Condition fulfilled The camera image is evaluated, taking into account all
system parameters of the Free run mode:
– Start of image evaluation after cycle start
– Earliest start of output after cycle start
After output of the results of the check, camera images are
taken again until the conditions of the image-based trigger
are met again.
The system parameter “Start of image evaluation after cycle
start” influences the frame rate for analysis of the camera
images of the image-based trigger.
For quick reaction of the image-based trigger, put the
setting of this system parameter to “0”.
The process after a fulfilled trigger condition depends on the
system parameter “Image after fulfilled trigger condition”:
Setting
“Ongoing” As long as the condition of the image-based trigger is ful­
filled, the images are evaluated and the results output.
Setting
“Single image” After successful evaluation of a image and output of the
corresponding results, camera images are taken again. But
these images are evaluated only when the conditions of the
image-based trigger are
not fulfilled for at least 1 image.
Only then will just the first image that fulfills the conditions
of the trigger be evaluated.
The “Single image” setting ensures that the results for a part
are only output once, even if the part remains in front of the
Compact Vision System for an extended period and thus
again fulfills the conditions for the image-based trigger.
