• High wiring costs due to a large number of pneumatic sliders and flaps in a confined space
• Optimization of the control cabinet space
• Longer search times in case of an error due to low diagnostics

Aregger engineering ag is a medium-sized electrical engineering company based in Sursee, Switzerland, providing services in the field of control engineering. Its core business is complex control tasks, mainly in the dairy and compound feed industry.
The high wiring effort was met by using the ET 200AL system, which as a small and light distributed periphery system in block design with IP65/67 can be mounted directly next to the relevant elements, thus simplifying wiring and mounting. The ET 200AL can be connected directly to the ET 200SP IO-system, which is used in the control cabinet. Due to the small footprint of the ET 200SP system, a lot of space could be saved in the cabinet. Additionally the availability could be improved thanks to the detailed diagnostics of the ET 200SP, ET 200AL and the SINAMICS frequency converters.
