Cloud-Based Asset Management of Decentralized Systems

Data relating to error reports and monitoring is sent to the cloud to enable better monitoring of both the Saarlouis central energy supply and a well system. The program’s success has led the German city to consider expanding the cloud projects.
Between 1824 and 1829, when the Prussians expanded parts of the old fortifications from the Thirty Years’ War into command posts and housing for soldiers, horses and provisions, they created a bomb-proof project. To this day, the historical ramparts, the so-called casemates, form an important part of the Saarlouis cityscape. However, their use has changed fundamentally: Restaurants have been set up under the arches and attract visitors from near and far to the longest buffet in the Saarland. But though the casemates are easy to reach from the center, they are far from the telecommunications network. Data connections are therefore difficult to establish, even though they are important for regulating the local district heating used by ten cafes and restaurants. The energy control center, with two pumps for providing hot water to the restaurants, is installed at the head of the casemates. If they fail, guests will get cold feet, since a great deal of time can pass before the damage is reported, a city employee gets to the site and the problem is solved.

Easy Cloud Use without Programming Knowledge

Therefore, the city administrators in Saarlouis had to act. “System availability is important to me“, says Bodo Jenal, building automation project manager in the Saarlouis building department. Because tearing up the street was not cost-effective, a mobile solution was selected. Together with specialists from the building technology company, BVT Bellmann, from the neighboring town of Dillingen, city administrators developed a cloud-based solution for fault reports and data collection. A WAGO PFC200 Controller with a mobile radio module forms the project's core.

“We are beginning with fault reports for now,” says Jenal. Fabian Klauck, electronics project manager at BVT Bellmann, believes that the combination of the PFC200 with the WAGO Cloud will ease them into digital asset management. “The dashboard enables convenient and intuitive operation of all windows. However, the biggest advantage is that no programming knowledge is necessary to get the data to the cloud,” says Klauck.

Many Additional Monitoring Functions

Jenal sees another advantage in the demand-driven scalability of the cloud system. “In the future, we’ll undoubtedly think of several different tasks we can handle using this cloud-based technology.” For example, additional monitoring functions are available that would be quite useful for drinking water sanitation. Early warnings are especially critical for preventing a Legionella outbreak.

Not much was required from the in Saarlouis in order to be able to take advantage of the benefits of the WAGO Cloud. “We no longer need to worry about it from an administrative and safety point of view,” says Jenal. “We retrieve the values from the cloud and visualize them as we want; WAGO handles everything else in the background.”
