I have altered the Profibus wiring recently, so yesterday I removed the modified cable and tried to reboot the cell, only one of the three robots came back up again
Speaking to Kuka they suggested this error code pointed towards the MFC2 card, though I can't see reference to the MFC2 card in the manuals I've got, there's reference to an MFC3 card, are they referring to the same thing? The MFC card would tie up with the altered Profibus wiring though..
