I have been trying to create a system using conveyor tracking and two conveyors but I keep getting the attached error message.

![](http://forums.robotstudio.com/webwiz/2839/ErrorSmall2.JPG)

I have followed the directions in the user manual. Import the geometry for the conveyor, create the conveyor mechanism with target points, save that mechanism as a library. Than, create a system using system builder and when prompted for the library file I point to the conveyor and get the attached error “THE SYSTEM COULD’NT BE CREATED!”.

Any help provided would be very much appreciated.

Thanks!

Hi,

Have you created Wobj frame while conveyor creation ?

Hi,  
Sorry, I have no suggestion, but I also want to ask:smile:  
Can an encoder interface (DSQC 377 A) track 2 different conveyor?  
If yes, is it need 2 encoder in 2 conveyors? I read in the manual, that an encoder interface only can support for an encoder.  
Here I attach the layout drawing. I need to track the objects in conveyor A, pick them and place them to the trays in conveyor B.  
can I track the conveyor A and B together in the same time?

Many thanks.

Best regards,  
Carmila

Maybe there is a problem with the system name, since it seems to be the same as the station name, try changing it to something different to see if that helps.

I got it working…for some reason, everytime I creating the system, it asked me for the conveyor library. This caused duplicate conveyors in the systems. If I created the system without the conveyors, it asked me for them and works fine.

Thanks!
