The allocation of process data of binary output-configured channels is described in
'Process Data Channel Mapping' for the corresponding TX-I/O module.
If the TX-I/O BIM is in the status 'Masterdown', a backup value becomes valid
according to [BackupMode] after the [BOBackupDelay] delay.
If the device detects a [PowerDown], a backup value becomes valid according to
[PowerDownModeAC24].
