  • KUKA Interface X12 with 16 I/O and Devicenet connection with PLC Siemens I/O

    Good evening,

    I'm working with a KRC2 KUKA that has to communicate with some devices by KUKA Interface X12 with 16 I/O connections and with Siemens PLC by DEVICENET,using ADFWeb converter.

    Interface X12 is working fine, I assume I can use both the communication togheter so I tried to start Devicenet but something is wrong and it doesn't work.

    I've checked some thread about cable connection and configuration file and everything looks correct according to examples and manuals:

    • Kuka is Master and I use a ADFWeb Devicenet Converter as a slave to connect Kuka with Siemens PLC in Profinet (checked MACID=5 in both side and 4 bytes inputs and 4 bytes outputs seems to be configured properly in Siemens and in Kuka).

      devnet.ini

      [krc]

      debug=1
      baudrate=500

      [1]
      macid=5

    • iosys.ini:

      [CONFIG]
      VERSION=2.00
      [DRIVERS]
      MFC=0,mfcEntry,mfcdrv.o
      DEVNET=2,dnInit,dndrv.o

      [MFC]
      INW0=0 ;$IN[1-16]
      OUTW0=0 ;$OUT[1-16]
      OUTW2=2 ;$OUT[17-32]
      [DEVNET]
      INW4=0 ;$IN[33-48]
      INW6=2 ;$IN[49-64]
      OUTW4=0 ;$OUT[33-48]
      OUTW6=2 ;$OUT[49-64]

    • Devicenet cable is done according standard (I've checked also some configuration sample ) but in Kuka's card even if pin 1 and 5 are powered with 24V external to Kuka, with proper resistor betweekn pin 2 and 4 , leds are not blinking, so I guess I just forgot something in cabling or there will be something I miss in configuration in Kuka.

    Can someone please provide me some examples of devicenet cabling/configuration...and if possible to suggest some method to understand if X801 is working ? (I've checked Rj45 on the right side of the same card and with ethernet connected leds were blinking but I don't know if it means something).

    Thank you with advance.

  • KUKA Interface X12 with 16 I/O connection with PLC Siemens I/O

    Good evening, I'm programming a Kuka Robot of 2003 with KRC2 and I need to connect it, through KUKA Interface X12 with 16 I/O card, to digital I/O of a Siemens 1200. From KUKA Interface X12 manual, I understand that each Output group has is own GND and Power supply and each Input has its 0 Potential.

    How is the best way to make this connection? With other devices that needs reference and power supply in the system I'm using the same 0V and 24V of PLC, may I use the same for those Robot's I/O?

    Thank you for suggestions
