Trigger Function

The trigger function automatically starts and stops logging when predefined conditions are detected during monitoring.

• Operating condition

  • Works only when logging is enabled (Save Log File is checked)

• Trigger types

1. Frame detection: when a specific CAN frame is received
2. Key input: when a user-defined key is pressed

This allows efficient logging only at the required timing.
Configure triggers in the Trigger Window.

Trigger Mode​

Trigger operation patterns are as follows.

Trigger Mode	Condition	Operation
Free Run	-	Trigger function is not used. Logging starts/stops manually or by normal operation.
Triggered	Log Trigger / Key Trigger	Starts or stops logging once when a condition is detected. After stop-trigger detection, monitoring also stops.
ReTriggered	Log Trigger / Key Trigger	Repeats start/stop each time a condition is detected. Operates up to 64 times, then stops.

In ReTriggered mode, both start and stop triggers must be configured, and separate log files are created for each trigger.
