region in France. Its easy setting, openness, the consideration of cybersecurity and fast deployment, particularly in mobile access with QR code flashing, were key points in its selection.

This application collects data from utilities (consumption of water, gas, steam, etc.) and the information system; data necessary for the Maintenance and New works department to check that the production environment is optimum. It uses typical supervision functions, while also offering access to maintenance sheets, manual data entry, real time dashboard viewing and use of integrated data analysis and extraction tools. Deployments to other plants in the group are also being studied.




IIoT (Industrial Internet of Things) facilitates the instrumentation of facilities at a lesser cost, by offering some deployment flexibility (energy independent communicating sensor or actuator). It calls upon technologies such as Sigfox, LoRa, MQTT, Webservices, ... which are increasingly generalizing in the field.

In the field of supervision, the stake is to combine data acquired in a traditional manner with IIoT data. How does TOPKAPI respond to this subject today?


We can say that TOPKAPI is IIoT compatible, but the lack of standard and disparity of the offers present in the market require individual handling of each request, unlike with standardized communication protocols. To respond effectively and in a financially reasonable way, we designed a protocol driver programmable in JavaScript integrating ready-to-use libraries.

We can illustrate this with the example of the Sigfox network: the communication infrastructure is proprietary and the (time-stamped) data is made available via a portal called a ‘backend’, which TOPKAPI has to interface with. The data organisation is specific to each manufacturer: it requires adapting the data exchange protocol to each type of device. No standard Sigfox driver can be proposed. The use of a ‘scriptable’ protocol is a simple and effective solution to this issue.

For example we have implemented this type of development upon request from the Régie des Eaux Gessiennes: TOPKAPI now acquires data from Ijinus Sigfox devices (water treatment network instrumentation here) and Connit Sigfox (for telemetering).

Another interfacing over Sigfox network is also being studied for IDEX, who has recently chosen TOPKAPI for its nationwide supervision solution for its building operation business. The IIoT equipment is supplied by ATIM and ENLESS (temperature sensors, multi-energy meters, etc.) with 10,000 connected objects to be linked.

For more details on TOPKAPI and IIoT, as well as the different technologies mentioned above, ask for our white paper ‘IIoT & TOPKAPI’ by AREAL.



A connected environment requires interfacing TOPKAPI with miscellaneous and various hardware, as well as with third party software applications. Supervision must increasingly blend into the company’s Information System. 

The ‘IIoT’ section (see above) and ‘New communication protocols’ section (hereafter) demonstrate the constant efforts made by AREAL to improve interoperability with equipment.

For duplex data exchange with third party software applications, we offer different possibilities: refer to

The last component developed by our services is a data server in the form of a Webservice. It allows TOPKAPI to expose its data to third party applications in read/write (real time and sampled data).
The Webservice provided is of the API REST type, in the Json format. Cybersecurity and access rights were taken into consideration, as the medium used is https and authentication of the third party login into TOPKAPI inherits the rights specific to TOPKAPI.


We also offer bespoke developments. We have performed such work within the CPE (Contrat de Performance Energétique, Energy performance contract) covering 140 schools, awarded to the ENGIE COFELY – ARTELIA Building & Industry pool in 2016 by the City of Paris. This contract aims at reducing energy consumption in schools by a least 30%.

For the activities we are concerned with, it relies on:
-    The implementation of a smart facilities monitoring and remote control system aiming at energy performance guaranteeing optimized management of consumptions
-    Use of innovative object technologies at the service of energy transition to make buildings smarter and lower their energy consumption

A total 15,000 wireless connected objects were deployed. These objects are managed by ENGIE COFELY’s VERTUOZ solution ( TOPKAPI ensures centralised management of local regulators over a BACnet network.

The 2 solutions had to be interfaced in order to:

  • Use the values of the sensors (temperatures, presence, CO2) and the information per zone  
  • Manage the operating alerts
  • Implement duplex exchanges with VERTUOZ of information linked with the schedules of use and set point temperatures
  • Manage archiving, monitoring and transfer of data to the dedicated servers

To interface the 2 solutions, we have developed – together with ENGIE COFELY – a specific secured Webservice  supported by REST/Json APIs.

By allowing communication with BACnet regulators and connected objects, TOPKAPI provides the schools’ supervisor with an overall view of the installed base and key indicators, allowing optimizing energy consumption and improving user comfort.


Many of our clients prefer direct and integrated communication (self-setting, structured objects, etc.) between TOPKAPI and the professional equipment they wish to use. Therefore we continue investing in this field and new devices are being added to the current, already rich, ‘catalogue’ (refer to

  • S4W controllers by Sofrel: the secured Lacbus version is now available, in version 6.0 only. This allows TOPKAPI to be integrated to Sofrel’s cyber ecosystem.
  • PlicsMobile Data logger by VEGA: these devices are now supported in SMS type acquisition.
  • Phocus3 and Enigma by Primayer: these devices dedicated to pre-localisation of leaks for drinking water networks are accessible in TOPKAPI via a protocol of the Webservice type: data hosted on a Primayer or client portal are used as any other type of data... The ‘sound’ files are also transferred to the TOPKAPI station.
  • Flowmeters of the MAG8000 type by Siemens via the FileFTP protocol.
  • Cello (data logger) / Regulo (pressure checking in water networks) by Technolog: dedicated direct protocol without communication front end.
  • Ortomat by Vonroll Hydro: water leak analysis and detection. Equipment managed by the FileFTP protocol.
  • Ijinus sensors via Sigfox platform: available with the Ijinus protocol.
  • Connit hardware via Sigfox platform: water remote metering and management.
  • Nivulink Micro and NivuFlow Mobile hardware via the FileFTP protocol
