The requirements

The reason for working to procure a new control system for the water supply plant was damage to the z'Hof pumping station controller and recorder caused by a power surge in 2009. The damage highlighted how difficult it was to obtain spare parts for the outdated controller. The aims of the new control system were to obtain a fully automated controller and to optimize reservoir management.

Solution provided by Endress+Hauser

Endress+Hauser (Switzerland) AG was awarded the contract for delivering and commissioning the new control system. The first step was to create a function description to serve as the basis for programming the application software. When selecting the system components, standard components with standardized interfaces were regarded as particularly important. This adds scalability, as it will make future system expansions easy to implement.
