PLC Trigger Modes

When the job is in Single Shot trigger mode, the device runs one job on each trigger and decodes the barcode.

Toggle the trigger bit from 0 to 1 to perform a trigger. The job stops when the trigger is complete. Toggle the trigger bit to run the job again. Toggling the trigger bit from 0 to 1 runs the job one time.

Level Continuous initiates an image capture on a level trigger for objects in motion. This trigger mode is helpful for use cases that involve a conveyor belt. This mode consistently captures the image for the duration specified in the Active Job Timeout setting. When that duration expires, the job stops capturing the image.

To trigger the job for the first time, the trigger bit state should be toggled from 0 to 1. The job runs for the time specified in Active Job Timeout and stops. Toggle the trigger bit state from 0 to 1 to trigger the job for the first time. Toggle the trigger bit from 0 to 1 before the Active Job Timeout to manually stop the job. Toggle the trigger bit from 0 to 1 again to trigger the job again.

Burst mode initiates a series of image captures. This is helpful for use cases that require capturing a series of images based on a specified amount of trigger intervals and frequency.

In this mode, the first trigger event (toggling the trigger bit from 0 to 1), starts the burst sequence. Consecutive trigger events do not have any effect until the previous burst sequence is complete. The next trigger event (toggling the trigger bit from 0 to 1) starts the burst sequence again.

Periodic Single Shot mode initiates a single image capture after a specified time. This is helpful for debugging use cases.

Periodic Single shot maintains the triggering job periodically after a specified time period. Send the trigger again to stop the job in progress. While using PLC, the first trigger (toggling the trigger bit from 0 to 1) starts the job, and a second trigger event (toggling the trigger bit from 0 to 1) stops the job.

Continuous mode initiates a series of image captures rapidly. This mode is helpful for barcode scanning applications.

While in Continuous Mode, the PLC behavior is the same as in Periodic Single Shot mode.

Presentation mode presents an illuminated scan window when the sensor detects motion. Presentation mode is helpful for kiosk and retail point-of-sale applications.

The first trigger event (toggling the trigger bit from 0  to 1), starts Presentation mode. Send the second trigger event (toggling the trigger bit from 0 to 1) before scanning the barcode to cancel Presentation mode.
