Trigger problem of data acquisition

[Comp1ex]

This question annoys me. This is my description of the problem.

I have a Advantech data acquisition card pci1712. I have successfully written the trigger acquisition program I want.However, this can only effectively occur once for a single trigger acquisition.I can only run the VI of the acquisition program first, and then manually click the VI that triggers the square wave. In this way, the VI of the acquisition program can effectively capture the trigger signal, and then start the acquisition.

I want to make this process continuous. I tried to add their two vis to two while loops. But it didn't work.

Please help me.

here is my daq vi and trigger source vi

my trigger daq vimy trigger source TTL generator
