Hi, 

I'm Chiara, an engineer at NI, and I'll be trying to help you out with this.  I think what you probably want to look at using is a Shift Register on your loop around the vision assistant, to record the last y value.

Some further information on shift registers can be found here:

Please let me know if this helps.

Best wishes,

hey chiara, thanks for the help. 
so far i have a shift register, that has a 3 reading buffer on it so if the image goes missing it has 3 samples to re-find it before it zero's

Hi, 

Great, I'm glad that you found the information useful and best of luck for your continued programming in LabVIEW.
