How can I reinitialize a feedback node in a SubVI and in a timed loop

[ehsan11]

Hi everyone

I have a SubVI counter in a timed loop (LabVIEW FPGA ) , in this SubVI I have a feedback node with some initial value , but when it is called multiple times , I noticed it take the last value in previous execution and not the initial value .

How can I resolve this issue ? the outer timed loop runs infinitely

Right-click on the feedback node and select "Move Initializer One Loop Out".  Wire an initial value to the initializer terminal.

Or just wire the initialiser terminal at the bottom of the Shift Register, same effect.

I tried this , but still it doesn't work and maybe because it is an infinite loop and from host the initial value get called only once . 

Still after first call , in the next calls the initial value is previous executed value 

Is there a way to solve this issue without shift register or move init out of loop?

Hi ehsan11,

By definition, a feedback node gives the value from the previous call.

You can add a mechanism to reset your counter under some condition by doing this:

Or similarly:
