Someone help me please understand what is this block? -Call Subvi

Hi all
During playback of a sample project a block stopped me. I could not understand what it is... once I click it (offline), it opens a Subvi, while runing the labview, it is clear that he will automatically call the Subvi. My Info is the one to call a Subvi VI main, you must use a static reference of Vi. Can someone help me understand what about this block?
I am attaching the picture of her and a container VI she also well... Simply open the block diagram of the file: "Caller.vi"... The Subvi associated with this block is fixed as well: "Config.."

I would like to know what is this block name, how it is related to the Subvi and how the Labview call it automatically. .. I really appriciate any suggestions.

Thanks in advance

Concerning
