• The flash memory for protocol data is
faulty.
• The Protocol Data File (BACKUP

restore operation failed when restoring pro-
tocol data from the CPU Unit’s Memory
Card to the Serial Communications Unit.
• Transfer the protocol data to the Unit.
If the problem persists after correct
protocol data is transferred, replace
the Unit.
• Write (backup) the protocol data from
the Unit to the Memory Card again
and then execute the restore opera-
