I have the same problem, I have : 0x000c000f
I also get a KUET fault logged.
CaDI tells me that it could be a landing node faulty?
I have just swapped the top of car board and the slave COP board (LONCPI)
My lift has dual COP panels, the slave/ auxiliary panel.will sometimes have non responsive buttons
I have performed a node freeze many times
LONIC is not the issue here, LONCOP and LONCPI are in question.
0067 KUET is highly unlikely a LON related problem in your case. Check the magnetic switches KUET/KUET1 connections/distance to the magnets. Both KUETs have to switch at exactly the same time.
I guess EMC problems can be ruled out?
