    Hi everyone.

    I have an issue with a robot fanuc, controller R30ib

    Actually the robot is working well with 7 PNS programs, i understand that we can use 8 PNS bits in a linear combination to call programs from an external device (UI[9....16]) in this case is an Allen Bradley PLC.

    The plc makes a comparation between what it receives from the robot and what he send.

    The problem cames when we try to add more PNS, for example PNS008. The next bit necessary for the linear combitation is the ACK4, when the plc makes the comparation above discribed, the UO[14] [ACK4/SN04] start to toggle on/off and this makes the routine in the plc get lost.

    Any idea of what i'm making wrong or what are i missing?

    :frowning_face:

    How is your PLC and robot communicating? Hardwire, EthernetIP?

    I would verify the input and output mapping of your UOPs, and verify that nothing is double writing to the UOs.

    I had a cell do this in the past, and it turned out someone had double mapped some of the UOs.

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

    Check out my example Fanuc Ethernet/IP Explicit Messaging program here!
