Help! KRC4 Unhandled Error

What Kss version are you using?

What was the robot doing when the error appeared?

Have there been any changes made to the system in the last few days? or perhaps software updates?

After reboot does the error come back and if so when during boot does it appear?

Have you tried disconnecting the SmartPad and connecting a DVI monitor directly instead?

Do you have a backup with a working version of the project?

What is confusing about the error? Did you read it and try to understand what it tells?

How much clearer it could be?

It very clearly states why KSS does not want to load:

1. It names troubled file

2. It says what line in file it has problem with

3. It says why it has problem with it - duplicate entry

So just restore problem file with one from the backup you collected before making changes.

Or read the file and correct it by hand if you understand xml.

Otherwise simply restore working image that was collected just before changes were made.

Either way, resolving this will rely on how prepared you were before making modifications.

Btw problem is not the smartPad, it is the content of the hard drive that is no longer ok. You may reboot as many times as you like but same content will be read every time and result will be the same until problem file is fixed

Quote from Yuhang Guan

The KRC4 version is 8.3.35.

When this error appeared, robot was doing nothing, just stop there.

Before this error appeared, I just depolyed an WorkVisual project to the robot via KLI, about I/O mapping between KRC4 and Beckhoff product. There is no system software updates for several months.

Yes, I have already rebooted dozens of times, but no help.

Here is a clue:

when I connect my smartpad with other KUKA robot, it works fine;

when I connect other KUKA‘s smartpad with my robot, there is still this error.

So I think the problem is KRC4, but I don't know how to fix it.

Problem is with Your SmartHMI.user.config file.

It probably gone corrupt after last WoV project deploying.
