# Checking the Application

Once you configured the job, the Online bit needs to have a value of TRUE in TIA Portal while the job is running on the In-Sight vision system.

To trigger the vision system, perform the following steps:

1. Enable the Trigger Enable bit by setting this bit to TRUE in the Modify value column, then click the Modify all selected values once and now icon. The Trigger Ready bit then needs to become TRUE, indicating that the camera is ready to be triggered.

2. Trigger the camera by giving it a rising edge on Trigger. Rising edge means that the bit is first set to TRUE (by setting it to TRUE in the Modify value column and clicking the Modify all selected values once and now icon), and then set back to FALSE.

   When the bit is set to TRUE, the Trigger Ack and Exposure Complete bits need to also change to TRUE, indicating that triggering is completed. The Acquisition ID value increments each time the PLC triggers the camera.

   Likewise, once the Trigger is set back to FALSE, the Trigger Ack bit also changes to FALSE again.

3. Check the job in the In-Sight. The newly-acquired image needs to appear.
