Example
A storage rack with screws is monitored using a cascading Object100 light curtain. A master controller controls
whether the correct parts are picked. A box has a width of 20 cm (X-axis) and a height of 15 cm (Y-axis). The
rack measures 2.2m in width and 1.5 m in height. Therefore it can store 11 trays per level over 10 levels.
The configuration of the ObjectC
Table 44: CAN commands for the configuration of the example above
Deactivation of periodic mode
Activation of event mode
Elements per zone in X-axis
(20 cm = 8 beams, pitch 25 mm)
Elements per zone in Y-axis
(15 cm = 6 beams, pitch 25 mm)
Separation of Y-axis
(1.5 m = 60 beams, pitch 25 mm)
With this configuration, the ObjectC°100 sends a command at every interruption of the light curtain.

Figure 6: The cascading light curtain nearest to the controller is
determined as the Y-axis. Its length has to be configured with
parameter 81 [51 Hex].
