In the "Report system errors" dialog, "Diagnostics support" tab, "Status enabled/disabled" area,
the check mark must be set in the "Query device status enabled/disabled" check box after CPU
startup and optionally in the "Output message at status change" check box.
For example, "Status cannot be determined" is always displayed while the CPU is in STOP
mode, or during startup evaluation of "Report system error" for all the configured I/O modules
and I/O systems after a CPU restart.
However, this status can also be displayed temporarily during operation if a diagnostic interrupt
burst occurs at all modules.
It is not possible to determine the status of modules on a subsystem that is connected to a CP.
