4.10.1 Defining beam area
To read out the beam states block-wise with a 16-bit or 32-bit telegram, the individual beams can be
mapped to up to 32 areas independent of the maximum beam number. The individual beam information
of grouped beams is linked to a logical bit, i.e., each area is represented as 1 bit.
The number of beams in an area can be freely defined. However, the beams must be adjacent to one
another. The start beam and the end beam are to be defined as well as the conditions for switching of the
area.
4.10.2 Autosplitting
The beams of the device are automatically divided into the selected number of areas of the same size. The
states of the areas generated in this way can be read out in the process data by means of the
“Area Out - HiWord” and “Area Out - LoWord” parameters.
Procedure:
• Select logic combination of the beams within the areas (logical AND / logical OR)
• Define the number of desired areas (e.g., 16 or 32)
4.10.3 Mapping beam area to switching output
If grouping individual beams or if creating a block, the beam state of any number of adjacent beams (area)
can be signaled at a switching output.
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 32 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 32 areas are available.
NOTICE
Hold function for beam areas!
The hold function (see chapter 4.5) also applies for the block evaluation of beam areas.
The autosplitting configuration can be defined via the respective fieldbus interface (see chapter 9
et seq.) or via the
Sensor Studio
configuration software (see chapter 12).

The switching behavior or the conditions for switching a beam area on and off can be defined via
the respective fieldbus interface (see chapter 9 et seq.) or via the
