Change of location: Out of the casemates, to the green belt of Saarlouis – the city park outside the old fortification walls. Here a WAGO PFC200 Controller with an integrated mobile radio module is used to collect level data from a freshwater well from the 1950s. The city administration uses the well to replenish a pond and for general irrigation – in other words, watering flowers. “When drawing off the water, we need to make sure that we are not overtaxing the well's capacity and endangering the aquifer,” explains Jenal.
Thanks to the cloud solution, the people in charge have everything reliably under control. The fill-level data can be securely retrieved from anywhere. The data can also be used to create trend analyses, which allow for better predicting dry periods, and thus better irrigation planning.
Fabian Klauck from BVT Bellmann envisions further applications for the PFC200 and WAGO Cloud: For instance, the controller could be used to control entire ventilation systems and send data that is relevant for building technology to the cloud for further processing. “With the PFC200, the casemates and city park now have a powerful PLC, which can also be freely programmed – that opens up many possibilities,” says Klauck.
