How to share DIO between two separate Fanuc Controllers?

    Good afternoon all,


    I have two R30iA controllers, and need to share the DIO between the two robots. So robot 2 can see all the i/o from robot 1 and vice versa. How can I accomplish this without having to physically use copper wire from robot 1 i/o card to robot 2's i/o card? Any sort of Ethernet options available?


    For example, if my machine sends cycle complete as input to Robot 1, I want Robot 2 to know also, without having to use an output from Robot 1 and a physical wire for only one input into Robot 2. Make sense?


    Thanks you.

    Ethernet I/P can do this easily. I've done it before when I needed to run a 4 robot cell, and the plc was not setup. One robot will have to have the scanner option installed thought to act as the master. Other robots only need the scanner option.

    Check out the Fanuc position converter I wrote here! Now open source!
