In single solutions for small machines without PLC connection, this approach results in savings due to no longer required external analysis units, less wiring as well as reduced space required in the control cabinet, among other things. In standard applications, the new light curtain can be connected centrally or distributed – without an analysis unit – to the safe PLC inputs. A light-curtain-specific additional programming, such as test or restart inhibit, is not necessary since this has already been integrated into the new sensors.
