Hi Guys,
Been years since I have done this stuff. I am struggling with the tracking/encoder and marrying the camera result data to the encoder count/ package location.
Here is the application.
Compactlogix 1769-L18ER-BB1B using 1734-vhsc counter module.
System has two cameras mounted on conveyor about 24" apart.
A single photo eye at entrance to zone starts the whole thing off.
I need to take the photo eye input and count X ticks before turning on camera 1.
The result from camera 1 (pass=1/fail=0) is then put into shift register...or should I use a fifo?
Then Y (24") ticks down the line turn on camera 2. Again pass-fail.
Then a reject device is z ticks(12") down the line needs to fire based on the pass fail of both cameras.
There will be multiple packages on the conveyor(6-10) at any time between entrance sensor and reject.
So I have a hacked up mess in the program and can't figure out the right way to do this. The 1734 counter module is a project in itself to me with all of the tags in it.
If anybody could provide some samples of both tracking the package pass/fail and firing the cameras based on encoder count and tracking the pass fail through the system I would greatly appreciate it!
Thanks
