Default Description
Disabled You specify how many codes are read per image.
Disabled: Only one code is searched for in the
•
ROI. If multiple codes exist in the ROI, only one
code is read.
Enabled: The specified number of codes is
•
searched for. If more than the specified number
of codes are visible in the ROI, the excess codes
are ignored. The multicode function requires the
standard decoder; not available with ID Genius.
☑
Enabled:
•
If the same number of codes per code type is not
read in the image in processing mode as when
the program is saved:
The string defined in "Program" > "Result" for
"Read error" is output as result and the output
signal "N_OK" is set.
Note
Using multiple code types
–
–
To precisely specify the number of codes to be
read per code type for multiple code types, con-
figure your own "Read code" step with the corre-
sponding number for each code type.
Disabled:
•
If the same number of codes per code type is not
read in the image in processing mode when the
program is saved, no read error is output.
This is the case:
–
–
If the data matrix code type and at least one
barcode type is present in the decoding or-
der, the specified number of data matrix
codes and barcodes is searched for when the
program is saved.
If more than the specified number of codes is
found in total, an "N_OK" event is generated.
If the save operation was successful, the pro-
gram will search in processing mode for the
exact number of codes found for each code
type that it saved.
When fewer codes are actually visible.
When the cycle time or decoding time limit
was reached before all codes could be de-
coded.
