All stationary optical SIMATIC MV440 readers are basic units under the terms of the "Text-Genius" and "Text-Genius Plus" licenses. The text recognition functionality is enabled by transferring the license key from the supplied USB flash drive to the 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.
