KRC2 error on writing driver DN2DVR

    KRC2 error on writing driver DN2DVR happens when started up in morning. After power has been on for 1 hour it is OK after a restart. 24VDC PS in cabinet reads 24 right after cold start. Any thoughts on this?

    how to post correctly:

    1. be a good citizen and follow common sense. this includes no sharing or asking for copyrighted material. such posts will get you banned (because we don't want Kuka legal team stepping in and request ban on all manuals). an example of something that will get you in trouble is any material from Kuka College.

    1.5 make SURE to post in the right forum section (manuals in manuals section, IIWA and Sunrise topics in IIWA section). see attached example for IIWA... sigh.. :tired:

    panic mode

    You can restart/reconfigure the bus via configuration menu, that's much faster than rebooting.

    Did you try it after one minute?

    Describe the bus topology.

    Forgot to add this: Digital outputs do not work until this error goes away

    Of course not -- those outputs are linked to DeviceNet, so they won't work when the driver is not operating.


    The DND message should include details as to which device has stopped communicating. Have you checked that device?
