Which device creates/starts the connection and which one waits to be connected to?  
Which protocol are you using?  
What information does need to be exchanged?

The kawasaki robot esablishes the connection. the cognex is waiting to be connected to.  
i’m using TCP. And want to get some X and Y coordinates from the camera.

TCP Communication is a bit harder on the Kawasaki robots. A working example can be found here:

[TCP communication: Cognex - Kawasaki](https://docs.google.com/document/d/1mYxNv3kXzpR99YYoSEOvfvQXt-AhsPEtmq-VFOGHbGE/edit)

My suggestion would be to put the code in the [Kawasaki IDE](http://ftp.kawasakirobot.de/files/public/Software/KIDE/) so you can upload the code real easy.

Good luck!
