Use in PROFINET
1
After starting, the device loads the last permanently stored internal parameter set
to its working memory.
2
The device then searches for a valid parameter set in the optional external mem‐
ory card slot. If there is a positive search result, the device overwrites the existing
parameter set in its working memory with this external parameter set.
3
If the PROFINET controller sends a parameter set via the PROFINET with central
configuration of the bus users, the device again overwrites the parameter set in
its working memory. These changes are lost again when the device is switched off.
The PROFINET controller must then again send the most recently valid parameter
values each time the device is restarted (supply voltage is switched on).

Coordinate system
The X- and Y-coordinates provided by the device refer to the zero point of a coordinate
system in the field of view of the device. If the X- and Y-values are output in millimeters,
the zero point of the coordinate system is located in the center of the field of view.

Figure 17: Coordinate system in the field of view of the device
If individual 2D codes are used, the device determines the shift of the code center
point to the zero point of the coordinate system.
When using multicode labels, the device determines the shift of the center point of the
multicode label relative to the zero point of the coordinate system.
