If the “Trigger signal” input still shows logic 1 after expiry of
the set duration, the next evaluation is started.
The results are only written to the outputs when the device is
finished with the image evaluation and specification of the
“Earliest start of output” system parameter has expired.
The outputs remain valid until the specification of the system
parameter “Earliest start of output after cycle start” of the
next cycle has expired.
Outputs to outputs can be invalid even earlier, depending on
the setting of the following system parameters:
– Reset outputs at outputs after “Ignore triggering
signal”
– Reset outputs at outputs during analysis.
If the “Trigger signal” input is reset to logic 0, the free run is
ended. After the momentary image evaluation is completed
(incl. “Earliest start of output after cycle start”), the “Ready
for operation” output goes back to logic 1.
The outputs of the output module of the I/O extension O0 to
O3, like the internal outputs, are configured via the system
parameters, that is, they are set or reset together with the
internal outputs.
