Image evaluation starts with the triggering signal. During
image evaluation, the output “Ready for operation” signals a
logic 0.
The start of image creation and triggering of the lighting can
be established regarding the time of the triggering signal.
Set the following system parameters:
– Start of image evaluation after triggering
– Start of the lighting
– Duration of the lighting.
The results are provided at the outputs no earlier than the
time image evaluation is completed.
If the system parameter setting “Earliest start of output is
after triggering signal termination” = yes, output of results
can be delayed by extending the triggering signal. In this
case, the outputs can only be written when the signal at the
“Triggering signal” input has been ended. With this, a higher-
level controller (PLC) can signal its readiness to accept the
results of the parts inspection.
Also set output time and output duration via the following
system parameters:
– Earliest start of output after triggering
– Ignore triggering signal after ready for operation
The output “Ready for operation” is set to logic 1 only when
the results are valid at all outputs. The results can now be
processed, e.g. by a higher-level controller (PLC/IPC).
