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.
4.8.2 I/O features for evaluation mode free run"
In the free run" evaluation mode, the free run mode remains
activated as long as logical 1 is at the trigger signal" input
(status−controlled). During this time, images are generated
and evaluated cyclically.
Sequence The image evaluation starts with the beginning of the cycle.
During image evaluation, the output ready for operation"
signalises a logical 0.
The start of image generation and the control of the lighting
can be defined with respect to the time of the beginning of
the cycle.
·
For this, set the following system parameters:
Start image evaluation after beginning of cycle
Start lighting
Duration of lighting
The results are output at the outputs after the image evalu
ation is finished, at the earliest.
·
Set the output time via the following system parameters:
Earliest start of output after beginning of cycle
Ignore trigger signal after ready for operation
