Result case 2: does not return to the effective range on time
The "Effective range exited without logoff" dialog box opens.
The HMI device triggers a local rampdown and log off from the effective range.
As long as the operator does not confirm log off from the effective range, the dialog box is displayed
on the HMI device. The operator is not able to interact with the machine. The effective range remains
in use.
When the operator has confirmed logoff from the effective range, the HMI device is logged off from
the effective range and the effective range is then released for logon for other HMI devices.
