IMAQ edge tool 2 "First + last edge" - returns position only of the first edge

[xombox@seznam.cz]

I`m using "IMAQ edge tool 2.vi" with  Process set to detect "First and last edge. It`s obvious from Edge infromation indicator that it returns only one point coordinates. Where are the coordinates of the last edge detection?

Note: it detects edges along the long green  horizontal line, so there are definitevely at least 2 edges.

Thanks for advice.

Hey Martin,

This may sound silly, but what happens if you scroll to the next entry in your cluster? Right now you are displaying the information for your '0' edge on the front panel. What happens if you index to the '1' edge in your cluster and hence look at the information on the second edge. Is the cluster blank when looking at the 'zero' edge? If it is, perhaps the settings on your find edge step are too strict and the step doesn't pick up on a second edge.

If the problem persists, perhaps posting your sample vi and a sample picture will help clear things up.

Hope this helps!
