Feedback Node

[ThePotatoMan]

Hello,

I've a question regarding the Feedback Node.

Currently, we are connecting cluster to an unbundle. However, when we connect it, a Feedback Node will appear.

As we're doing data logging, this feedback node will save our previous value and use it in the next loop.

But we do NOT want this to happen.

Is there any way to take this waay ? Because the feedback node will be automatically connected to it.

Please assist.

Thanks.

Hi Potato,

remove the (default) checkmark in the options dialog -> "block diagram" before "automatically insert feedback nodes"...

Erm, this is what I get after removing the feedback node and connecting it.

Why is this happening ?

Thank you for your assitance.

Hi Potato,

the feedback node is needed because of the loop: the output of first VI is input of 2nd VI, whose output is used as input for 1st VI... Such loops require a feedback node (or shift register)!

When you open the error dialog (Ctrl-L) it will tell you the same thing...
