All stationary optical SIMATIC MV440 readers are basic units under the terms of the "Veri-Genius" license. The verification functionality is enabled by transferring the license key from the supplied USB flash drive to the optical MV440 reader by means of SIMATIC License Manager.

The functionality is available without a license in demo mode. The functions subject to licensing are fully available without performance restrictions in Demo mode. Only output of the results on the communication channels is disrupted. Users can therefore determine in Demo mode if the functions and performance fulfill their requirements.

Verification with MV440 verification systems is suitable for both inline and offline measurements. In both cases, the specification of the verification standard used must be observed to ensure a robust measurement result. This means that, for example, the lighting and alignment of the light source, camera and test object must be selected in accordance with the specifications of the respective standard.

If only one light source is used, the MV440 can control an external light source using the existing image-synchronized digital output, or the external light source can be operated continuously.

If more lighting directions are required, an external controller can be used to activated the desired lighting and to start each individual measurement by means of triggering. The result from the quality measurement or the relevant partial measurement is output directly by the MV440 after completion of the measurement. In the case of more than one measurement, it is the task of the external controller to combine the partial results into an overall result and to visualization this.

For a measurement with only one type of lighting, the measurement result can be visualized directly as a verification report in the form of an HTML page which can then be printed out.

If the test method requires calibration, the calibration card included in the scope of delivery can be used in most cases. In cases with extreme imaging requirements (e.g. with very small or very large codes), the task of calibration must be resolved application-specifically.
