Function location

[Al92651]

I am looking at an application that is using a function that is a yellow square with a arrow going in a circle. I've looked through all of the palettes, but can't locate it can anyone help me out?

Doesn't ring a bell. Can you show us a picture of the VI icon?

What is the application you're looking at?

The VI could be from a NI toolkit, openG, third party driver, a private subVI, etc. etc.

Hi - do you have access to the VI itself, or just a sceenshot/printout?

If you can load the VI, enable the context help (Help->Show Context Help). Hover over the icon and a description/name should appear.

You can then search the function pallet.

Here is an image the yellow arrow is pointing at the icon with the arrow going in a loop.

Thanks

This is part of the while loop.

By default, the termination condition is set to "stop if true", showing a red octagon. RIght-click it and select "continue of true" and it will look like on your image. 🙂

Okay, worked great. However, the stop icon is still there along with the loop, and when I tried to connect the 'less than' symbol I get the 'x' error, 'this wire connects to more than one data source.' The stop icon, see attached, is not shown in the application I'm working through, see image in previous reply. But if I delete the Stop icon the connect is okay, is this a legal operation?

[altenbach]

Your wire has two sources (the output of the comparison and the stop control), which is of course not allowed. A wire can only have one data source.

You can wire the two souces to an boolean OR or AND (depending on what you want) and wire the result of the logical operation to the termination condition.

I would recommend to use "stop if true", especially since you use a stop button to keep it all more logical. You can invert the comparison to match.

BTW: your formula node could be replaced by a simple "multiply" from the numeric palette. 🙂
