On conveyorbelts that operate over significant distances a traditional installation of safety switches with parallel wiring may be quite expensive and diagnostically inaccurate. A solution to this situation can be the application of a bus-system.
Sitec switches are optionally provided with an interface that is compatible with Caro Gavazzi Dupline® Fieldbus or Dupline® Safe components.
In this way signals can efficiently be transferred over longer distances. The control centre can read and show each single signal. Those signals can also be controlled and managed by an SPS or a PC.
