Description
The reception status of "Trigger enable" (D1000.0) is stored.
• On: Trigger is enabled.
• Off: Trigger is disabled
The reception status of "Trigger" (D1000.1) is stored.
• On: With trigger
• Off: Without trigger
The online status of a vision sensor is stored.
• On: Online
• Off: Offline
This signal is inverted (toggled) at the completion of an inspection of a vision sensor.
"Trigger" (D1000.1) is enabled while this signal is on.
By turning this signal off and on, an image capture is started.
"Trigger enable" (D1000.0) turns on to set a vision sensor to online while this signal is on.
By turning this signal off and on, "Trigger" (D1000.1) is turned on, and an image capture is started.

Precautions
• To check "Inspection Completed" (D1002.9), perform an interlock with "Trigger Ack" (D1002.1).
• This training does not include programming. When writing a program to a CPU module, write the pre-programmed project
"School_Vision.gx3".
