Parallel I/O Reset Condition
This item is to select reset timing of OUT signal when outputting inspection result through Parallel I/O connector
and Parallel I/O terminal.
Hold (default): To hold until outputting the next result.
When the first and second inspections turn on OUT0 signal, the signal keeps ON until the third
output of inspection result without turning off.
Reset: All OUT signals turn off when TACT signal turns off.
Refer to Chapter 8.3 "Timing Chart" (page 378) for details.
Inspecting with Internal Trigger
(Continuous Inspection)
This method executes inspections repeatedly before receiving START signal from the external device. This is
"Continuous Inspection" and helpful to inspect continuously due to a long object. A signal input from the
external device can stop repeating inspections.

An inspection is complete before outputting images, and then PV500 outputs
images when it can. When the interval of START signal input (the period between
inspection start and the next inspection start) is short, and Image Output is not
completed after several inspections, PV500 completes Image Output by delaying
the next inspection start.
An inspection is complete before outputting images, and then PV500 outputs
images when it can. When the interval of START signal input (the period between
inspection start and the next inspection start) is short, and image output is not
completed, PV500 internally stores images up to a certain number as images to be
output. If the number of images exceeds the storable capacity, new images cannot be
stored in PV500 until enough space for storing is created by outputting the image that
have been stored in PV sequentially. Inspections are executed on images that cannot
be stored, however, image output is not executed.
Executes an inspection by START signal input.
After PV500 starts up, inputting START signal at the start of the first
inspection executes inspections repeatedly.
After PV500 starts up, inspection is repeatedly executed soon. START
signal input is not necessary.
