How to map Automatic External signals over Ethernet/IP

    Hi All,


    I've been reading through the SI manual but a few things are still not clear to me.

    I'm very familiar with FANUC but KUKA is new to me.

    I'm using an Omron PLC to talk to the KUKA. I have the connection mapped and that part is ok, the PLC and Robot are talking.

    However I can't figure out how to map Automatic External signals to Ethernet/IP bus. I thought there would be a template or some kind of standard to map all the listed Aut Ext. I/O but I can't seem to find any way to do it.

    I have mapped 60 bytes of Input and Output to exchange with the PLC. How do I map Controller Ready to Byte 0, Bit 0 for example? And do I have to do all of them 1 by 1 (Fault, Drives Ready, etc.) ?

    Thanks in advance to anyone who can clue me in and help me connect these dots

    Approved the thread.

    You can find someone doing the complete configuration over profinet in this video. Since you already have the communication setup, you can just follow the part where the I/O mapping is done. The default $IN[] and $OUT[] for the External interface are listed in the SI manual.
