Good morning Skyefire,
The KSS version is 5.2.15, it is a KRC2 KR60/3 robot.
No idea of that value ($PRO_I_O[]) but I'll check, in fact, there is some sort of problem in the backup operation, they can't perform the backup as a message like "the file can't be found" appears...
I'll get the status of the asked internal variable...
