External Channel Selection via Digital Inputs or Toggle Switch
Light curtains with digital inputs or digital inputs/outputs (I/Os) offer the possibility of dynamically selecting
a channel via an external device. At variants with toggle switch, the dynamic assignment can be done by
manually toggling the switch. For example, an output can be configured in such a way that a pulse is output
each time the currently selected channel detects an object.
