I have a KR30-3 with a KRC4 8.3.17 which has recently started showing "Could not set IP address" error. I have looked at other threads and tried disconnecting and reconnecting the smartPAD but without any success. I have also disconnected and reconnected the ethernet cables in X65 and X66 and rebooted but no change.
The error started occurring when a USB stick was inserted into one of the two USB ports on the front of the KRC4 cabinet. These have always been a bit dodgy and temperamental and could sometimes caused an Ethercat error (KSS13021) to be caused if the USB stick was waggled around too much upon insertion, but that could usually be cleared with rebooting the system entirely.
This issue is worse now though because at least with previous errors I could use the interface on the smartPAD, but now this isn't possible and I'm stuck after booting. I have a feeling that maybe the dodgy USB ports have somehow knocked some other connection out?
A side issue is that I'm trying to open the cabinet to connect a monitor to the KPC and cannot seem to unlock the front door? Am I missing something obvious here? I'm not using the supplied key but have just turned it using a screwdriver is maybe the issue? But the whole locking system seems to come out and the front door doesn't budge either way.
It's very likely we need to get the cabinet serviced properly, but in the mean time, are there any fixes that could be recommended?
