To not use PROFINET, deactivate
PROFINET.
In the default configuration of the

during startup whether the device is
in a PROFINET environment and acti‐
vates PROFINET automatically.

Description
Read Diagn
(read diag‐
nosis)
Percentage evaluation: the device records images. The device uses the
current settings of the read properties to decode them. With the 0 to
100% bar graph, the device shows the read rate of the last 10% (90%
to 100%).
The bar graph display is activated in standard read mode.
Autofocus
The device adjusts to the working distance. The device permanently
stores this working distance.
