8.3.1 Typical Operations in Inspections

Common Trigger
In serial processing mode
Tf: 400µs (fixed), Tp (1-1000ms): Data output guarantee time (default: 10 ms)
1. Make sure that REDY signal is ON and then turn on STA0 signal for more than 1 ms.
2. PV500 turns off REDY signal and REN0 signal, and starts capturing an image.
The OFF time of REDY signal is called "inspection time" up to No.4.
The delay time mentioned on the right may occur
from the input of STA signal until the start of image
capture (REN signal is OFF) when displaying a live
image.
3. After image capturing is completed, PV turns on REN0 signal and executes checkers.
4. As the inspection ends, a result is output through I/O interface and TACT signal and REDY signal
are turned on after the period of "Tf".
When PLC communication or synchronous output (general output and image output) is operated,
REDY signal turns on after the operation is complete.
After REDY signal turns ON, the device can receive the next STA signal.
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.
5. TACT signal is turned on for the time of "Tp", and then turned off for the time of "Tp + Tf".
While the signal is off, result of the next inspection is not output.
