Need Urgent help with PROFINET Siemens-FANUC communication

    • New

    Hello fellow programmers,

    I have a problem, basically im using an Siemens S1200 PLC and a FANUC CRX10ia robot with a R30iB mini plus controller.

    Im trying to establish a simple PROFINET connection between the two so that the robot acts as a slave to the signals sent by the PLC.

    The card in the robot controller has the code A17B-8102-0100 (through the document orderfil.dat from the AoA backup i have managed to find out its also refered to as: A05B-2600-S536 ! PROFINET FANUC board+), and i connected my PC to a switch and then connected the PLC and the PROFINET card to the switch.


    Problem is, 90% of the manuals i can find have menus which dont even exist on my TP (we have a tablet teach pendant), so they arent really of a lot of help).

    And im having a big big problem connecting to the robot, tried importing the GSD file into TiA and it throws the PLC into error and shows a lower level component error because the robot isnt found on the network (PLC is on IP 10.0.30.50, PC is on 10.0.30.30, and FANUC ethernet IP is set at 10.0.30.90) and the robot just doesnt show up in the accessible devices list.

    Also tried connecting the PROFINET card directly to my PC and pinging the ip but nothing happens, literally like the card doesnt exist. The link status LED is glowing orange which means connection is established? (according to the manual atleast), so i really have no clue what to do anymore... I thought about the fact that the "Ethernet IP" setting on the robot TP might be for the 2 ports that are located on the side of the controller (very much possible because when the PC is connected to one of those 2 ports, the ping works. But i see no option to change any other IP besides that one on the TP...


    I have been going at this for 2 straight weeks now with no real progress so im hoping somebody has some idea of whats going on..


    Pretty sure the problem is robot side since TiA does not even see it in online devices and im unable to ping it (when its connected from the PROFINET board).


    Also when switching the robot Device Mode to RUN it immediataely switches to stop and when confirming yes it says that its unable to reset.

    Some other (maybe) important details:

    Software versions, IDs:

    Software version: 9.40P/64

    Boot monitor: V9.40P/43

    Teach pendant: 7D0A/01P


    Controller FANUC R-30iB Mini plus

    Type: A05B-2696-B001


    If anybody has any idea of what to do, please help, im desperate for any working solution..

    Also if you require any other information or the AoA backup of the robot, just tell me i can send you anything needed.

    Thank you.

    Which .gsdml-file are you using?
    It should be: GSDML-V2.42-Fanuc-A05B2600S536V940X2P-20220518.xml

    Did you update your robot's software to the latest one available (and also updated the Tablet TP app)?

    The menus that are referred to in the manual (B-82864EN_10) should be available even in the Tablet TP app, if you go to the "Legacy" menus and not the CRX/Tablet TP UI.

    Also, the Ethernet ports (CD38A and CD38B) of the robot controller are not the ones that you will use for Profinet communication, so the IP address of the robot's Ethernet interface is irrelevant.

    If you have your Profinet card set to Dual Channel mode, then you need to use port 1 or 2 on the card (port 3 and 4 are for the I/O controller function). If you have it set to Single Channel mode, then you should be able to use either one of the 4 ports.

    From TIA Portal, you should be able to assign both Profinet name and IP address of the Profinet card, given that TIA Portal (your PC) and the PLC has an actual connection with the Profinet card.

    The IP address of the Profinet card can be viewed (and set) from the Profinet menu in the TP (Menu->Setup-Profinet, F3[Other]->Ethernet Address).

    Hi, and thanks for the quick response. To answer your questions:

    The only GSDML i managed to find on the FANUC website was:

    GSDML-V2.41-Fanuc-A05B2600S523V940X4P-20211018

    But through contacting FANUC support with my AoA backup they also sent me these two:

    GSDML-V2.41-Fanuc-A05B2600S523-20210531

    GSDML-V2.41-Fanuc-A05B2600S536V940P2P-20220518

    Could you prvide the means of getting the correct file if none of these 3 are correct?


    On the update question, me and my coworkers tried finding the way to update everything but as far as we managed to find out, the update files need to be aquired from directly contacting FANUC, or? If not, could you explain how and where would the updating be done automatically?


    And also for the Setup PROFINET menu, this is what we have there: (see attached image), and as far as we managed to find out we see no other relevant PROFINET menus besides this and I/O device setup.


    Really appreciate the response.

    Since your system has the software option for Dual Channel Profinet Fanuc Board (S536), you should use the one I mentioned. How to acquire the .gsdml-file other than either contacting FANUC or downloading it through a customer portal (there are different ones, depending on where in the world you reside) I don,t know.

    For updating the system software as well as the Tablet TP app, I would also refer you to the customer portal. At least in Europe there is an update package available (complete with instructions on how to do).

    The menu you showed is the correct one. By pressing F3 (OTHER) while in that menu, you can navigate to other Profinet-related menus. Might need to bring up the TP-keypad (the button in the bottom right corner of the Tablet TP App-screen).

    15 minutes ago we found the solution.

    Process was as follows (thanks to your idea gpunkt ) we updated the version from 9.40P/64 to 9.40P/73, then went on to do PNFBUPDT and after that everything was working flawlessly, we could finally put the card into RUN, looks like the profinet card didnt show up on the network because of mismatched firmware, FANUC also directly contacted us to send them our AoA backup (the old version) so they can find the bug in the firmware.


    Thanks for the help.
