Individual Trigger
When two cameras (Camera 0 and Camera 1) are connected in Serial mode:
Tf: 400µs (fixed), Tp (1-1000ms): Data output guarantee time (default: 10 ms)
1. To start capturing an image of the first camera (C0 above), make sure that REDY signal is ON and
then turn on STA signal (STA0 for the example above) for more than 1 ms.
2. PV500 turns off REDY signal and REN0 signal, and starts capturing an image.
3. To start capturing an image of the second camera (C1 above), make sure that REN signal for the
second camera (REN1 for the example above) is ON and then turn on STA signal for more than 1
ms.
When you employ individual trigger timeout, a timeout error occurs if the time from STA signal input of the
first camera to the input of the last camera exceeds the timeout. And then, inspection is terminated and
ERROR 0 signal is output.
4. PV500 turns off REN1 signal and starts capturing an image.
5. After all connecting cameras complete capturing all images, turn on REN signal (REN0 to 1 for the
example above) and execute checkers.
6. As the inspection ends, PV outputs a result through I/O interface and turns on TACT signal after the
period of "Tf".
Obtain a result after more than 1 ms of wait time when TACT signal turns on.
The time from when TACT signal turns on till when the result output (OUT signal) is determined varies
according to the condition of the connected load or ambient temperature.
7. TACT signal turns on for the time of "Tp", and then turns off for the time of "Tp + Tf".
You cannot output the next result while the signal is off and the device is in the status of waiting for output.
8. To start capturing an image of the first camera (C1 for the example) in the second inspection, make
sure that READY signal is ON and then turn on STA signal for more than 1 ms.
9. PV500 turns off REDY signal and REN1 signal, and starts capturing an image.
10. To start capturing an image of the second camera (C0 for the example), make sure that REN signal
for the second camera is ON and then turn on STA signal for more than 1 ms.
Afterwards, inspections are continued in the same way as above.
