4.4.4 Image acquisition in program sequence mode
How it works
● You can enable the "Program sequence" option on the "Extras" tab in "Options".
With this option, you can evaluate several image acquisitions with different image settings for
each trigger, if, for example:
● Objects have a very large dynamic range in terms of contrast and reflectance, that cannot
be covered with one image acquisition setting.
● Codes or plain text must be searched for and read at different, defined positions.
● Several, possibly even different evaluations (for example with different code settings)
must be made per object.
● The number of definable regions of interest of an individual code setting/OCR setting is
not adequate.
