Kss00404 safety stop error

    what is your safety interface?

    how did this start? what change was done to get here?

    what is the controller type and what is the KSS version?

    the only thing that can do this is if someone modified WoV project or modified hardware connections.

    did you try reverting changes?

    also please check message logs. message KSS00404 is NEVER alone. the fact that on your system it is the only message shown suggests that original message is either suppressed or it intermittent (short lived). this means you really need to check the logs, not just live message display.

    so try menu > Diagnosis > Logbook

    1) read pinned topic: READ FIRST...

    2) if you have an issue with robot, post question in the correct forum section... do NOT contact me directly

    3) read 1 and 2

    I have attempted numerous solutions to address this issue. All safety aspects have been thoroughly checked and confirmed to be functioning properly. I replaced the safety board with another controller, yet the problem persists. I also switched X11 socket from another controller, and despite this change, the fault remains. I jamber on X11, but the issue persists.

    I factory-reset the controller and rectified all visible faults, leaving only this KSS00404 error. It appears in manual mode, but when I switch to START UP MODE, it doesn't show up. It only surfaces in T1 and T2 states. I also replaced the SMART_PAD with one from another robot, but the problem persists.
