4.4 Options for image acquisition and image processing
Image acquisition options
The image acquisition options of the reader were developed for a wide range of applications.
There are three different ways of controlling image acquisition and processing:
● Single trigger
● Auto-trigger (not available for SIMATIC MV420 SR-B)
● Scan (not available for SIMATIC MV420 SR-B)
Architecture of the internal processing sequence
The principle underlying the processing performed by the reader is a buffered processing
method in three steps:
● Image acquisition
● Decoding (reading)
● Outputting.
Between each processing step, the reader has a buffer and you can configure the size of the
buffer depending on the application.
This allows the ideal throughput to be achieved in every processing step resulting in the
maximum overall throughput for the reader and a flexible application.
