Startup program ("other method") changed after power outage

  • For the second time the startup program in one of my robots somehow changed. I do not remember the specifics of the first time, but today it changed after a power outage.

    Now what I do not know is whether it was truly the power outage that somehow reset the variable entry, or if some maintenance guy changed it in an ill attempt for troubleshooting.


    Any ideas?

  • In such a case I would create an AoA backup and take a closer look into the logbook file which is part of the AoA backup. If somebody made a change you will definitely find some hints within the logbook.

  • Did it change to something else, or is it empty? If someone has UI17 PNS_STROBE mapped to a digital input, and toggles true, it will wipe clear your "$shell_wrk.$cust_name" and your robot will just sit there doing nothing after you send it a start signal.

    If it changed to something else, then I'd say someone is changing it.

    Good idea, ill try that, thanks!

    It was changed to something. A non-existing program btw. However, the name is similar to existing programs, just a different number suffix.

    Do you have a cold start autoexec program? It would be listed under SYSTEM > CONFIG

    No cold start autoexec program, I just checked.

  • Did you ever get this resolved? I'm running into this now. Sometimes, on power up, the robot changes the OTHER program from 'MAINLINE' to 'PNS001', which doesn't exist on this system.
