The image evaluation starts with the trigger signal. During
image evaluation, the output ready for operation" signalises
a logical 0.
The start of image generation and lighting control can be
defined with respect to the time of the trigger signal.
·
For this, set the following system parameters:
Start image evaluation after trigger
Start lighting
Duration of lighting
The results are output at the outputs after the image
evaluation is finished, at the earliest.
The output time can be delayed by prolonging the trigger
signal. The outputs, in this case, are only written when the
signal at the input trigger signal" has been taken back. This
way, the higher−ordered controller (PLC) can signalise its
readiness to accept the results of the workpiece inspection.
·
Also, set the output time and output duration via the
following system parameters:
Earliest start of output after trigger
Ignore trigger signal after ready for operation
The output ready for operation" is only set to logical 1 when
the results at all outputs are valid. The results can now be
processed by a higher−ordered controller (PLC/IPC) for
example.
