Explanation of operation
(1) When the measurement trigger (TRIG signal) is input from the external device, measurement is executed
once synchronized with the rising edge of the TRIG signal (OFF -> ON).
(2) The GATE signal is used to control the timing at which the external device captures measurement results.
Set the Gate ON delay (T3) and Gate ON time (T4) so that T3+T4<T5.
(3) When parallel output is set to "ON" as the data output destination, data is output for the number of times in
the expression set at "Calculation (data)" (maximum 32 times). When parallel output is OFF, data is not
output.
(4) When parallel output is set to "ON" as the judgment output destination, judgment is output for the number
of times in the expression set at "Calculation (judgment)" (maximum twice). When parallel output is OFF,
judgment is not output.
(5) The overall judgment is output. Overall judgment is NG if there is even one NG for the preset measurement
items and judgment results in the expression. In the case of level output, the ON/OFF status of the OR
signal does not change until the next output as shown in this example.
(6) When the timing for turning the ENABLE signal ON is set to "end of image input", a delay occurs until
output is started after the ENABLE signal turns ON as measurement is also executed after the ENABLE
signal turns ON. Do not input the next trigger until measurement is completed.

This is the delay time until the execution trigger DI8 signal is input after commands are set
to DI0 to DI7. Set a delay of at least 5 ms.
This time is "image input" + "measurement". This time can be changed to only "image
input" or "image input" + "measurement" + "display".
This time changes according to the ENABLE signal conditions."
