Simplified representation of the signal curves; these contain
no jitter, run times or system−related delay times.
The duration for the write operation of the outputs, and
thus the duration for an invalid output state, cannot be deter
mined when external outputs are used (I/O extension, device
as CPI module, EasyIP or CheckKon). If the external outputs
are deactivated by the system parameters, and if only internal
outputs are used, this duration is approx. 1 ms.
4.8.3 I/O features for evaluation mode fixed frame rate"
In the fixed frame rate" evaluation mode, the mode remains
activated as long as logical 1 is at the trigger signal" input
(status−controlled).
During this time, images are generated with a preset cycle
duration.
During evaluation, the output ready for operation"
shows a logical 0.
The start of image generation and the lighting begins with the
cycle start. Only the duration of the lighting can be influenced
via system parameters.
The evaluation and output of the results are temporally
decoupled from each other.
Images are generated at defined time intervals.
The time of the associated output, however, is indeter
minate and varies depending on the evaluation duration
of the current image, and possibly even the previous
images.
