Description
3.8 Functional description
Optical Character Recognition (OCR)
● The high-performance character recognition algorithm is an optional add-on to code
reading, by which plain text is read by the camera.
● The reading of plain text can be combined with the reading of 1-D and 2-D codes.
● In order to filter out incorrectly labeled products, a comparison can also be made with a
predefined text.
● When reading plain text, a minimum quality can be specified.
● The high-performance character recognition can also be performed at very high clock
rates of up to 1 000 reads per minute (for example, with 10 characters per read).
● Customer-specific fonts can be saved on the reader (requires Text-Genius Plus license).
User management and access protection
The functions of the reader can be protected from unauthorized access and manipulation.
The access rights can be assigned to various personified users in the form of user roles.
Configuration via remote client
The configuration of the reader can be backed up and restored automatically using a
connected PC, for example when there is a shift change. This means the validation of your
production plant can be restored at the press of a button.
Track&Trace support
With comprehensive match options and remote commands, badly marked parts can be
reliably ejected with the aid of the integrated digital outputs. This also applies to applications
with high parts rates and speeds.
Scanner portal support
If the ultra-high resolution of the SIMATIC MV440 UR reader means that the large field of
view is not adequate for covering a transport path in a given application, multiple
SIMATIC MV400 readers can be configured as the portal if the large is not enough The
readers synchronize with each other. The master reader transfers the read result of the
portal to the higher-level controller.
Diagnostics functions
The reader has a wide range of diagnostics functions. If incorrect readings are made, the
diagnostics functions can be used to find reasons for the errors based on the recorded
pictures. This is, for example, necessary when problems occurred in the prior marking
process.
