Product description
The system is operated in combination with an MSC800 Controller. The reading results are
output at the data interfaces via the controller. External sensors deliver information via the
reading pulse, the object distance and the conveyor speed.
3.4.1 Reading configuration
The ICD890 Camera detects 1-D/2-D codes line by line with the help of a CCD line. The
lines are written successively and with a high frequency into an image storage. Continuous
feeding of the object on the conveyor system produces a two-dimensional image of the
object.
Note The ICR890 System cannot recognize codes on stationary objects.
A moving 1-D/2-D code on an object is displayed as a grey level matrix in the image storage.
Contrast jumps are analyzed in order to scan the codes. The threshold value can be adapted
to the ambient conditions.
For more rapid analysis, the analysis area can be restricted to across the direction of
transport (code position).
The SOPAS-ET Configuration Software can, among other things, be used to configure
features, such as the code position and the symbol contrast:
