Telge Fastigheter builds for the future with web-based SCADA from Beijer Electronics

Telge Fastigheter owns and manages buildings totalling more than 500,000 square meters - divided into municipal and commercial properties around the county of Södertälje, Sweden.

At the end of 2018, Telge were looking to move their complex network of applications onto new HTML5-based SCADA software. HTML5 is the standard of today, providing the user with a faster, more adaptive experience and simplified coding. Having working with a SCADA system for many years, Telge knew they would need dedicated SCADA tools and expert support to help upgrade their network to web-based SCADA with minimum disruption.

Here Telge’s Systems Integration Consultant, Hadi Nasiri, explains how Beijer Electronics’ i4SCADA provided the perfect solution.


Tell us a bit about Telge Fastigheter and the challenges you were facing at the end of last year?

Hadi Nasiri (HN): We operate almost 100 buildings in the county of Södertälje - mainly education facilities such as schools and kindergartens, but also care homes, sports arenas and museums. We are responsible for the maintenance and development of all the technical systems.

We have worked with a SCADA system for many years, but the version we had was reaching end of life - and we needed to find a solution that would enable us to upgrade to HTML5-based SCADA software as painlessly as possible. For our building automation requirements, HTML5 is essential as it provides seamless, standardized user experience and is faster and more versatile than our previous software.

Towards the end of last year, we were starting to worry that we might have to make wholesale changes to our entire network in order to incorporate HTML5. But after some research, we found that Beijer could provide just what we needed in terms of local SCADA support and expertise.

What solution did Beijer Electronics provide?

HN: The best thing for me was that Beijer are SCADA experts. i4SCADA includes dedicated tools which Beijer has developed for building automation and management - including symbol libraries with functional objects and function blocks that fit the property business perfectly. Objects that we could use almost straight away.
Our network is extremely complex, with over 300 PLCs (programmable logic controllers) operating on more than a dozen brand platforms such as SAIA, Fidelix and Phoenix - as well as Beijer’s own hardware. In total we have over 86,000 tags controlling everything from heating and ventilation to alarms, pumps, fans and lighting systems across all our buildings.

Within a month, Beijer’s team had refined their dedicated tools for building management and automation within i4SCADA and since the turn of the year we have been working with it in a live environment.

I’ve been researching SCADA tools for over two years, and this was the first one I have seen that makes the HTML5 conversion process straightforward.

What was the added value Beijer Electronics delivered together with the technical solution?

HN: Definitely the close working partnership. In Sweden we have a unique attitude to automation and the way we are set up at Telge needs that local, hands-on support. 

On a personal level I was extremely happy and relieved when Beijer came on board. Before that I was trying to manage things alone. Now I have colleagues on my doorstep providing new insights and helping me see the project through a different pair of eyes.

We managed the initial two-month period as collaborators rather than a client/supplier model, learning from each other all the time.

The level of support is fantastic.

What made Telge choose Beijer Electronics?

HN: I looked at a number of alternatives, but realised quite quickly we had to stay with a SCADA solution. Converting to a completely new system would have taken 3-4 man-years and we simply don’t have the resources.

Because Beijer have been working with i4SCADA, they have the unique SCADA skillset and also deep knowledge of the technical side which allows me to focus on the visualization.

I don’t believe there was anyone else who could have fitted our brief more completely.

What does the future hold in your work with Beijer Electronics?

HN: While we started working with Beijer to solve a specific problem, these past months have been extremely useful in researching and discovering other Beijer solutions.

In particular we are looking at a Nexto Xpress Compact Controller that follows market standard programming via CODESYS - and there are other projects we are looking to collaborate on throughout 2019.

But I know that whatever we work on together, Beijer Electronics are a great fit for our requirements.
