I think I managed to change the wrong IP configuration field in the RSI Network tool on the KRC4 and ended up modifying the Virtual IP. I get the same symptoms as described in this thread: https://www.robot-forum.com/robotforum/kuk…r-cannot-start/ except it's on an KRC4 and not a simulated environment. The same error dialog is shown on the Smart HMI.
Is the only way to fix this by obtaining a Kuka USB recovery stick?
It's not possible to somehow minimize the Smart HMI or don't start it upon boot, and then go back to the RSI Network tool?
Why is modifying this even possible if it only breaks communication?
