8.3.2 Outputting All Results (Output = All)
When the Handshake Function Is Set to “No”
Inspection data are output at intervals of set “Output signal guarantee time (Tp)”. STROBE signal turns on each
time outputting the data.
Receive data with the external device after rising edge of STROBE ON signal and before the next STROBE
signal turns on.
The following is an example of outputting data dividing into three times in Serial mode.
Tf: 400µs (fixed), Tp (1-1000ms): Data output guarantee time (default: 10 ms)
1. As the inspection ends, the first data (OUT signal) is output through I/O interface and turned on
STROBE signal and TACT signal.
Obtain the first result after more than 1 ms of wait time when STROBE signal turns on.
The time from when STROBE signal turns on till when the result output (OUT signal) is determined
varies according to the condition of the connected load or ambient temperature.
2. STROBE signal turns off after the time of Tp passes.
3. As the time of Tp passed from STROBE signal turns off, the second data is output and STROBE
signal and READY signal turn on(*).
Obtain the second result after more than 2 ms of wait time when STROBE signal turns on.
When synchronous output is operated in addition to I/O output, including data output to COM.0 port and
Ethernet port, and inspection image output, READY signal stays OFF until the operation is completed.
4. STROBE signal and TACT signal turn off after the time of Tp passes. Setting "Parallel I/O Output
Reset Condition" to "Reset" resets OUT signal at this timing.
5. I/O result output is complete after the time of "Tp+Tf" passes from TACT signal turns off.
You cannot output the next result while the time of "Tp+Tf" is passing in Parallel mode, and the device is in
the status of waiting for output.
