The following options are possible here:
• To use a specific, single beam for the evaluation, e.g., as trigger signal for a primary control.
• To group the complete measurement field into one switching area and thereby signal at the switching
output whether an object (at any position) is located in the measurement field.
• To configure up to eight switching areas for a reference check or height monitoring; in many cases,
this can make beam-data processing in the primary programmable logic control (PLC) unnecessary.
The switching conditions for the areas can be either AND or OR linked:
Areas may be sequential or overlapping. A maximum of 8 areas are available.
Example for the configuration of an OR or AND link for a light curtain with 32 beams
The following figure shows how the beam areas can be arranged directly next to one another or freely over

AND
1
If all beams mapped to the area are interrupted
0
If at least one beam is not interrupted in the selected area
OR
1
If at least one beam is interrupted in the selected area
0
If none of the beams mapped to the area are interrupted
The switching behavior or the conditions for switching a beam area on and off can be defined via
the interface (see chapter 9) or via the
Sensor Studio
configuration software (see chapter 11).
For an example configuration, see chapter 10.1.
