Does rewriting the Safety of Safemove without applying any changes alter the checksum?

MelissaDM

As I understand it, the checksum is tied to the Safety module. If I rewrite the Safety controller without making any actual changes, does this still alter the checksum?

And if the answer is yes, then does restoring the backup revert the checksum to its original value?

Best regards.

I have heard from an ABB rep that the datetime when saving your safemove configuration is stored in the checksum. 

But if you download the same project without saving any changes the checksum should be the same AFAIK.

Thank you for your response. I actually analyzed both backups today—the original compared to the new backup where I rewrote the safety controller but kept the parameters unchanged (areas, signals, etc.). In doing so, I noticed that the checksum remained the same.
