That looks like a Feedback node.

What are you trying to do? You should be able to use a shift register to do the same thing.

Showing a picture of a tiny piece of LabVIEW code tells us very little, so we can provide very little help.  If you attached the entire VI, we could (a) explain how the Feedback Node works, and (b) suggest  how you might do the same thing the "old-fashioned way" (that I find much easier to understand) using a Shift Register.

Probably not the question , but, whats the initializer dot doing below the feedback node? Either it should be on the loop or it is the standard initializer terminal displayed as a star under the arrow. I cannot create the combination displayed.

If i just drop a feedback node from the pallette it has the initializer below.

If I drop the feedback node from the palette I can get the intializer that looks like either of these, but not one that looks like in the OP.

I wonder if that was some custom vi?

I know I've seen feedback nodes that looked like that.  It may go back to when they were first introduced.  The feature to move them out to the loop, and some other advancements came after they were first introduced.
