1.1 Timing Chart
Typical Operations in Inspections
Common Trigger
In serial processing mode
Tf: 400µs (fixed), Tp (1-1000ms): Data output guarantee time (default: 10 ms)
* Out signal turns off this timing when setting "Parallel I/O Output Reset Condition"
to “Reset”.
1. Make sure that REDY signal is ON and then turn on STRT signal for more than 1 ms.
2. PV-T30 turns off REDY signal and REND 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 STRT signal until the start of image capture
(REND signal is OFF) when displaying a live image.
0.3-Mega Compact Camera:Max. 12 msec + Shutter speed
3. After image capturing is completed, PV turns on REND 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 executing synchronous output (data output to COM port and Ethernet port or image output) as well as I/O
output, REDY signal stays OFF until these outputs complete.
After REDY signal turns ON, the device can receive the next STRT 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.
6. Out signal keeps on status until the next output (Hold), or turns off when TACT signal turns off
(Reset).
Follow the procedure described below to select “Hold” or “Reset”.
