Hello

A month ago the safety configuration code is ’ DDDD DDDD '.

But now, the safety configuration code is ’ 5894 B181 '.

How can i get back the safety configuration as ’ DDDD DDDD '.

I set it up as similar as possible to a month ago, but the safety configuration code is not the same.

The robot is UR5e. Last Update is may, 2023.

Thank you

That checksum is generated every time the safety configuration is changed.  
The only way to get back to an old checksum would be a full image restore.

But a checksum of DDDD DDDD also sounds like it was just defaulted after installation and never configured in the first place.

Thank you for reply.

I solve this problem, and I find How make checksum as default.

that is create a new installation file.

And, DDDD DDDD is default that Robot Limits is Factory Presets:Least Restricted.
