If continuous image acquisition is set in the job, the image acquisition operation occurs as soon as the
previous image acquisition is complete. The
Camera Ready
signal is continuously activated during this time.
The Pass/Fail signal is switched at the end of image analysis but no earlier than the set output time. You can
recognize this time by a rising edge of the
Result valid
signal.
