Connecting robot with welder

    Hi guys


    I need to connect OTC(AX21 controller) robot with NACHI PROFIBUS(anybus) interface board with FRONIUS welder also with PROFIBUS(Beckhoof BK 3120 interface). I have the profibus cable and I have some FRONIUS manuals explaining IO mapping addresses but I am not sure about master slave configuration.


    Should robot be master? Where can I choose this? and what address to set? maybe 0?

    Fronius welder I guess is slave. Node address 11.


    Maybe someone has some manuals for OTC/NACHI profibus configuration?

    Any help would be great:smiling_face::smiling_face:


    Thanks

    Hi again from Croatia


    here is the update with videos.

    This robot was used in welding cell and connected as slave to SIEMENS master PLC. Also FRONIUS welder was connected to same network as slave.



    Now I want to set only robot and welder. Direct connection.

    But without luck.


    On robot side is d-sub(9pin) Profibus connector with termination ON

    On Fronius side is also d-sub connector (Beckhoof BK 3120 ) with external power connected.

    I'm also not sure if this ANYBUS module can be set as master... :thinking_face:


    Here are the pictures and videos.

    UPDATE:

    I managed to remove ANYBUS module and read out the catalogue number. It is AB4005-C(i).

    It is ANYBUS-s SLAVE PROFIBUS DP.


    So I think I can't set robot to be master and welder to be slave. I need this:

    Any other suggestions?


    Thank you all :smiling_face:

    And stay safe ..


    Best regards
