Functionality
The user saves the current parameter set to the permanent parameter memory of the
device using the Permanent option. In addition, the user manually saves the parameter
set as a project file (sopas file with configuration data) on the computer.
The device then automatically also saves the parameter set to an external, permanent
parameter memory.
The parameter set is saved to the MicroSD memory card.
At each restart after being switched on, the device automatically loads the compatible
parameter set from the external storage medium into its working memory and into its
internal, permanent parameter memory. This enables a device, e.g. in the event of a
device failure, to be quickly exchanged with a replacement device of the same type.
The device replacement is achieved without any loss of configuration data, and without
having to connect the computer to the SOPAS ET configuration software.
7.3 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 22: 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.
If multicode labels are used, the device determines the shift of the center point of the
multicode label to the zero point of the coordinate system.
