Verification of code quality is an additional function subject to a license that can be activated on any SIMATIC MV440 by installing the "Veri-Genius license". The functionality is available without a license in demo mode.
The following typical types of fault can be detected by measuring the marking quality - the following pictures show examples of correct code and faults in the marking quality:
Correct code
Incorrect or non-uniform cell size in the marking
Incorrect or non-uniform cell size in the marking
Incorrect or non-uniform cell position in the marking
Incorrect overall geometry of the marking
Damaged surface of the marking or part
Very little or non-uniform contrast in the marking
Very little or non-uniform contrast in the marking
The following measuring procedures/standards are available for the purposes of inspection:
- AIM DPM-1-2006
- Siemens DPM
- ISO/IEC 15415
- AS9132 Rev. A (previously IAQG)
- ISO/IEC 15416 (previously ANSI X3.182-1990)
The measurement result is output as an overall result in 5 stages, which are named using letters or numbers:
|
Overall result as a digit |
Overall result as letters |
Overall result as text |
|---|---|---|

The components of a measurement result and calculation of the overall result are dependent on the test method used.
The overall result and the components of a measurement result can be output after a test, and are then available for further processing on an external system, e.g. for archiving or creating a test report.
