Process Data

The allocation of process data and the channel status information of multistate
output-configured channels for local override are described in 'Process Data
Channel Mapping' for the corresponding TX-I/O module.

If [MOValue] is invalid – i.e., the value exceeds the permitted range for the
assigned number of outputs, then
 a quality error message (Reliability) is generated
[Quality = MULTISTATE_FAULT]
 a backup value becomes valid according to the value in [BackupMode].
If the TX-I/O BIM is in the status 'Masterdown', a backup value becomes valid
according to [BackupMode].
