Libraries And Library Tabs; Verification Library - Siemens SIMATIC MV440 Operating Instructions Manual

9.2.6

Libraries and library tabs

The library concept available for SIMATIC MV400, version 5.0 and higher, allows you to
centrally configure central functions and settings. The central configuration is then repeatedly
used in programs and program steps.
For example, you can generate and configure user-defined character fonts in the character
font library. You can save up to five user-defined character fonts as library elements in the
character font library. The defined character fonts can be referenced and used in multiple
OCR steps of a given program or indeed in multiple programs.
The libraries are accessed by clicking on the
"Programs" task and selecting one of the available libraries:
9.2.6.1

Verification library

Note
Verification is only available for the SIMATIC MV440 reader.
The verification library is used to define verification settings and calibrate the reader for code
verification.
● You can run up to five calibrations and save them as library elements in the verification
library.
● You can then reference the verification library elements in the image acquisition of a
program. Referencing specifies the parameters for code verification in this program for
image acquisition and the decoder steps.
● The calibrated image acquisition may not always be enough for applications with highly
specific image acquisition requirements. In this case, you can overwrite the settings
specified by calibration in image acquisition.
Note
Verification results no longer comply with standard
In this case, the verification results will not comply with the standard; this is indicated by a
change in the verification type shown in the verification report.
