Communication between two robots

Hi community, I’m currently desingning a workcell with two robots. I need to do a very simple bool signals exchange between the two robots, I’ve read about GP I/O’s but i can’t get enough documentation and explanations.

Is there a way to exchange those signals between my two robots?

Thanks in advance.


UR is Modbus/Tcp server natively. A lot of data are available see : https://www.universal-robots.com/articles/ur-articles/modbus-server/

And it’s also easy to add clients channels : https://www.universal-robots.com/articles/ur-articles/using-the-modbus-tcpip-client-interface-of-the-ur-robot/

By this way data can be echanged automatically without one line of code.


I’ll give it a try today. I’ve got confused with the General Purposes I/O’s and fieldbus.

Thanks again Frederic.
