Controlling Timing of Judgment with Triggers
For details of the trigger, refer to “Setting the Trigger Options” (Page 4-8).
External trigger
When the [Trigger Options] is set to [External], imaging and judgment are performed at the timing of
inputting the external trigger input.

(1) Positions the target and inputs external trigger. The shortest input time is 100 μs for ON, and 1.2 ms for
OFF.
(2) BUSY output function turns ON. Processing time differs depending on the settings.
(3) After the trigger delay time (Page 4-8) elapses, the target is imaged and the judgment process is
performed.
(4) After the judgment process is completed, it updates status output and the BUSY output function is
turned OFF. Confirms that the BUSY output is turned OFF, then imports the status output.
(5) If the external trigger is input while the BUSY is being output, the input is ignored and a trigger error
occurs. Trigger 3 is not judged. To output the trigger error, set the trigger error within the Output
Assignment (Page 4-60) under Settings Navigator to [ON].
y The ON status of each output is as follows.
When Output Settings (Page 6-27) are [N.O.]
: Status with NPN or PNP open collector ON.
When Output Settings (Page 6-27) are [N.C.] : Status with NPN or PNP open collector OFF.
y The ON status of each input indicates 0 V line is shorted when the Polarity (Page 6-28) is NPN, and
indicates that voltage is applied within the 0 V line when the Polarity is PNP.
y The edge trigger for activating timing or in deactivating timing can be set for the external trigger input.
“Input Settings” (Page 6-26)
y The trigger error output function turns OFF when the next trigger is activated, when the error is cleared,
when the program is switched, or when the system moves to the settings screen.
y When the output mode (Page 6-27) of status output is set to [Latching]. When the output mode is set to
[One-Shot], refer to “Changing the timing of the status output” (Page 7-6).
