I am working on a LabVIEW project for a probe station. The person who built the program left already, and I am learning about the structure of his project. In each of the sub VI category folder, I found some sub VI like XX_Properties.vi. However, it is linked to some variables. Also, If I choose hierarchy view, I am able to find the vi without any block diagram is actually associated with some other subVIs. I am confused. how can a VI without a block diagram associate with other VI? Please advise. Thank you very much!
Best,
Yaqi
