Parameter Declaration Data type Address
Default Description
X position of the center point of the code
relative to the center of the image. Normal-
ized to the full resolution for the current
Y position of the center point of the code
relative to the center of the image. Normal-
ized to the full resolution for the current
Rotation angle of the code center point
(angle between the axis of the optical read-
er and the surface of the code field)
Symbol contrast as class
(value valid if ≠ ' ')
Print growth as class
(value valid ≠ ' ')
Axial non-uniformity as class
(value valid if not equal to ' ')
(value valid, if ≠ ' ')
Note:
If a "ReadErr" occurs, the old result data is
retained because no new data is available.
Overall quality as class
(value valid, if ≠ ' ')
Symbol contrast as absolute value
(value valid, if ≠ "-1.0e+0")
Print growth as absolute value
(value valid, if ≠ "-1.0e+0")
Axial non-uniformity as absolute value
(value valid, if ≠ "-1.0e+0")
Unused error correction
(value valid, if ≠ "-1.0e+0")
