Logover user automatically logout after X minutes (independent of his activity)
There are no hidden features in the advanced user handling.
If you enable logover and also enable an inactivity limit + user any idle workplace will return to the idle user.
I believe this was developed to fit some pharma requirements. Any inactive workplace should "logout" itself to prevent unauthorized process manipulation, but still be running and show a process display with live values. A "screensaver" that blanks out access, not screens.
If you need other functions, eg a "grim reaper" cutting access after a preset delay you must speak with your regional ABB sales representative and ask him/her to forward an enhancement request.
