Extended settings (group 5)
Process data settings (group 6)
The process data extension permits the serial output of the individual pieces of beam data. Each individual
beam can be processed and transferred as a bit independent of measurement field length, resolution and
beam mode (beginning with firmware version v2.10).

The filter depth indicates the necessary number of
consistent beam states before the evaluation of the
measurement values. The filter depth corresponds
to the number of passes with interrupted beam so
that the result leads to switching.

The process data settings describe the cyclically transmitted process data.
NOTICE
A maximum of 256 beams can be processed as a bit!
The IO-Link specification only permits 32 bytes as process data; i.e., up to 256 beams can each be
processed and transmitted as a bit.
Through the limitation of the process data length, the beams, depending on the resolution, can only
be processed and transmitted up to a certain measurement field length as a bit.
