First Use Cases

You wish to monitor and control your remote units without deploying a full SCADA system, or you lack the appropriate internal resources ? For example, you are a small or medium size local authority managing educational, sports, cultural facilities, etc., or a water treatment station ? 

MUTUALIZE : using remote terminal units and TOPKAPI Webserv, a specialized service provider (ISP – Internet Solution Provider) will implement your supervision application, and host it.

  • You will receive fault alarms (TOPKAPI standby service).
  • You will monitor and control your facilities remotely.
  • You will analyze graphs and histories to check for proper operation using a standard web browser.
  • Hence, you will share the application’s cost (Computer, TOPKAPI license) and human resources (skills) among several users. Supervision of remotely managed equipment hence becomes economically accessible to applications of all sizes. Information processing will be entrusted to a specialist, as when you have your holiday photos printed.


The remote management + TOPKAPI + Webserv package is perfectly suited to multiple applications, such as remote maintenance of power generators, compressors, CMMS, flood monitoring and alarm, distributed energy production (hydro power micro station, wind generators, etc.…), and many other fields we cannot even imagine now.

In addition to mutualizing applications, the system also enables sharing information easily and economically (filtered according to requirements) among the various users of this information, both inside and outside the company.

As a large number of Webserv applications are now operating, a survey enabled us to collect the first feedback.

We remind that TOPKAPI’s Web server enables watching the supervision application, as well as reports and summaries using a standard browser, and also running controls when required. It comprises on the one hand a toolbox enabling full opening in respect of supervision (for developers wishing to implement specific applications), and on the other hand a component managing a Web site as a duplicate of TOPKAPI displays (for users who do not wish to become webmasters).

First, for most of the applications listed, it is the Web site generated by Webserv which is used, without any other customization than displaying a specific logo. The prime objective is to reproduce supervision in the Explorer for the stations connected ; customization, when needed, will be implemented at a later stage.

ELYO, who launched the ELYO Direct (www.elyo.fr) concept, relies on transparency, and enable their customers to monitor their facilities: boiler room view and equipment status, room temperature, boiler room incoming and outgoing temperature graphs, fault history. In addition to the instant installation of the standard site, the main benefit shown here is that after installation, no further action is required on the Web site except for administering access rights: when changes to the supervision application are made, the Web site is automatically updated.

Same situation at the greater Lille authority (CUDL), where Webserv provides agents with Intranet access to the supervision: after the initial installation, the web server is in the background, and only the SCADA application requires to be updated after process changes. One short day was required for the initial installation, including system settings.

We cannot mention here all the applications implemented, but they globally confirm the conclusions: the objective sought, i.e. simplicity and low implementing costs, was achieved. A few detail perfections are on the verge of being implemented.
