Can you point me in the right direction for combining multiple signatures into a vision sensor "code"? How does that work? How do you add it to a program?
The first step is to define some signatures ("Objects" tab). Once you've done that, you should be able to type a comma-separated list of signature numbers in the boxes on the "Codes" screen.
For example, say you've defined SIG_1 as detecting red objects, and SIG_2 as detecting green ones. You can now define a code that detects when you have the color red next to the color green by typing 1,2 in one of the code boxes.
As for how to use them in a program: that depends on what environment you're using (RMS, VCS, PROS, etc).
I hope that helps
