Restting A Feedback Node

[MCU]

Hello,

In the attached VI the counter is not resetting. I am trying to reset it on every cycle of the outer loop.

Is this what you are trying to do?  If not let us know.

Right click on the feed back node and select Move Initializer out one loop.  Right now it is set to Globally Initialize.

For your example, a wait statement of about 500 msec in the inner loop and an indicator on the wire makes it easier to see what is going on.

Hello,

@jmcbee: That was the idea thanks.

In a While loop, Ravens Fan solution also worked.

Hello,

In my application I have a counter subVI that works like the Case structure above. However, on every cycle of the outer loop, I require the feedback node to reset (so that the count is zero when the inner loop runs again).

How is this best done?

Thank you

Hi MCU, I'm not sure I understand the difference between this question and your last one.  Are you having trouble creating a subVI?

[RavensFan]

How is this different from your original question?

I already gave you an answer and you said that it worked.

From reply #3 "Right click on the feed back node and select Move Initializer out one loop.  Right now it is set to Globally Initialize."

Hello,

In the original question the feedback node was placed directly in the loop (as in the picture). To reset it on every outer cycle I could move the node initializer to the inner loops border.

Now I have put everything inside the inner loop into a subVI (including the feedback node), so I cannot place the node initialzer on the border of the inner loop (since the feedback loop is now in a subVI).

How do I reset the node from the outside?

Thanks

The inner loop should be in your subVI as well as what is inside of it.   Is the inner loop in the subVI you just created or is the subVI in the inner loop of the top level?

There is nothing wrong with using a feedback node like this, but I am curious why you chose it over using a shift register.  It seems to me that shift registers are more intuitive, but maybe that is because I never use the feedback node.
