For Loop Symbol what is it?

[SkyeS]

Can someone please help me identify what that triangle symbol is on the for loop that the 1 is wired to? I haven't seen this symbol before and I'm not sure what it does. Trying to figure out what its called so I can do more research.

Well, a Black-on-black picture of a block diagram is pretty difficult to see and doesn't much help me answer your question.  Why not attach your VI, the actual file with an extension of .vi?  No pictures, just LabVIEW!!!

Hello, The symbol which you mentioned is "feed back nodes initial value is moved out of the loop"then you will get that symbol.

Hi SkyeS,

while attaching your VI you might open the context help in LabVIEW and move the mouse over all the items in your block diagram.

And please revert to use the default white backgorund in the block diagram!

That is the initialization terminal for the feedback node, to which you wire the value you want the feedback node to provide on the first iteration of the FOR loop.  When you place a feedback node on the block diagram, the initializer terminal is usually part of the node icon, but the right-click context menu offers the item: Move Initializer One Loop Out, which moves this terminal to the left side of the loop structure.

Thank you for answering this. I was studying for the CLAD and ran across that question. I had not used that before in programming and could not find a way to generate the same result to use the help functions in LabVIEW. Thank you!
